- 摘要：It was at the beginning of this century that the assessing of China's Pe-troleum resource was initiated from the view point of geological science.Through exploration practise of more than 80 years,the understanding,evaluation and prediction of China's petroleum resource have experienced a long process,i.e.from geological inference to geological analogue,from qualitative to quantitativeevaluation.This historical process may be generally divided into four stages:1.The stage of geological inference started from the beginning of this cen-tury and ended in late 40's.In order to probe into the potential of China'spetroleum resource,a lot of bassically route survey had been carried out by afew pioneer geologists.After that,they foresightedly concluded that there areprospects of petroleum in China,and that petroleum can surely be generatedfrom continental deposites as it is in marine sediments.2.The stage of large scale petroleum prospecting and exploration were car-ried out mainly in Meso-Cenozoic continental basins and resulted in the dis-covery of the famous Karamay and Daqing giant oilfields.This important dis-covery enables our government anouncing stately to the world that the days ofdepending upon the import-oil had gone forever,and enables the policymakerto decide stratigically that China's petroleum industry should be undoutedly based on the crude oil and natural gas,industry of man-made oil would beexisted continuously only in a complementary scale.3.The stage of nationwide qualitative assessment from 60's to mid 70's.petroleum prospecting and exploration work had been taken place in every im-portant inland sedimental basins,and research tasks have been deepened eitherin petroleum geology or in geophysical and geochemical survey.Whereasexplorations of our leading geologists with the utilization of their own cre-atire theories,such as tectonic-controlled petroleum distribution,polycyclepetroleum generation and accumulation,oil origin and distribution regularities of oil and gas fields in terrestrial deposites,etc.all came to an end that China's petroleum resource is very plentiful,say,100 billion tons or more as itwas preliminaily estimated.4.Quantitative assessment stage from the year of 1978 to early 80's.The formation and distribution regularities of fault-block oilfields,subtle pools,paleoburied-hill oilfields,thrust-screened oilfields and the like are more tho-roughly sumarized,new concepts and methods are introduced from abroad.As a result,it is evaluated that the crude oil resource of China is about 60-66 billion tons and gas 20-25 trillion m3.The second round of large-scale petroleum prospecting and exploration having been carried throughout the country and its frutful initial achiements obtained in East China Sea,South China Sea,and Tarim Basin have proved that a brilliant perspective of petroleum industry in China is unfolded before our eyes.575|495|0更新时间：2023-05-30

- 摘要：C1-C7 light hydrocarbon of 150 canned cutting samples collected from a test well are analysed with capillary GC so as to study the regularity how light hydrocarbon composition varies with buried depth.Light hydrocarbon is mainly methane when rocks yielding it are buriedless than 2,650m;the ratio of(C2-C4)/(C1-C4)increases rapidly from less than 30% to 60% when buried depth is about 2,650m;but C4-C7 turn to bethe primary components when buried more than 3,650m.It is obvious that with the increase of buried depth,the content of N-alkana and cycloalkane increases gradully while the iso-alkane decreases.Within the depth of 3,750m,cyclohexane/cyclopentane ratio increases with the increase of the depth,suggesting that cyclohexane is more stable than cy-clopentane in thermo dynamics.But the ratio shows obviously a decrease tendency with the increase of depth,when it is buried bellow 3,750m,this ap-pears to be related to the preferential aromatization of cyclohexane.In accordance with the mass-producing of wet gas,the methyl cyclopentane/cyclopentane and methylcyclohexane/cyclohexane ratios get the maximum values,similar variation is also observed in the dimethyl cyclopentane/cyclo-pentane ratio.The ratio of 1,1-dimethylcyclopentane to isomers of dimethylcyclopentaneis usually less than 0.1 and changes slowly when the buried depth is shal-lower,but increases rapidly to more than 0.3-0.4 when buried greater than 3,300m.It is believed that differential evolution and maturation are probably thegeneral characters in the evolution process of organic matter,and various ra-tio of light hydrocarbons mentioned above may be considered as indices ofmaturity.502|657|0更新时间：2023-05-30
- 摘要：In accordance with the recent results of several seismic sections accross Takli-makan Desert in length and breadth made jointly by Sino-American geophysicis-ts,the tectonic evolution and division of Tarim Basin have been studied andpresented here.It is considered that three stages in the basin's evolution process may be divided,i.e.,the formation of geosyncline and platform basement during Archaeozoic;the formation of sedimental blanket of platform during Sinian-Paleozoic and the formation of a continental sedimentary basin of Meso-Cenozoic.Among them,the last stage can be further subdivided intoTriassic-Jurassic faulted basin substage,the Cretaceous-Eogene faulted depression substage,the Neogene depression substage and the Quaternary depauperization substage.Thus the basin is recognized to be a superposed complex hydrocarbon-bearing basin with polycycles.According to its structural features,the basin can be divided into eleventectonic units of second-order,i.e.Central uplift,Tabei uplift,Baicheng depres-sion,North depression,Southwest depression and Southeast depression,and Qiemo-Ruoqiang,Kuruktag,Keping,Teklic and Altun faulted uplifts.Source rocksfrom Paleozoic to Tertiary system are well developd in this basin.Among thesetectonic units,Tabei uplift is the best in hydrocarbon potential,followed suc-cessively by Southwest depression,Baicheng depression,North depression,Central uplift and Southeast depression.Taking other hydrocarbon-bearing basinsinto account,Tarim is the fouth largest one in China.684|511|0更新时间：2023-05-30
- 摘要：A view of dual and triple pore-medium of pore-group is proposed in this paper.According to macroscopic observation and data analysis of capillary pressure test in core samples,it has been proved that a few non-fractured pore-networks coexist with each other in the conglomerate reservoir of the Lower Wuerhe Formation,the 8th district of Karamay oilfield.In well testing,the re-servoir of this kind shows the feature of dual or triple pore-medium curves.In order to feature precisely the property of such reservoir with multiplesets of pore-network,a new conception of pore-group is termed by the au-thors,thus the geometric property of pores is closely connected with its geo-logical origin.What's more,this new conception reveals profoundly the natureof seepage flow in the reservoirs—the basic framework of seepage flow in reser-voir is formed by the combination and interaction of pore-groups.518|663|0更新时间：2023-05-30

- 摘要：The natural gas of Wenliu gas pool in Dongpu depression,Henan Provin-ce,is considered to be originated from coal series of Permo-Carboniferous.The reservoir rocks are Lower Tertiary sediments.Methane contents of the gas is 95.12%,the ratio of C2-4 alkane to C1-4 alkane is 3.84%,condensate is22.98g/m3.The average value of Ar40/Ar38 is 1,231,much greater than thatof oil field gas in the same system of this same depression(441 for the oil-field gas)whereas δ13C-average value of methane is -28.16‰,which is 12.86‰ higher than that of the above mentioned oilfield gas,δD value is -182‰,Hg is 5.11×104ng/m3.δ13C-value of the accompanying condensate is -24.5‰,while paraffin in-dex is 8.09,heptane value 41.76%,benzene 11.04%,methylbenzene 5.94% and its peak carbon mumber is C11 or C13,Pr/Ph is 0.77.638|801|0更新时间：2023-05-30
- 摘要：A major intracontinental Mesozoic continental basin in Huabei plate was developed when the Yangzi plate obducted towards Huabei plate.The collision has caused the lithosphere of the former to be depressed and forced the isostatic compensation surface to low down,thus leading to its further development.The compressional stress was exercised on and controlled by both the Tethys and Pacific plates.The eastern margin of this basin had gradually migrated westward under the influence imposed through activities of the Pacific plate.In the Later Trias-sic,this basin involved an extensive area west of Tanlu fracture zone;in the Jurassic,its eastern margin migrated to the west of the Taihang Mountains;whereas in Early Cretaceous,the basin was confined only in Ordos region.Meanwhile,coarse wastes of great thickness were accumulated along the northand south parts of Helan Mountains.The Alxa deltaic massif,being compressed both by northward pushing of the Tethys plate and the southward advancing of the Augaris,produces an eastward component force,and,with the lapse of time,results in a eastern migrating fore-deep type depression along the eastern margin of the massif.Because of the continuous activities of the Tethys and Pacific plates,the Earlier Cretaceous basin continued to remain in the Ordosregion,and has brought about its original configuration ever since.Thus the influence of the tectonic activities can be seen clearly from the regular anti-clock wise migration of the depocentres during the Later Triassic,Jurassic and Earlier Cretaceous.667|852|0更新时间：2023-05-30
- 摘要：Thermal evolution of Fushun and Maoming oil shales is studied by Fischer Assay and Rock-Eval,and aromaticities of pyrolysis products are measured by nuclear magnetic resonance and fixed carbon ratio.In respect to the behavior of aromatic carbon and aliphatic carbon during thermal evolution,the authors found that the aromatic carbon pyrolysis residue remains unchanged,and the carbon contained in oil and gas are primarily originated from aliphatic car-bon.Thus an evolution model of organic carbon fractions of kerogen is sug-gested.In consideration of the mass balance of aromatic carbon and aliphatic carbon during evolution,an equation relating oil and gas yield P,to the orga-nic carbon content Corg and the“quality parameter”of organic carbon Kc isderived as follows:P=1.2 CorgKcWhere Kc is equal to(fai/fao)-1,fai and fao are the aromaticities of samples after and before the evolution respectively.The calculated values are checked by Rock-Eval experimental results,the average error is less than 10%.683|625|0更新时间：2023-05-30

- 摘要：The Upper Triassic reservoirs in Sichuan Basin are composed of sandstones.The porosity and permeability of them are very poor,i.e.2-10%(averaging 6.8%)<1md,pore-throat radius is less than 1μm.The voids,observed in rock slice,casting slice and SEM,are mainly secondary solution pores and the intercrys-tal pores of authigenic clays.The development of these secondary pores are related to the diagenesis which is controlled by the component,fabric and sedimentary environment of the sandstones.With poor compressive resistance,strong mechanical compaction,the lithic sadstone and graywacke are considered to be sediments of alluvial fan.The porosity here is less than 2%.Littoral quartzose sandstone is cemented by silica with well-developed quartzovergrowth.The secondary porosity is not developed so well for lack of solu-ble minerals,and the average porosity is only 2%.The original intergranular pores of the feldspathic and lithic quartz osesandstones are vanished owing to mechanical compaction,secondary changes of debris and the infilling of authigenic clay mineral during diagenesis,but the in-tercrystal pores of authigenic illite and kaolinite,and dissolution pores in the feldspars and calcites are well developed.These pores become the main reservoir pore spaces of the sandstones in the Xujiahe Formation.Being deposited as deltaic or fluvial sediments of meandering stream,the porosity and permeability of these sandstones are rather low.539|875|0更新时间：2023-05-30

- 摘要：1.It is proved that the Miocene Series is featured with stable heavy minerals,and the Pliocene with unstable minerals.Common augite bed appeared in the middle of Pliocene is the counterpart croped out on the earth's surface,i.e.augite sandstones,and constitutes a key bed.2.The unconformity between the Xiyu Formation conglomerate and the under-lying Artux Formation are found very often at the margin of the basin,but itchanges gradually into conformity inside the basin.Large amounts of pyro-clasts are discovered in the gravels of the Xiyu Formation,whereas in the Ar-tux Formation,pyroclasts are very few.Common augite bed found above theuncomformity interface in Taiss section proves that this key bed is located at the basal of the Xiyu Formation.The gravels under the key bed of augite sand-stones in Pusa section are composed mainly of sedimentary and metamorphicrocks,but pyroclasts increases greatly above the key bed,showing that the boundary between the Xiyu Formation and the Artux Formation should be lo-cated properly under the key bed in successive sections.The same result is obtainedwhen seismic reflective waves are used to trace the boundary.Abundant ostracod and charophyte fossils—generally Candoniella-Cypridopsis-Cyclocyprisfossil assemblage—are collected above the key bed both on ground and in boreholes.In correlation with regional strata,it is appropriate to consider the XiyuFormation to be in Middle to Late Pliocene.3.In wells,the basal of the Pliocene Artux Formation site in 4,800-5,400m deep in Guman structure,4,500m in Yengisar structure and 1,600-1,800m in Kokyar anticline.It is obvious that there are very thick sediments of the Xiyu Formation in Guman and Yengisar structures,that is why the Miocene Serieshad not been drilled in well Guman-2 though this well had drilled in 7,002m.4.The oil reservoir of Kokyar anticline sites generally below 3,000-4,000min depth.It is coarse grained,rich in argillaceous gravels and stable heavy minerals,Corresponding with that of Karato anticline in the west of Kashi City,it should be considered as the lower part of the Pakabrak Formation.Oil shows have been found in well Qibei-1,So it is believed to be an important target reservoir of the Tertiary System in this region.526|493|0更新时间：2023-05-30

- 摘要：Hetian fault belt is one of the major fault belts along the southwest margin of Tarim Basin extending more than 300km and dipping south with dip angles of 20-60?.It cuts through the Upper Proterozoic to Pliocene strata and lay consealed under the Pliocene.It was initialed in Early Permian and has undergone several stages of evolution.High-dipping anticlines such as Piaman,Duwa,Sangzhu,Yuliqun and Pusalocate on the upthrown wall of this faul belt,whereas low dipping anticlinesas Keliyang and Kokyar on its downthrown side.Among them,the long-axial Keliyang anticline,screened by the north walls of Sangzhu and Yuliqun antic-linal structures,contains the favourable Middle Jurassic source rock and thepossible Eogene source rock.It is obvious that when the source material is matured in Late Miocene,the fault belt could be a fine passage for hydrocarbon migration,while synchronous Keliyang anticline provides a favourable space for hydrocarbon accumulation during Late Miocene-Pliocene.In accordance with the fact that secondary oil and gas pools are discover-ed in Miocene Series of Kokyar structure,and oil shows corp out on the north walls of Sangzhu and Yuliqun structures,the author points out that Keliyang subtle structure could be inferred to have good petroleum potential.598|518|0更新时间：2023-05-30
- 摘要：Manite depression is one of the largest depressions in Eren Basin.It covers an area of more than 10,000km2,trending NE.It is a Meso-Cenozoic depression developed on a folded and metamorphic Paleozoic basement,and under wenta long process of tensive faulting-block faulting-subsidence-degeneration.Sedimentary formation is mainly composed of Jurassic-Cretaceous rocks with athickness of over 6,000m.The varied sedimentary facies,controlled by the majoractive fault at the margin of the basin,includes diluvial deposites,alluvial fan,fluvial sand,valley flat and lacustrine sediments.The facies zone change intensively and the thickness of each is unstable.But along the fault in the center of the depression,some synchronous depressions developed there.These depressions keep their own inherent properties,distribute in series with thicker sourcerocks and abundant organic matters,favourable for hydrocarbon generation.Inside the depression,there are two petroleum generation segs with one upliftin between,i.e.Aershan fault belt which possesses good reservoir and caprocks and different types of traps.In the early stage of exploration,commercialoil and gas flows were obtained from five traps of the fault belt.It is thus proved to be the best hydrocarbon enrichment zone of Manite depression.670|463|0更新时间：2023-05-30
- 摘要：The east-west trending overthrust belt along the southern margin of Jiuxi Basin,Gansu Province,extends 100km long and 10km wide.This belt is composed of the fault on the south margin of the basin and the one on the north side of Laojunmiao anticline.These listric faults dip to south,and their dip angles are usually ranging 20-60?.Anticlines such as Shiyougou,Laojun-miao,Yaerxia,and Qingcaowan are all on the upthrown wall of the fault on the north side of Laojunmiao anticline belt.It has been proved that commer-cial oil flows have been discovered in the above mentioned first three anticlines.The trap type of these anticlines are considered to be nappe-related drag folds and intermediat fault blocks.Qingxi depression on the north side of the over-thrust belt is the largest depression in oil generation within Jiuxi Basin.InUpper Jurassic-Lower Cretaceous,there are favourable source rocks.It is pre-dicted that new subtle oil pools could be discovered on the downthrown wallof the overthrust.592|461|0更新时间：2023-05-30
