摘要
克拉玛依石油磺酸盐与安庆石油磺酸盐是有代表性的两种国产石油磺酸盐 ,前者由新疆原油磺化中和制得 ,后者是以催化裂化馏分油为原料经磺化中和制得。笔者应用1HNMR和元素分析的方法测定了这两种石油磺酸盐的脱磺油 ,从而得到石油磺酸盐亲油基的支化度和芳香度。应用相图和测定Krafft温度的方法考察了该两种国产石油磺酸盐的亲水亲油性 ,由此探讨了该两种石油磺酸盐间发生协同效应的基础。应用绘制界面张力等值图的方法优化了该两种石油磺酸盐的复配 ,筛选了针对不同试验区块油、水及温度条件的表面活性剂驱油配方 ,验证了该两种石油磺酸盐之间的正协同效应。
Kelamayi petroleum sulfonate and Anqing petroleum solfonate are two typical Chinese petroleum sulfonates formulated respectively from Kelamayi crude oil and FCC distillated by sulfonation. The degree of branching and aromaticity of the oleophylic groups in these two desulfonated oils were obtained by means of 1H NMR and element analysis. The comparison of the hydrophile-lipophile abilities of the two petroleum sulfonates were conducted based on the analysis of the phase diagram of sulfonate-n-heptane-iso-propanol system and the measured Krafft temperature, and the syneregism between the two petroleum sulfonates to attain a minimum interface tension was also discussed. Interfacial tension isographs were worked out to help select the optimum complex formulation of the two petroleum sulfonates. As for different test area situations (oil, water, temperature, etc.), the optimum surfactant flooding formulations were screened out and also used as an indication of the synergism between the two petroleum sulfonates.
