对鄂尔多斯盆地、四川盆地、塔里木盆地、渤海湾盆地、中下扬子区及滇黔桂地区海相残留盆地的油气成藏系统特征进行了讨论,据此总结出中国主要海相残留盆地油气成藏系统的诸要素与盆地所处大地构造位置、所经历的构造演化历史密切相关,具有以下特征:原型盆地的构造沉降作用控制主力烃源岩的类型与分布;受原型盆地构造演化旋回控制形成三类有效生储盖组合;后期构造作用控制残留盆地晚期生烃中心;加里东期、海西期、印支期形成的继承性大型古隆起是主要油气运移指向区;古生界生烃区的生烃高峰期与圈闭形成期必须形成有机的配置;后期构造改造适中,既要有适当挤压隆升,形成必要的储集空间、圈闭和运移动力,使油气富集,又要不破坏油气藏;在经历后期构造改造后,盆地的晚期生烃及晚期油气运移受改造后的构造格局控制。
The characteristics of hydrocarbon accumulation systems in the Ordos Basin, the Sichuan Basin, the Tarim Basin, the Bohai Bay Basin, the Middle-Lower Yangtze Region and the marine residue basins in the Yunnan-Guizhou region are discussed. Based on this, the hydrocarbon accumulation in the major marine residual basins in China The elements of the system are closely related to the tectonic evolution history of the tectonics and tectonic evolution experienced by the basin and have the following characteristics: The tectonic subsidence of the prototype basin controls the type and distribution of the main source rocks; the tectonic evolution of the prototype basin controls the formation of three And the late tectonism controls the late hydrocarbon generation center in the residual basins. The inherited paleo-paleo-uplift formed during the Caledonian, Hercynian and Indo-Chinese epochs is the major oil and gas migration direction area. The Paleozoic hydrocarbon generation area The hydrocarbon generation peak and trap formation period must be formed organic configuration; post-structural reconstruction moderate, it is necessary to have the appropriate extrusion uplift, the formation of the necessary reservoir space, traps and migration of power, so that oil and gas enrichment, and Or destroy the oil and gas reservoir. After the late tectonic transformation, the late hydrocarbon generation and late hydrocarbon migration in the basin are controlled by the altered tectonic structure.
