摘　　要：采用定量计算方法 ,表征了科尔沁油田交 2断块区九佛堂组 ( J3 jf)下段三类主要成岩作用 ,评价了各类成岩作用强度 .根据储层成岩、岩相发育特征及地下流体的不同性质 ,总结出了该区三类成岩储集相类型 :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 .By using the quantitative calculation method, the quantitative characterization of three types of diagenesis in this region was carried out. The intensity of each type of diagenesis was evaluated. Synthesizing reservoir diagenesis, lithofacies development characteristics and the differences in underground fluid property and the types of diagenesis reservoir facies were summarized. Three types of diagenesis reservoir facies are put forward, they are 1) strongly compacted and mixed base-supporting fine-siltstone facies; 2) strongly carbonate-cemented sandstone facies; and 3) unstable mineral-corroded diagenesis reservoir facies is most favorable for reserving oil and gas.
