摘要
本次研究基于油田开发后期普遍含水率高的地质现状,针对性采用匹配滤波地震速度谱、河流相储层构型分析、基于岩石物理理论基础的烃类检测方法,分别解决了渤海C油田低幅度构造刻画难、河流相砂体剩余油描述难、储层砂体含油气边界预测难的生产痛点,新增地质储量11150万方,实现了油田滚动扩边、精细挖潜的地质需求.
Abstract
This study is based on the geological situation of high water content in the later stage of oilfield development.Targeted methods such as matched filtering seismic velocity spectrum,analysis of fluvial reservoir configuration,and hydrocarbon detection based on rock physics theory were used to solve the production pain points of low amplitude structural characterization,description of residual oil in fluvial sand bodies,and prediction of oil and gas boundaries in reservoir sand bodies in Bohai C Oilfield.An additional geological reserve of 111.5 million cubic meters was added,Realized the geological requirements of rolling edge expansion and fine potential tapping in the oilfield.
