中国大陆是由若干大小不等的克拉通与不同时代的造山带组成的拼合体,在显生宙经历了古生代陆洋分化对立阶段、石炭纪—二叠纪软碰撞转化阶段和中、新生代盆山对峙发展阶段,从而形成了陆上3类叠合型盆地:即克拉通与前陆叠合、断坳叠合及残留与新生盆地的叠合。长期继承发育的大型叠合盆地拥有丰富的油气资源,富生烃坳(凹)陷则控制了盆地内油气资源的主体。多旋回发展与多类型生烃母质富集决定了陆上富油油气。大型坳陷湖盆的振荡发育与湖水频繁进退造成生、储油层的间互与侧变接触,形成了3种连片含油类型。古地温场是影响中国陆上油气藏形成与分布的关键因素。强烈的后期改造影响到油气的分布,并增加了勘探难度。
China is composed of a number of cratons of different sizes and different age orogenic belts in the assembly, experienced in the Phanerozoic Paleozoic continental differentiation opposition phase, the Carboniferous - Permian soft collision transformation stage and the Mesozoic, Cenozoic There are three types of superimposed basins in the terrestrial: the superimposition of craton and foreland, the combination of fault-depression and residual and the new basins. The long-term succession and development of large-scale superimposed basins have abundant oil and gas resources, and the rich-hydrocarbon depression (depression) controls the main oil and gas resources in the basin. Multi-cycle development and enrichment of multi-type hydrocarbon generation parent hydrocarbon determine oil-rich onshore. Large-scale depression lacustrine oscillation development and frequent lake water caused by birth, reservoir interaction between each other and side by side, forming three contiguous oil type. Paleogeothermal field is a key factor that affects the formation and distribution of onshore oil and gas reservoirs in China. Strong post-transformation affects the distribution of oil and gas and increases exploration difficulty.
