摘要: 依据岔路河断陷大量的岩心、薄片、扫描电镜、X衍射等资料, 详细研究了岔路河地区储集层特征及成岩作用类型.按照成岩阶段划分标准, 将成岩阶段分为早成岩A期和B期, 晚成岩A期和B期, 其中晚成岩A期又分为A1和A2两个亚期; 运用BasinMod软件对主要构造部位进行埋藏史和热史的分析, 并结合孔隙演化史的研究, 分析了储层成岩演化过程, 结果显示, 在30Ma以前, 储层以压实和胶结作用为主, 下部的双阳组和奢岭组孔隙度从32%左右下降至15%左右, 上部的永吉组和万昌组孔隙度从32%左右下降至20%左右.在30~10Ma, 各地层都沉降至最大埋深, 较深部的双阳组和奢岭组砂岩中长石大量溶解, 孔隙度增加至18%左右, 为油气储存提供了良好的孔隙空间, 永吉组和万昌组孔隙度变化不大.在充分考虑了岔路河地区的埋藏史、有机质热演化史、成岩作用演化史以及岩石类型与沉积相等影响因素的基础上, 建立了该断陷的3种成岩模式: 冲积扇成岩模式、扇三角洲成岩模式和半深湖-深湖相成岩模式.Abstract: The characteristics and diagenetic types of Chaluhe reservoir were studied in terms of the data of drill cores, slices, scanning electron microscopy, X-ray diffraction.According to the criterion of division, the diagenetic phases are divided into early diagenetic A stage, B stage, and late diagenetic A stage and B stage, and the late diagenetic A stage is divided into A1 stage and A2 stage.By using the software of BasinMode, the burial history and thermal history of the primary structure were analyzed, and combined with the result of porosity evolution history, the reservoir diagenetic evolution was studied.The result is: before 30 Ma, the primary diagenesis was compaction and cementation.The porosity in the formation of Shanyang and Sheling reduced to 15% from 32% approximately, and that of Yongji and Wanchang reduced to 20% from 32% approximately; During the period of 30 Ma and 10 Ma, all the formations had been buried to the deepest depth and the feldspars in the sandstone formations of Shuangyang and Sheling began to dissolve, which caused the porosity to increase to 18%, providing space for the storage of oil and gas; but the porosity unchanged in the formation of Yongji and Wanchang during this period.Three diagenetic modes (alluvial fan, fan-delta, deep and half-deep lacustrine facies) are built in Chaluhe fault depression based on the study of burial history, thermal evolution history of organic, diagenetic evolution history, the rock type and sedimentary facies.
