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50 mg/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20%以上，具有明显地降压增注作用，表现出很好的应用前景。

In order to resolve the problems of high inj ection pressure in the low permeability reservoirs,the CMC,interfacial tension,wettability and depressurization effect of a depressure and augmented inj ection 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.
