低渗油藏水驱合理开发技术政策界限研究

摘要

Through analysis of the water injection development situation in low permeability sandstone reservoirs,taking Y reservoir as an example,aiming at the problem in further tapping the potential of the oilfield in the later stage of high water cut development,main development indexes of Y reservoir were analyzed by using reservoir engineering,fine seismic interpretation and numerical simulation methods,the reasonable technology policy limit of development was determined in order to further improve the development effect of the oilfields and get high water flooding yield and economic benefits.%通过对低渗透砂岩油藏目前注水开发情况分析,以Y油层为例,针对高含水开发后期油田的进一步挖潜所面临的问题,运用油藏工程、精细地震解释、数值模拟等方法,对Y油层的主要开发指标进行分析研究,确定合理的开发技术政策界限,为进一步改善油田开发效果、获得尽可能高的水驱采收率和经济效益提供理论依据.
