- 摘要：The Late Triassic Xujiahe Group in West Sichuan Basin consists of two kinds of ab-solutely different depressed sediments.The lower basin is the depression of continental margin while the upper basin is fore deep depression resulted by intensive orogenic move-ment.The important tectonic movement leading to the above mentioned transform inquality now have been proved and is named Anxian orogenic movement(Anxian Move-ment for short),which corresponds to the second episode of the Indo-China movement—Pre-Rhaetic orogenic episode.The 4th and 5th members of the Xujiahe Group are absencein the Longmen Mountains and its foreland area,and the Jurassic Systen overlapped onunconformity,thus leading to the misunderstanding for the movement time,that is,themovement was considered to occur in between the end of the Triassic and the fore of Jurassic for a long time.The Anxian movement is not a locally geological phenomena,buta signficant geological event of Chinese Plate colliding with exotic plate.The foreland of the Longmen Mountains is the front edge of intensive zone of the orogenic movement,and the boundary between back-arc overthrust and regressive arc basin that is the boundary between active and stable belts.This movement plays an important role in hydrocarbon dis-tribution to the west part of Sichuan Basin as well as the whole region.关键词：四川盆地;须家河群;安县运动;印支运动;龙门山704|447|0更新时间：2023-05-30
- 摘要：Cambrian carbonate gravity flows in Guizhou and Hunan are various in kind.Debris flow calcirudite is the main redeposited carbonate developed on the south and north slope of the Yangtze carbonate platform.Pulsation,undulation and flow-trasformation are very common in its flow process.According to the distribution range,horizon variation andcyclic property of the calcirudite,the south margin of the Yangtze carbonate platform generally progradated southeastward from the Cambrian to Early Ordovician,and the Yangtze landmass had reached the evolution stage of matured passive continental margin.关键词：碳酸盐重力流;碎屑流;寒武纪;黔东湘西627|564|0更新时间：2023-05-30
- 摘要：Experiments described in this paper show that carbon isotope composition of gaseous hydrocarbon from artificial maturation is similar to those from natural maturation.The same as that of natural gas,carbon isotope composition of pyrolyzed hydrocarbon can be used to indicate the type and maturity of organic matter in source rocks.Based on the re-sults of the experiments of thermal simulation of 8 source rock samples,the relationship between the yield of gaseous hydrocarbon,their carbon isotopic composition and the type,the maturity of organic matter in source rock is established,and then δ13C-value of both the pyrolyzed gaseous hydrocarbon in source rock and natural gas samples are used to study the natural gas and source rocks in Tarim and South Songliao Basins respectively.关键词：天然气;热解;模拟;碳同位素;气源对比619|349|0更新时间：2023-05-30

- 摘要：The Western Pacific oil-bearing belt where source rocks and reservoir rocks are do-minated by lacustrine deposits extends longitudinally across the whole globe.The forma-tion of the belt is related to the subduction and collision between the oceanic plate and the continent plate,the disintegration of the ancient continent,the influence of the ancient Pa-cific Ocean(and the Indian Ocean in the southern hemisphere) on the paleoclimate of thesedimentary basins and the promotion of high geothermal value for the formation of hy-drocarbon.The lakes located in the north and the south of the belt are older (mostlyformed in the Mesozoic) than those in the central part (mostly formed in the Cenozoic),and are older in the west than in the east.Lacustrine facies have changed into marine fa-cies from west to east.The evolutionary history of the lake basins consists of three stages:faulted-subsidence stage,faulted-depressive stage and depressed subsidence stage.The ini-tial phase was dominated by filled-deposition,evaporation associated with source beds.Inthe middle phase,very thick source bed,sandstones and conglomerates derived from riverdelta,diluvial and turbidite phases as well as lacustrine carbonate were formed.The latephase was characterized by extensive and very thick sandstones and conglomerates which were deposited in fluvial environment.The duration scale and feature of each stage is alldifferent in distinct types of the basins.The Western Pacific oil-bearing belt mostly com-prises five types of hydrocarbon bearing basins which can be divided generally into threesubbelts.The first is non-marine subbelt(including near-inland depression basin,near-ocean depression basin and near-ocean faulted-subsidence basin),where both source bedsand reservoir beds (except for basement rock reservoirs) are lacustrine deposits.Big-andmedium-sized oil and gas pools are mostly bed rock pools,anticline (including drape-anticline)pools,plus small amount of faulted block pools,stratigraphic pools and lithologicpools.The second is transitional facies subbelt (including the faulted subsidence and de-pression composite basins on active and passive continent margin).This subbelt is charac-terized by the source beds of lacustrine facies which were formed in the early stage ofbasin evolution,and the reservoir beds of marine facies which were formed in the latestage.The big-and medium-sized oil and gas pools are composed of anticline (includingdrape-anticline) pools,reef pools and stratigraphic pools.The third is the Western Pacificisland arc subbelt basically consisting of marine deposits.The oil and gas pools in eachsubbelt are distributed around the hydrocarbon generation depressions.关键词：西太平洋;湖相沉积;油气聚集带;盆地类型;板块构造571|373|0更新时间：2023-05-30

- 摘要：The origin of gaseous hydrocarbon is discussed on the basis of geochemical featuresof natural gas in Sanshui Basin,Guangdong Province.The Cretaceous-Eogene Systems inthe basin have a thickness greater than 7600m.The Buxin Formation(E1-2b)contains morethan 500m thick source rocks in which kerogen is mainly types Ⅱ and Ⅲ.Vitrinite reflec-tivity(Ro)is between 1.2% and 1.9%.Eleven samples of natural gas have been analyzedfor gas components and isotopic composition of carbon and hydrogen.The results showthat geochemical characteristics of ignitable gases are:1.hydrocarbon-rich natural gascontains N2,He,CO2,but not H2s;2.the value of dry-wet indices (C1/ (C2+C3))has the range of 2.1-196 which can be easily separated into two groups:>18 and <8;3. iC4/nC4 ratios Change between 0.42 and 0.87;4.the value of δ13C1 and δ13C2(PDB) ranges from -61‰ to -44‰ and -33‰ to -30‰ respectively;5.δDC1 value(SMOW) has the range of -237‰ to -174‰ which reflects the genetic process ofmethane and salinity of sedimentary water.Dry gas found in the highest part of structureis distributed in the area in which oil field water is of NaHCO3 type with a lower intensityof mineralization (25-50 g/l).The carbon and hydrogen isotope composition(δ13C=-60‰ and δD=-236‰--174‰) of methane in dry gas are identical with those of bio-genetical methan.Wet gas (C1/ (C2+C3)<8)in company with crude oil is rich in13C(δ13C1=-48‰--44‰,δ13C2=-33‰--30‰).The difference between δ13C2 and δ13C1changes from 14.7‰ to 15.2‰.The isotopic compositions of wet gas conform tothose of oil-type gas from Zhongyuan and Sichuan Oilfields.Wet gas is found in the areathat has Na2SO4 type of oilfield water with a higher intensity of mineralization (50—100g/1).All of the geochemical evidences confirm that dry gas in Sanshui Basin is generatedby microbe altering organic matter (including oil and gas) after the period of oil genera-tion,wet gas originated from E1-2b source rocks.关键词：同位素;微生物;天然气;油田水;三水盆地595|580|0更新时间：2023-05-30
- 摘要：The oil and gas pools of the Lower Jurassic Daanzhai and Lianggaoshan Formations in central Sichuan are distributed in semi-deep lake and shallow lake facies.The east partis similar to Central Sichuan in this respect.They are two symmetric parts of the same fa-cies zone deposited in the same lake basin.The difference is that exploration level is verylow in East Sichuan.The reservoir beds in the above regions are compact lenticular shell-limestone and sandstone formed by shelly beaches,sand barries and sandbars.Fracturesare well developed in the reservoir beds,formed fracture-lithologic reservoirs.Though thisregion is intensively folded and seriously denuded,the Jurassic reservoir beds inwide-gentle synclines separated from high-steep anticline zones are well preserved.Amongthem,lower and gentle structures,buried structures,the axes of synclines,the affectedzones in the upper end of buried overthrusts and flexural zones are all favourable places toseek for fracture-lithologic trapped hydrocarbon pools.关键词：四川盆地;侏罗系;油气勘探;裂缝性油气藏550|527|0更新时间：2023-05-30
- 摘要：The prodelta slope of the third member of the Oligocene Shahejie Formation in Niuzhuang region,Shandong,is composed of slump slope,proximal gentle slope and distal slope.The slump and the debris flow sediments are well developed on slump slope;theliquefied-flow and the turbidity current sediments developed on gentle slope and the un-complite turbidity assemblage developed on distal slope.The controlling factors for the de-velopment of gravity-flow deposits on prodelta slope are deltaic progradation and the dou-ble-layer structure of the slope.Favourable regions for hydrocarbon enrichment are gentle slope.关键词：三角洲斜坡带;重力流沉积;油气聚集;沙河街组;牛庄洼陷647|485|0更新时间：2023-05-30

- 摘要：The basement nature,the cover facies,the structural feature and magmatic activity in the lower Yangtze Region have presented obvious differentiae in the north and south parts of the region.The reason caused these differences is the existence of south (the Qiantang) and north (the Yangtze) terranes.These two terranes,under went long tectonicevolution,were connected as a unified composite terrane in the end of the Triassic.The Qiantang Terrane is the primary place for hydrocarbon generation and accumulation from Lower Paleozoic;the Yangtze Terrane is the most favourable place for thatfrom Upper Paleozoic (including the Middle and Lower Triassic).The former will be themain target for oil and gas exploration.关键词：下扬子区;复合地体;钱塘地体;扬子地体;构造演化;含油气盆地;油气资源评价;古生界636|545|0更新时间：2023-05-30
