摘要： 针对低渗透油田存在注入压力过高, 在室内一定条件下对一种活性水体系( 降压增注剂) WH - S的临 界胶束浓度、 界面张力、 润湿性及降压效果进行了研究。结果表明, 当 WH - S溶液质量浓度为5 0m g / L左右时, 降低 油水界面张力效果最好。WH - S溶液具有良好地降低油水界面张力、 改变岩石润湿性的作用。降压实验结果表明, 该降压增注剂的降压幅度能达到2 0%以上, 具有明显地降压增注作用, 表现出很好的应用前景。

Abstract: In order to resolve the problems of high injection pressure in the low permeability reservoirs, the CMC, interfacial tension, wettability and depressurization effect of a depressure and augmented injection agent WHS has been studied in laboratory. The results indicated that the effect of reduce oilwater interfacial tension was best when the concentration of WHS solution was around 50 mg/L. WHS solution can be used to reduce the oilwater interfacial tension and change wettability of rocks. Reduce pressure experimental results showed that WHS solution has obvious effect on reducing the pressureand increasing the note and the injection pressure could be reduced by 20%, showing a good prospect.

Key words: Low permeability oilfield,    , Depressure,    ,  Augmented injection,    ,  Interfacial tension,    , Wettability
