摘要
根据碎屑成分、成岩矿物组合、填隙物成分、成岩作用类型及孔隙演化等特征,将苏里格气田盒8段储层划分为4种成岩相,分别为石英次生加大成岩相、净砂岩弱压实弱胶结相、不稳定组分溶蚀成岩相和杂砂岩强压实成岩相。在此基础上,通过自然伽马、声波时差、密度及深浅侧向测井与成岩相的对应关系,建立相应的定量化测井识别模式。
According to clastic constituents,diagenesis mineral composition,interstitial matter,diagenesis type and pore evolution characteristics,H8 reservoir in Sulige Gas Field was divided into four diagenetic facies types and three diagenetic facies combination. By the analysis of the relationship between diagenetic facies and electrofacies,logging curves favorable for identifying diagenetic facies are summarized,which are SP,AC,DEN,combination of RLLS and RLLD. And their quantitative logging curves modes are established.
