摘要： 通过对国内外一百多种表面活性剂的初步筛选，发现两性表面活性剂HTHS-1与塔中402CⅢ均质段的油藏条件有良好的配伍性，并对其进行了性能评价。结果表明，两性表面活性剂HTHS-1热稳定性较好，抗盐能力较强，在110°C、矿化度11.5×104 mg/L、钙镁离子含量 7 654 mg/L的条件下，质量分数为0.05%~0.07%的HTHS-1老化30 d前后界面张力均保持在10-2 mN/m数量级；乳化能力较好，略微减小了岩石的亲水性；静态吸附量较大，且油砂上的吸附量大于净砂上的吸附量；达到动态吸附饱和所需时间较长，在天然岩心上的动态滞留量为0.507 mg/g，远小于静态吸附量。

Abstract: In this paper, over 100 surfactants at home and abroad are preliminarily screened. It is found that the ampholytic surfactant HTHS?1 is of good compatibility with the target reservoirs in Tarim basin. The performance evaluation indicates that this surfactant is characterized by goog thermal stability and strong salinity?tolerant capability. In the conditions of 110°C, salinity of 11.5×104 mg/L, Ca2 + and Mg2+ contents of 7 654 mg/L, the interfacial tension of the HTHS?1 with mass fraction of 0.05%~0.07% can remain by 10?2 mN/m in order of magnitude during the aging time of 30 days. Its good emulsification may slightly decease wettability of the rocks, and its static adsorption is large, and that on the oil sand is higher than that of the clean sand. Also, it takes a long time to achieve dynamic adsorption saturation,with the dynamic retention of 0.507 mg/g, much less than the static adsorption
