HR8902、HR8903助排增油剂是人工合成的石油磺酸盐类表面活性剂。通过室内评价研究，其主要性能是：与原油和水具有良好的配伍性，能降低其界面张力和表面张力；化学剂的性能稳定，在200～300℃的高温作用下性能基本不变。同时这两种表面活性剂具有改变油层润湿性，降低油层中束缚水饱和度和残余油饱和度，提高驱油效率的作用。据已投入HR8902、HR8903现场试验的174口井统计，应用合成磺酸盐助排增油剂取得了较为显著的增油助排效果。
HR8902, HR8903 help row by oil agent is a synthetic petroleum sulfonate surfactant. Through the indoor evaluation research, its main properties are: good compatibility with crude oil and water, can reduce the interfacial tension and surface tension; chemical properties of stable, at 200 ~ 300 ℃ under the action of high temperature properties remain unchanged. At the same time, these two surfactants have the effect of changing the oil wettability, reducing the irreducible water saturation and residual oil saturation, and improving the oil displacement efficiency. According to statistics of 174 wells that have been put into field trials of HR8902 and HR8903, the application of synthetic sulfonate to assist the increase of oil production has achieved significant effect of increasing oil production and drainage.
