摘要
文章针对浅层低渗透油藏压裂水平缝水平井开发过程种出现的产量递减快,能量补充技术缺乏,水窜治理技术欠缺的问题,开展实施邻井注水补充能量的可行性分析与设计优化研究.首先对目标油藏目前实施的水平井邻井注水补充能量实例的实施情况与效果及存在问题进行剖析,然后综合油藏工程与数值模拟技术对邻井注水补能过程中的关键因素及其作用规律进行了研究;最后确定了该技术实施的原则与技术政策.
Abstract
Aiming at the problems of rapid production decline,lack of energy supplement technology and lack of water channeling control technology in the development of fractured horizontal wells in shallow low permeability reservoirs,the feasibility of implementing water injection to supplement energy in adjacent wells and the research of design optimization are analyzed.Firstly,the implementation,effect and existing problems of the example of water injection to replenish energy in adjacent wells of horizontal wells in the target reservoir are analyzed,and the key factors and their action rules of water injection to replenish energy in adjacent wells are studied by combining reservoir engineering and numerical simulation technology.Finally,the principles and technical policies for the implementation of this technology are determined.
