枣园油田自来屯地区孔一段储层成岩作用及其对开发效果的影响

THE RESERVOIR DIAGENESIS OF THE FIRST MEMBER OF THE KONGDIAN FORMATION IN THE ZILAITUN AREA OF THE ZAOYUAN OILFIELD AND ITS INFLUENCE ON THE DEVELOPMENT EFFECTIVENESS

本文针对枣园油田自来屯地区孔一段油藏开发效果差的实际情况,研究储集层砂岩岩矿特征、成岩作用及其对储集性能的影响、粘土矿物及储层结构模型与储层潜在敏感性及油层损害的关系,提出了油层保护措施。

In regard to the poor reservoir development results of the First Member ofthe Kongdian Formation, in the Zilaitun area, Zaoyuan Oilfield, the authors havestudied the rock and mineral characteristics of the reservoir sandstone, its diagen-esis and the influence of diagenesis on the reservoir properties as well as therelations of ulay minerals and reservoir structural models to the potential reser-voir sensitivity and oil bed damage. Based on these,the authors put forward somemeasures to protect oil beds,
