摘要
根据马岭油田北三区油田水性质 ,结合污水与地层水混合的静态实验结果分析 ,发现污水回注对地层可能引起不同程度的伤害。同时 ,模拟地层条件做岩心流动实验 ,将采出的污水回注到地层与地层水混合后 ,亦会使地层渗透率下降 ,且随着污水含量的增加 ,渗透率伤害程度增大。
Based on experiments, a feasibility assessment has been made for the reinjection of waste water in the No.3 north area of Maling oil field. According to static test on mixed water made of produced water and formation water,waste water reinjection led to the formation damage.Core flow test was conducted by simulating the reservoir condition.The permeability of formation decreased after the reinjection of waste water.The decline of permeability continued after more waste water was reinjected.
