摘　　要：杜66区块已经进入开发中后期,目前主要任务是对储层发育带进行剩余油挖潜,因此对储层的精细刻画变得越来越重要。通过"X"衍射等实验分析手段,对其层系岩石特性及矿物特征进行分析;同时通过钻井及测井手段对区域砂体厚度进行统计,探寻优质储层的主要发育位置。研究结果显示,杜66区块储层砂体,一般为(30～50)m,岩性以不等粒砂岩为主,次为细砂岩、粉砂岩,分选较差,平面上物性变化受相带控制,两侧油层物性较差,优质储层主要发育在西北部。Du 66 blocks into the later development stage, maining oil, reservoir fine portrait of becoming increasingly the main task of reservoir development, with the re- important. The ＂ X＂ diffraction experiment analysis tools, rock properties and mineral characteristics of the strata ; regional sand thickness by means of drilling and log- ging statistics, explore the phylogenetic position of the high quality reservoir. The study results show that Du 66 blocks of reservoir sand bodies, usually （30 - 50） m, the lithology ranging from grain sandstone, for fine-grained sandstone, siltstone, poorly sorted, plane changes in physical properties of phase with control, both sides of the reservoir in poor quality reservoir development in the northwest.
