曙光油田杜66区块储层物性及分布特征评价

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。

Elsie 66 blocks of reservoir properties and the distribution characteristics of the dawn of the oil field evaluationanalysis

Du 66 blocks into the later development stage, the main task of reservoir development, with the remaining oil, reservoir fine portrait of becoming increasingly important. In this paper, the "X" diffraction experiment analysis tools, rock properties and mineral characteristics of the strata; regional sand thickness by means of drilling and logging 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.
