摘要
吉木萨尔凹陷具有充足的油源和良好的运聚条件。通过对吉木萨尔凹陷进行构造演化,油气成藏特征分析表明:吉木萨尔凹陷构造演化分为6个阶段,其主要成藏期次为侏罗纪中期和白垩纪末期。其中晚海西构造运动,燕山Ⅱ幕和燕山Ⅲ幕构造运动对吉木萨尔凹陷油气成藏具有重要作用。
There are adequate oil and favorable conditions for oilgas migration and accumulation in the Jimusaer sag.Analysis which are Based on the tectonic evolution and reservoir characteristics of the Jimusaer sag show that the tectonic evolution of the Jimusaer is divided into 6 stages,and middle Jurassic and the latest Cretaceous are the main reservoir forming period.The late Hercynian tectonic,The Second Episode of Yenshanian Period and The Third Episode of Yenshanian Period have played important roles for oil-gas reservoir-forming in the Jimusaer sag.
