探索了用一种特殊的阳离子乳化沥青替代稠油研发的新型油田堵水剂，在中高温、无稠油资源的条件下应用于油井堵水作业的可能。实验研究结果表明，在阳离子乳化沥青浓度20%～40%、90℃条件下，岩心封堵率大于98%，封堵强度大于2 MPa/m，同时能够优先进入高含水层，满足油藏选择性堵水的技术需求。

The probability to use a new kind of cation emulsified asphalt plugging agent to carry out oil well water shutoff in the condition of medium-high temperature and lack of heavy oil was discussed. The results indicate that the plugging rate is more than 98% and the plugging strength is 2 MPa/m or higher in the condition of 90℃ and the cation emulsified asphalt concentration between 20% and 40%. The plugging agent can enter into the layers with high water-cut and reach the technical demand of selective water plugging.
