| 摘 要： | 本文主要是对塔里木盆地库车坳陷东部的依奇克里克构造、克拉苏及吐格尔明三个构造带砂岩储层中包裹体进行了研究。利用包裹体的均一温度、有机包裹体的显微镜荧光特征、气相色谱、激光拉曼的成分分析,重点讨论了依奇克里克构造带成藏条件。通过对研究区储层中包裹体研究结合油气藏的分布特征认为在库车坳陷东部储层物性不是油气成藏的关键因素,封存条件才是控制该区油气能否成藏的决定因素。断层断在地层内部,对成藏有利,而地层产状较直立,断层直通到近地表,油气沿断层向上运移逃逸,包裹体是最好的证据。由储层包裹体温度、荧光特征和成分上的差异显示出在依奇克里克构造带至少有二次油气运移,第一期有机质低成熟时有过少量的油气运移,大量的油气运移是第二期。爆裂法进行群体包裹体气相色谱分析结果,显示出两个高峰区域,两个高峰区分别反应了轻烃与重烃“C”数上的差异,利用了514nm 和785nm两个激光波长,进行了激光拉曼分析,其测试结果显示出,断层开启的样品包裹体中 H_2O 都很高,CO_2含量很低,断层封闭的样品 H_2O 部很低,CO_2含量高,以次来判别储层的封闭条件。

| Abstract: | The high producing gas well situated on Yinan Structural nose zone,Yinan 2 appearing,the lower Jurassic formation could be responsible for one of the much more favourable reservoir in the Yiqikelec area,Kuqa depression of Tarim Basin. Wovertheless,three wells that followed,Yinan 4,Yishen 4,Yinan 4,show less evidence to go along with the view and raise a number of fundamental geologic questions,Whether gas source rocks,fault-structure and reservoir result in the situation the authors set about the reservoir's geologic features and pay close attention to analyzing the organic inclusion of the layer.Based on the research,the paper were clearly illustrate the accumulation and preservation conditions of the lower Jurassic formation in the eastern region of Kuqe depression,which are key factors forming hydrocarbon reservoir. |
