摘要：

海上注水开发油田由于受到海洋作业环境与资源限制,注水水源仅能采用有限的地下水以及生产处理污水资源,为此对注入水与储层进行配伍性研究显得尤为重要。通过浅层地下水、生产污水以及混配水与地层岩石的配伍性实验研究,论证不同注入水源对储层的伤害程度,为油田选取最佳清污混配比例提供依据,保障油田在有限的水资源条件下的高效注水工作。

Abstract:

The offshore oilfield water flooding has been restricted by ocean operational environment and resource constraints.The source of injected water can only use the resources such as limited groundwater as well as production treated wastewater.Therefore it is particularly important to study the compatibility between injected water and reservoir bed.Based on the compatibility study on shallow groundwater,production wastewater and mixed compatible water with underground rocks,the reservoir damage caused by different kinds of injection water is discussed.It provides the foundation for selecting the best mixed proportion of clean-polluted,and provides the basis for efficient water injecting work with limited water resources in oilfields.

Key words: offshore oilfield, injection of water, compatibility?
