| 摘 要： | 为了对科尔沁油田交 2断块区九佛堂组 ( J3 jf)下段的成岩作用与成岩储集相有一个明确的认识 ,在沉积相研究工作的基础上 ,利用取心井岩心系统观察及各类薄片鉴定 (常规薄片和铸体薄片 )、X-衍射、阴极发光、扫描电镜及电子探针能谱、图像分析等实验分析测试资料 ,对九佛堂组储层成岩作用类型进行研究 ,并实现了定量评价 ;研究结果确定了该区 3类成岩储集相类型 ,即 :杂基支撑强压实细 -粉砂岩相 ,碳酸盐强胶结砂岩相及不稳定矿物强溶蚀成岩储集相 .其中不稳定矿物强溶蚀成岩储集相为最有利于油气储集的成岩储集相类型

| Abstract: | Based on sedimentary facies research, by using core observation and the data of thin section identification (conventional and casting thin section), X diffraction, cathodoluminescence, electronic probe spectrum and image analysis etc., the diagenesis types of J 3jf of Jiao 2 block reservoir are studied and quantitatively evaluated. The types of diagenetic reservoir facies are determined: strongly compacted mixed base supporting fine siltstone facies, strongly cemented carbonate sandstone facies and strongly corroded unstable mineral diagenetic reservoir facies. Among them, the third type, that is, strongly corroded unstable mineral diagenetic reservoir facies is most favorable for reserving oil and gas. |
