有机铬类调剖堵水剂室内研究

Laboratory Study on Profile Control and Water-Cut Shutoff Agent of Organic Chromium

对有机铬类选择性调剖堵水剂的性能进行了评价,通过改变该调剖剂的温度、pH值、矿化度,对该调剖剂的抗温性和稳定性进行了综合评价,结果表明该调剖剂适合现场生产需要。通过岩心流动实验,研究了渗透率不同的岩心的堵水情况。研究结果表明:用该调剖剂适时地进行多轮次调剖堵水,能取得控水稳油、发挥高含水期生产潜力的理想效果。

The performances of profile control and water-cut shutoff agents of organic chromium were evaluated. By changing the temperatures, pHs and salinities of the profile control agents, the temperature and stability were evaluated comprehensively. It shows that the profile control agent is suitable for the scene production needs. And through the core flow experiment the water shutoff situations of different permeability cores was studied. The research shows that, if we operate the multi-round profile control water shutoff measures and succeed the rounds of the profile control water shutoff measures timely, we can achieve the desired effect of controlling the water and stabling the oil,displaying the production potential of high moisture content reservoir.
