摘　　要：综合应用岩心观察、薄片和扫描电镜及多种化验测试资料,对红岗油田高台子油藏储层成岩作用进行了系统研究,结果表明压实作用、交代作用、胶结作用以及溶蚀作用为储层主要成岩作用类型。胶结作用中胶结物类型主要有粘土矿物、碳酸盐矿物和硅质胶结物三种。粘土矿物中伊利石最多,高岭石和绿泥石其次;碳酸盐胶结物以方解石为主;硅质胶结物主要为石英加大和自生。在总结各类成岩作用特征的基础上,进行了成岩演化研究,确定了研究区储层处于晚成岩A1阶段,得出了成岩作用对储层物性的影响,为储层综合评价提供了重要的依据。by integrating a variety of laboratory test data which contained core observation,thin section and scanning electron microscopy and a variety of laboratory test data,reservoir diagenesis of Gaotaizi of Honggang Oilfield has been systematically studied,The results show that compaction,metasomatism,cementation and dissolution are the main reservoir diagenesis types。 The main cement are three types,which include clay minerals,carbonate minerals and siliceous cement。The content of illite in clay minerals is the highest,thn kaolinite and chlorite are the secondary; The content of carbonate minerals is mainly calcite; siliceous cement are quartz secondary growth and authigenic 。The study of diagenetic evolution has been carried out on the basic of summing up all kinds of diagenesis characters 。The research result determines that the study area belongs to the late diagenetic stage of A1,conclude that diagenesis has an impact on reservoir properties and provide important foundation for the reservoirs of comprehensive evaluation.
