摘要
盒8段和山1段是苏里格南合作区块主要开发目的层,也是该气田主力产气层段。从沉积岩石学特征入手,综合应用铸体薄片、扫描电镜、孔渗试验等岩心分析化验资料,利用数理统计方法,对苏里格南区块盒8、山1段致密砂岩储层的微观特征进行了分析研究,并分析其对储层物性的影响。根据岩心分析试验的孔隙度和渗透率将目的层分为3类,其中I、II类储层是研究区开发的优质储层,是增储上产的主要目的层。
He8member and Shan1member are the main development target and the main gas producing section of Sulige field.Starting from the characteristics of sedimentary petrology,the microscopic characteristics of the tight sandstone reservoirs of the He8member and the Shan1member were studied according to the statistical analysis of casting sheet,scanning electron microscopy and core porosity and permeability test data,and the influence of the reservoir microscopic characteristics on reservoir properties was analyzed.Thetarget layers are divided into3types according to the porosity and permeability of cores,I and II types of reservoir are high quality reser?voir,and are the main objective layers to increase and reserves and yield.
