摘要 研究了冻胶堵剂堵水作用大于堵油作用的原因。结果发现 :冻胶体积在水中膨胀 ,在油中基本不变 ,并且冻胶堵剂具有优先进入含水饱和度高的地层的能力 ,主要对水的流通通道产生限制与封堵作用 ,从而导致冻胶堵剂堵水作用大于堵油作用。 This paper has studied the reason for function of water plugging of gel-type water shutoff agent more than its function of oil plugging.The results indicate that the volume of gel-type water shutoff agents expand in water,and keep its volume in oil.And it has the ability to enter into formation with high water-bearing first.It also has the function of limitation and plugging to the passage of water.Thus.the agents result in function of water plugging more than oil plugging.
