摘　　要：针对油房庄长1油藏地层水矿化度较高,渗透率低,粘土矿物含量高,剩余油饱和度较高,水相渗透率低的特点,制备了表面活性剂/缩膨剂体系,确定了最佳配方:表面活性剂加量0.5%,缩膨剂JC-931加量0.1%。评价了该体系的性能,结果表明,该体系与地层流体具有良好的配伍性,耐温耐盐性,界面张力稳定性,与油房庄长1油样间界面张力可达10-2mN/m数量级。A surfactant/swelled clay shrinking agent（SSCSA）system for depressurization and augmenting injection was compounded for Youfangzhuang Chang - 1 reservoir with the characteristics of high salinity in formation water,low permeability, high clay content, high remaining oil saturation, and low water phase permeability. The optimum composition was determined as follows：addition amount of surfactant 0.5% ,swelled clay shrinking agent JC- 931 0.1% .The resuh of evaluation on the system performance showed that it had good compatibility with formation fluids, good salinity resistance,stable interfacial tension. The dynamic interfacial tension between the flooding system and Youfangzhuang Chang- 1 oil sample might reach to 10^-2 mN/m.
