摘要
枣北油田孔一、二段为主要含油层系。笔者通过储集砂岩的薄片分析、扫描电镜观察和X光衍射分析,对砂岩内粘土矿物的绝对含量,各类粘土矿物的相对含量、产状、形态、垂向分布和演化等特征进行了研究;分析了粘土矿物对油层物性的影响,在油层敏感性试验研究的基础上,对各油层的敏感性强弱进行评价。
The Kong-1 and-2 members are major oil-bearing sequences in the Zaobei OilField. The contents of clay minerals and their manners of occurrence in sandstone havebeen analyzed by means of thin—section analysis, scanning electron microscopy and X-raydiffraction analysis and their vertical distribution and evolution have been studied. The ef-fects of clay minerals on reservoir physical properties have also analyzed. The sensitivity ofvarious reservoirs has been evaluated on the basis of the reservoir sensitivity tests.
