摘要
注水是保持地层能量,延缓产量递减,提高开发经济效益的常用方法。江苏油田大部分区块都属于低渗透油藏,由于其本身的低渗透性质,决定了注水存在较大的风险。本文通过对江苏油田低渗透储层孔隙度、渗透率、粘土矿物含量与注水敏感性等资料分析,结合造成现场注水系统腐蚀及地层堵塞的可能因素,重点对低渗透储层的注入水质进行了研究,研究认为注入水与地层配伍不完善是导致低渗透油田注水损害的主要原因,并提出了改善江苏低渗油藏注水开发的建议。
Water injecting is a regular way to maintain the energy of formation and reduce the degree of oil produce and to advance the economic effect of oil field exploitation.Petroleum reservoir in a low permeability have a high risk in its water injecting because of its characteristics in the low permeability.This aeticle mainly research the injecting water quality of jiangsu low permeability reservoir,by means of analyse its porosity、permeability etc.Our conclusion is the bad compatibility between injecting water and reservoir is the main reason which cause the infusion injury to reservoir.So this article research the compatibility in Jiangsu oil field,and suggest some ideas to advance water injecting effect of Jiangsu oil field.
