摘　　要：以X油田减压馏分油为原料,采用SO_(3)气相连续膜式磺化工艺开展驱油用石油磺酸盐表面活性剂中试试验。考察了不同原料油、物料配比、反应温度、平均SO_(3)质量分数、气液摩尔比等因素对石油磺酸盐性能的影响,筛选出了最佳原料油配比,优化出了合理的生产工艺参数,制得了活性含量和界面活性均满足行业要求的石油磺酸盐表面活性剂产品。检测结果表明,通过原料油复配和合成参数优化生产出的X油田石油磺酸盐中试产品,活性物质量分数高达33%以上,能使X油田X区油水界面张力降低到10^(-3)mN/m数量级,为该油田提高采收率用石油磺酸盐表面活性剂的工业化生产提供了有力支撑。The pilot test of petroleum sulfonate surfactant for oil displacement was carried out by using vacuum distillates of X oilfield as raw material and SO_(3)gas phase continuous membrane sulfonation process.The effects of different raw material oils,material ratio,reaction temperature,average SO_(3)mass fraction and gas-liquid molar ratio on the performance of petroleum sulfonate were investigated.The optimal ratio of raw material oilsand the reasonable production process parameters were obtained,and the petroleum sulfonate surfactant product whose active content and interfacial activity meet the industrial requirements was prepared.The test results show that the petroleum sulfonate pilot product produced by the compounding of raw material oils of X oilfield and the optimization of synthesis parameters has a mass fraction of active substance of more than 33%,which can reduce the oil-water interfacial tension in X area of X oilfield to the order of 10^(-3)mn/m,and provides a strong support for the industrial production of petroleum sulfonate surfactant for enhanced oil recovery in this oilfield.
