摘要/Abstract

摘要： 塔里木是一个既富油也富气的盆地,它发育寒武系、中上奥陶统、石炭系和三叠-侏罗系等多套烃源岩,这是油气勘探的基础,也决定了其具有多期成藏的特点。分析认为,由于晚期生成的油气经历的破坏运动较少,对于成藏更具有实际意义;早期形成的油藏有破坏也有保存,油气可以在深部保存的必要条件是高压低热流;盆地中发育的五套储盖组合,为大型、特大型油气藏的形成提供了不可缺少的条件。此外,结合具体地质条件讨论了库车油气系统、塔北地区和塔中地区的油气勘探方向。

Abstract: The Tarim basin is abundant both of oil and gas, there developed multiple sets of source rocks such as Cambrian, Middle and Upper Ordovician, Carboniferous and Triassic-Jurassic systems. They are the basis of crude oil prospecting,and formed the characteristics of multi-staged formation of pools. The analysis suggested that as the later- generated-hydrocarbon underwent less destructive influence of tectonic movements, so it benefited favorably on forming of existing pools. While for earlier formed pools, some have been destroyed and some are well preserved. The prerequisites for which deep-buried hydrocarbon could be preserved are high pressure and low heatflow. The five sets of reservoir-caprock assemblages developed in the basin have provided essential conditions to form large and super-large oil-gas reservoir. Besides, combined with concrete geologic conditions concerned, the paper discussed the exploration orientation for Kuche petroleum system, Tabei region and Tazhong region.

Key words: Tarim basin, source bed, reservoir preservation condition, oil and gas exploration
