Its multi cyclic tectonic and sedimentary evolution results in five series of hydrocarbon source rock formations--Carboniferous, Permian, Upper Triassic, Middle lower Jurassic, and Lower Tertiary, correspondingly forming five petroleum generation systems, of which the Permian and Middle lower Jurassic petroleum generation systems are the most important with the highest exploration degree. Hydrocarbons are controlled by basin structure as follows: 1) Hydrocarbon accumulations are controlled by the structural styles of paleo uplifts, paleo overthrust belts and contorted anticline belts formed in multi cyclic tectonic movements; 2) Important pathways for long distance lateral and vertical migration are provided respectively by unconformities and faults; 3) The pool forming characteristics of the Permian petroleum system are controlled by paleo structure; 4) The pool forming characteristics of Jurassic and Tertiary petroleum system are controlled by recent structures.展开更多

China contains abundant oil shale resources, ranking fourth in the world, with ca. 7 254.48 x 108 t within 24 provinces, including 48 basins and 81 oil shale deposits. A- bout 48% of the total oil shale resources are concentrated in the eastern resource region, with a further 22% in the central resource region. 65 % of the total quantity of oil shale resources is present at depths of 0-500 m, with 17% of the total resources being defined as high-quality oil shales yielding more than 10% oil by weight. Chinese oil shale resources are generally hosted by Mesozoic sediments that account for 78% of the total re- sources. In terms of the geographical distribution of these resources, some 45% are located in plain regions, and different oil shale basins have various characteristics. The oil shale resources in China represent a highly prospective future source of hydrocarbons. These resources having potential use not only in power generation and oil refining but also in agriculture, metal and chemical productions, and environmental protection.展开更多
