- 摘要：Tarim Basin is a large,superimposed basin which had a long evolutional history.The evolution can be divided into seven stages,three tectonic cycles of the Proterozoic,Paleozoic and Meso-Cenozioc.Eight prototype basins were superimposed and formed in the central and marginal areas of the basin:Middle Proterozoic-Paleozoic half-graben rift basin,passive continental marginal basin,back-arc fore-land basin,epicontinental sea basin and Meso-Cenozoic back-arc foreland basin,collided foreland basin and reactived collided piedmont basin.Eight hydrocarbon-bearing formations of marine,continental, marine-continental alternative facies(Pt2-Pt3,ε-O,S-D,C-P,T-J,K2-E,N1)were deposited.The basin can be divided into eight structure-depression superim posed regions such as central back arc rift-depressed region,northwest passive continental margin-collided foreland depressed region,north pas-sive continental margin-collided foreland-collided piedmont-collided reactive piedmont depredssed re-gion,northeast passive continental margin-collided foreland depressed region;southeast and southwestback arc foreland-collided piedmont-collided reactived piedmont depressed regions;the collided de-pressed regions of the east and west ends.Four depressed belts,thirteen fault-uplifted and overthrust-folded belts formed in the former six depressed regions.The Tarim Basin is rich in hydrocarbon re-sources and central rift depressed region is especially the first order oil potential area.It is estimatedthat it has the largest potential reserves among the basins in China.In addition,there is geological condi-tion to form inorganic gas reservoirs in the deep of the basin.Five kinds of roof-like,superimposed 3-D hydrocarbon resources are formed in the basin and enriched hydrocarbon zones are as many as 10.These zones are the targets for seaking big,huge even super oil and gas fields.关键词：塔里木盆地;含油气盆地;板块演化;盆地演化;盆地类型;油气聚集带575|445|0更新时间：2023-05-30

- 摘要：The recongnization of this paper is based upon the geological and geophysical studies of the China seas and their adjacent regions in the past 30 years.The China mainland was developed from some continental cores existing in Pantha lassa and unit-ed as a whole in the Late Paleozoic.The tectonic evolution of the China seas is closely related to the in-teractions among Eurasia,Pacific and Indian oceanic lithosphere plates.It can be divided into 5 stages:1)An ∈,the continental cores formed and developed into blocks or cratons;2)Pz,blocks gradually united as a whole;3)T3-K1,the China mainland was strongly compressed and remaked;4)K2-E2,the margins of plates converged and the interior of the eastern part of Eurasian plate spreaded;5)After E33,the subduction occurred at the margin of Eurasian plate and its interior was widely subsided,and formed today's feature of the China seas.关键词：中国海;大地构造;构造演化;大陆架;海洋地质635|406|0更新时间：2023-05-30

- 摘要：Geology of petroliferous basins is a new course proposed by the authors to establish.The present-day research in petroleum geology and the oil and gas prospecting have proved that the sedimentary basins are the foundation units in which oil and gas generate,migrate and accumulate.It has also been proved that to study oil and gas generation,migration,reservoirs,traps,and cap rocks in a basin isolated-ly,and to describe and classify oil and gas accumulation simply can not meet the need of hydrocarbon prospecting.So it is necessary to regard the study of the geology of petroliferous basins as a systematic engineering that all kind of factors are connected with each other.This systematic engineering may be divided into several subsystems as follows:1.Background sys-tem.2.Evolution and deformation system.3.Sedimentary system.4.Hydrodynamic system.5.Thermaisystem.6.Oil and gas system.7.Reformation system.At last,all the achievements in researchof the above subsystems will be synthesized and summarized.Only in this way,the systematic engineer-ing of the petroliferous basins can be a complete system.关键词：含油气盆地;含油气盆地地质学;盆地演化;系统工程;油气资源评价582|438|0更新时间：2023-05-30
