姚店油田W147区块开发特征分析及注水方案调整

Analysis of Development characteristics and Adjustment of Water injection Scheme in W147 Block of Yaodian Oilfield.

利用研究区内钻井、测井资料、岩心分析报告以及物性等资料,通过岩心相标志、测井相等分析,依据“寻找标志层、沉积旋回、邻井追踪、地层等厚”原则,对姚店油田延长组长6油层组进行了地层划分与对比、储层沉积相和砂体的展布规律、储层物性特征及其非均质性等研究,结合研究区的生产动态资料,对研究区开发现状、累计产油、综合含水、产量递减规律等等开发参数进行分析,确定下一步周期注水调整方案。

using drilling, logging data, core analysis report and physical property data in the study area, through core facies mark and logging equality analysis, according to the principle of "finding marker layer, sedimentary cycle, adjacent well tracking, formation thickness", this paper studies the stratigraphic division and correlation, distribution law of reservoir sedimentary facies and sand body, reservoir physical property and heterogeneity of Chang 6 oil formation of Yanchang formation in Yaodian oilfield. Combined with the production dynamic data of the study area, the development parameters such as development status, cumulative oil production, comprehensive water cut and production decline law are analyzed, and the next cycle water injection adjustment scheme is established.
