鄯善油田论文：鄯善油田储层特征储集空间沉积相储层分类

1、类【中文摘要】本文研究采用储层地质学、现代沉积学、层序地层学、储层评价及储层反演等理论和方法，以岩心、测井、钻井、测试分析资料为基础，对鄯善油田七克台组和三间房组储层的岩石学特征、成岩作用类型、储集空间特征、沉积体系及储层分类及特征等进行了深入的研究。镜下鉴定资料、录井资料以及岩心资料表明：三间房组上部以中细砂岩为主，下部以中粗粒砂岩及砂砾岩为主。成分、结构成熟度总体较低，储集层孔隙度和渗透率低。七克台组以粉-细砂岩为主,成分结构成熟度低。压实压溶作用、胶结作用是层成岩过程中致密化的主要作用，并伴随有不稳定组份溶解作用、压实压裂作用及构造破裂作用等能够提高孔隙结构组合特征的成岩作用。储集空间类

2、型有原生孔隙，也有次生孔隙及裂缝，层的孔隙类型以次生孔隙和裂缝为主。原生孔隙以残余原生粒间孔为主，次生孔隙主要为粒间和粒内溶孔，以及粒间孔和粒内溶孔的组合。此外还有晶间孔、铸模孔,以及构造缝、微裂缝等。在前人研究基础之上，从沉积构造、沉积韵律及测井相研究入手，对层沉积相和沉积微相进行了划分，分析了层各单砂层的空间展布规律。通过建立储层属性模型，得到了孔-渗关系模型,继而对其粗化后为油藏数据模拟打下基础。通过对善E善油田低渗透储层地质单因素分类，将层油层以好、中、差分为I类、H类、皿类,对研究区452口井进行了油层分类评价。【英文摘要】Byusingthetheoriesandtechnique
