摘　　要：目的　研究石油磺酸盐对砂岩润湿性的测定方法。方法　采用Washburn方程建立了测定及计算方法。结果　通过相对润湿接触角概念的提出,得到了砂岩 重烷基苯石油磺酸盐水溶液体系润湿性的测定结果。结论　建立的砂岩 石油磺酸盐水溶液体系的润湿接触角测定方法是一简便、准确的方法。石油磺酸盐水溶液浓度的变化将对砂岩的润湿性质产生明显影响。AimStudying the method of measuring the wettability of sandstone-petroleum sulfonate system. MethodsThe method of measuring and calculating the wettability is established by using washburn equation. And the method of purifying industrial heavy alkylbenzene petroleum sulfonale is also presented. ResultsThrough the presentation of the concept of relative wetting contact angle of the system, the measuring result of the wettability of sandstone-heavy alkylbenzene petroleum sulfonate system is got. ConclusionThe method of measuring the wetting contact angle of the sandstone-alkebenzene petroleum sulfonate aqueous solution system presented in this paper is simple and convenient and accurate. The concentration of the aqueous solution system has outstanding effects on the wettability of sandstone.
