正理庄油田沙一段碳酸盐岩储层特征及勘探潜力分析
|
摘要
东营凹陷正理庄油田勘探开发已进入中后期,其主要开发层系为古近系沙河街组的沙二段,已进入高含水期,为寻找新的接替层系,通过对该区沙河街组沙一段碳酸盐岩(即生物灰岩)储层特征及分布规律的研究,根据其岩性与电性特征及储层物性特征,探讨其沉积特点,结合该区沙一段生物灰岩储层的大量测井解释资料和试油试采资料,通过三维地震的精细构造解释,对该区沙一段碳酸盐岩储层进行了潜力分析,提出了较为有利的滚动勘探目标。
The exploration and development were at mid-later stage in Zhenglizhuang Oilfield of Dongying Sag,its main development layer was Es2,and entered into a period of high water content,in order to search for new layers,with the research on carbonate reservoir character and distributing rule in the 1st member of Shahejie Formation,its sedimentary characters were discussed based on lithology and electrical property or reservoir physical property.In combination with great number of logging interpretation data and well testing producing information,by means of 3D seismic fine interpretation of carbonate reservoir potential in Es1 is analyzed,and it provides more advanced rolling exploration objects.
