摘要:

从赛汉塔拉凹陷的形成、演化及构造特征出发,探讨了凹陷构造发育的石油地质特征,阐述了凹陷油气赋存、断裂与油气的关系,指出:断裂活动的摩擦热以及岩断裂的火山喷发活动使该区地温梯度升高,有利于有机质转化为油气。通过以遥感资料、地球物理(重、磁、电)资料、地球化学资料三者相结合的遥感化探新方法综合分析凹陷的含油气性,评价了各含油气区块的含油气级别,进而明确了有利的含油气远景地区。

Abstract:

According to formation, evolution and structural characteristics of Shaihan Sag, structural development and petroleum geological characteristics of the Sag are discussed, and the accumulation of oil/gas and the relation between fault and oil/gas are descried. It is pointed out that friction heat due to faulting activity and volcanic eruption along the faulty make the geothermal gradient rise in the area, which is favorable for organic matter to transform into hydrocarbon.

Key words: Tectonic transport, Remote sensing, Hydrocarbon potential
