摘要
为明确MB斜坡区T1b组储层黏土矿物类型与含油性的关系,指导MB斜坡区优质储层预测,根据岩心观察、铸体薄片、扫描电镜、试油结果及区域成藏条件等进行综合分析.结果表明:MB斜坡区T1b组储层主要发育高岭石、伊蒙混层、伊利石自生黏土矿物;高岭石与储层物性呈正相关,伊蒙混层、伊利石与储层物性呈负相关,油层中相对贫伊利石、富高岭石,水层中相对贫高岭石、富伊利石;近岸水下分流河道/河口坝砂体组合自生高岭石含量较高,物性和含油性较优;远岸孤立河口坝砂体伊蒙混层、伊利石含量较高,物性和含油性较差;AH1、M18、M6一线南北及M003、M006一线以南,共约为500km2的扇三角洲前缘的近岸水下分流河道/河口坝组合相带,井控程度低,为勘探潜力区带.
To clear the types of Authigene Clay Minerals in T1b group and its relations to oil-gas and offer the guidelines to favorable reservoir forecast in MB Slope,this paper analyzes comprehensively the core,slice,lamina,SEM,well test and regional accumulation condition.The results suggest that, there mainly developed three types of authigene clay minerals,namely,K,I/S,I in T1b Group.K has positive correlation with reservoir physical property,while I/S and I have negative correlation with reservoir physical property.Oil layers are relatively rich in K and poor in I,while water layers are relatively rich in I and poor in K.Near-shore distributary channel-estuary dams developed mainly K,whose physical property is favorable,while off-shore estuary dams developed mainly I/S and I,whose physical property is poor.The favorable exploration potential regions is located mainly in Near-shore distributary channel-estuary dams in fan-delta front in south of well AH1-M18-M6,and the south of well M003-M006,covering nearly 500km2.
