摘要: 注入水与储层岩石和流体具有良好的配伍性,是油田注水开发(特别对于中低渗透砂岩储
层)过程中“注够水、注好水”的前题条件,其配伍的程度直接影响注水井的吸水能力。因此,必须根据配伍性要求,对注入水的水质进行规范。文中从注入水损害地层机理出发,阐述了评价注水水质指标的技术思路,提出了配伍性注水水质方案的决策思路,并研制了相应的配伍性注水管理软件,对提高配伍性注水的操作与管理水平具有重要的指导意义。

Abstract: Keeping injection water well compatiable with rocks and fluids in sandstone oil bears(especially for mid-and low-permeability is very important for reservoir pressure maintenance during waterflooding, and the extend of com-patibility is directly involving with the well injectivity. The water quality specifications must be limeted in a rea-sonable range to control formation damage, the specification evauation and determing strategy has been atudied in
this paper, a useful software has also been made to strenously manage the water injection system.
