  复合盆地
     There are currently three main regions of natural gas exploration in China, including foreland basins in west-central China, three large cratonic composite basins (Sichuan basin,Ordos basin and Tarim basin) ,and offshore rift and continental margin basins. The study shows that the most prolific regions in China are those basins and depressions which have dominantly been reservoired and finalized in late and super-late periods.
     目前中国天然气勘探的 3个主要领域 :中西部前陆盆地、三大克拉通复合盆地 (四川、鄂尔多斯、塔里木 )以及近海的裂谷、陆缘盆地 ,表明了以晚期、超晚期成藏、定型为主的盆地和坳陷是中国天然气最主要富集地区。

Song Liao Basin located at upper mantle-arching belt of the east part of Europe-Asia plate belongs to the mid-basin of continental crust.When the upper mantle-doming up,it acted as a hot-dome.Plenty of tensile faults were formed subsequently.Song Liao Basin was formed by the controlling of these crust faults.In early stage,it behaved with characteristics of a rift basin,but in middle to final stages,it gradually changed to a New-intracratonie composite basin,the influence of the isostatic adjustment activity of the crust and underthrust of pacific plate.So that the original depression-rift belts evolved gradually to a depressi- on.Although Song Liao Basin is a continental basin,it has a large area of deep-lacustrine deposits with abundant nutrition to form good source rocks,due to action by twice global plate activities during the Middle Cretaceous.The long term geothermal hot current and high geothermal temperature that had controlled the deagenesis and the matomophism of organic matters in the basin,therefore the source beds exhibited lower threshold temperature of oil generation and rapid evolution of oil and a short maturity zone.On the plane,deep lacustrine facies in this depression where the early rift basin coincided with latter depression and its adjacent parts are most favorable for oil accumulation.

松辽盆地属于陆壳中盆地,处于欧亚板块东部的上地幔拱起带上。盆地就是在这拱起的背景上产生热穹窿作用,造成大陆初始张裂,在壳断裂的控制下形成。早期具有裂谷特点,中后期由于地壳均衡调整作用和太平洋板块俯冲影响由原来裂陷地带演化为坳陷,成为新克拉通内复合型盆地。松辽盆地虽是陆相盆地,但在白垩纪中期的两次全球性板块活动控制下,造成大面积富营养深水湖相沉积,为良好的生油岩。由于长时间的高热流、高地温条件控制了盆地的成岩作用和有机变质作用,因而盆地生油层表现出生油门限浅、演化快、成熟相带短的特点。在平面上早期裂谷与后期坳陷相重合的深坳陷深水相及其两侧地带含油最丰富。

China has undergone a complicated history of geological evolution onshore and offshore from Sinian to the Recent, during which period three basic types of oil and gas basins have been formed. 1. Tension basins in eastern China-With the subduction of the Pacific plate under the Eurasian plate, the continental crust in the eastern part of China was subject to regional tension stresses that caused the breakdown, spreading and subsidence of the basement. A series of intraplate rift-subsided basins occurred to the...

China has undergone a complicated history of geological evolution onshore and offshore from Sinian to the Recent, during which period three basic types of oil and gas basins have been formed. 1. Tension basins in eastern China-With the subduction of the Pacific plate under the Eurasian plate, the continental crust in the eastern part of China was subject to regional tension stresses that caused the breakdown, spreading and subsidence of the basement. A series of intraplate rift-subsided basins occurred to the east of Daxinganling-Taihangshan-Yangtze Gorge which are genetically related to the uplifting of the upper mantle. Basins in Bohai Bay, northern Jiangsu, southern Yellow Sea and Jianghan are of the polycyclic rift-subsided type, while those in Songliao, Nanyang-Miyang and Beibu Bay are monocyclic. The East Sea basin and the west Taiwan basin are continental marginal basins (back-arc basins) included in the west Pacific trench-arc-basin system. Basins in the mouth of Pearl River and in the Yingge Sea are located along the northern divergent margin of the spreading plate in the South China Sea. 2. Oil and gas basins in central China-Located in the transition zone between the Pacific plate belt and the Tethye-Himalaya tectonic belt, these basins grew up under the influence of both. The Shanganning basin and the Sichuan basin are intraplate polycyclic depressions and the Chuxiong basin is monocyclic, trending NNE and NS. Under the eastward thrust of the Tibetanwest Yunnan section, the western margin of these basins formed a center of depressions in the later stage. 3. Oil and gas basins of the compressional type in western China-The northward push of the Indian plate brought about gradually 4 collision-compression zones from the Himalayas to the Altais, followed by a basinal subsidence on a large scale. The large oval-shaped composite basins in Dzungari, Tarim, Tsaidam and northern Tibet were formed in these zones. In the downthrown blocks of the thrust fault zone of Tienshan, Kunlunshan and Chilianshan, there are piedmont basins located in Wusu, Kuche, Yecheng, Jiuquan and Minlou. And Tulufan is an intermontane basin.

中国含油气盆地的基本构造类型有三种: 1.中国东部含油气盆地——拉张型盆地。在大兴安岭—太行山—长江三峡以东分布有一系列板内断陷—拗陷盆地,其成因机制与上地幔的隆起有关。如渤海湾、苏北、江汉等盆地为多旋回的断陷—拗陷盆地。珠江口是南海扩张盆地的北部陆壳边缘断陷—拗陷盆地。 2.中国中部含油气盆地——过渡型盆地。鄂尔多斯和四川盆地为板内多旋回拗陷盆地。 3.中国西部含油气盆地——挤压型盆地。准噶尔、塔里木和柴达木为碰撞挤压带之间的大型卵形复合盆地。乌苏、库车、酒泉和民乐等盆地为山前拗陷盆地。吐鲁番为天山山间盆地。

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 thecontinent 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...

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 thecontinent 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.

西太平洋含油带是一个纵贯全球,以湖相沉积为主的油气聚集带。它的形成与太平洋板块和古太平洋息息相关。自西向东依次为克拉通内坳陷盆地、新克拉通内坳陷盆地、大陆裂谷盆地、陆缘断陷盆地和岛弧盆地。具油气意义的主要为前四类,与其相应的湖泊大体为四类:近内陆坳陷湖泊、近海洋坳陷湖泊、近海洋断陷湖泊和陆缘断陷湖泊。湖盆发育经历了断陷、断坳和坳陷三个阶段。每个阶段持续的时间、规模和性质因盆地类型的不同而不同。由此也决定了生储层和油藏类型随湖盆类型的不同而变化。
