摘 要: | 中国可分为五大构造区,它们控制了沉积盆地的形成与演化。每一沉积盆地可有单一层次或多层次结构,分别构成一种或多种盆地原型;对两种以上原型盆地组成的叠合盆地,宜用双重分类命名。以印支旋回为界,可分上、下两大油气组合,上部组合约占我国油气资源总量的60—70%,今后仍应是重要勘探对象,同时要大力开展下部组合的勘探。为深入评价盆地的含油性,可建立计算机定量动态模拟系统。

RESEARCH AND ASSESSMENT OF CHINA’S PETROLIFEROUS BASINS |

Abstract: | China can be divided into five major tectonic areas:North(Siberian- Mongolian)continental margin area,North continent and continentalmargin area,South continent and continental margin area,South(Gond-wana)continent and continental margin area,and East(Peri-Pacific)conti-nental margin area(extensional tectonic system was superimposed after late Mesozoic).These sedimentary basins have two different basinal architectures,i.e.single-layered and multi-layered architectures,each of them forms adifferent basin prototype.Double classification nomenclature can be usedfor those superimposed basins that composed of various basin prototypes.Thebasins in China can be classified into 8 different types,they are:intraconti-nental rift/rift valley,continental marginal rift/rift valley,craton-rift,cra-tonic fold-rift,cratonic rise-fold,intra-orogenic depression,foredeep andcraton-foredeep.The Indosinian tectonic cycle,being a turning point,the evolutional andsedimentary histories of the pre- and post-Indosinian are quite different.Thepre-Indosinian is characterized by steable and widespread cratonic cover,mainly composed of marine carbonate platform deposit,and forms the lowergas-bearing series while the post-Indosinian is mainly comprised of conti-nental clastic sediments deposited in isolated,different sized intracontinentalbasins,which constitute the upper oil- and gas-bearing series.The lower gas-bearing series spread in an area of nearly 300?10 |
