摘　　要：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。The synthetic sulfonate cleanup additive is used t0 impr0ve the effect of steam soaking. Laborat0ry studies 0n its solubility,heat-durability, interfacial tension, high-temperature oil displacement efficiency and relative permeability and on emulsifyingoil viscosity reduction have been done. In situ tests which were carried out in early l0O wells sh0w that the synthetic sul-fonate cleanup additive is suitable to be used in fields t0 improve the effect of steam s0aking as a high-temperature resistancechemical additive.
