石油磺酸盐合成技术进展

Petroleum-sulfonate synthesis technology progress

石油磺酸盐是一种以石油馏分为原料的合成阴离子表面活性剂,主要用作驱油剂,具有界面活性强,与原油配伍性好以及水溶性好等优点,一直受到广泛重视。石油磺酸盐因原料油组分及分子结构复杂,结构和性能差异大,使得三次采油应用的表面活性剂应满足低界面张力和低吸附量才能达到提高采收率的目的,故开发具有高界面活性和低吸附损失的石油磺酸盐具有重要意义。

Petroleum sulfonate is a kind of synthetic anionic surface active agent with petroleum fractions as raw material. It has drawn widely attention as oil displacement agent owing to strong interfacial activity, good compatibility with crude oil as well as good solubility in water. Due to the complexity of oil raw material composition, molecular structure and composition of petroleum-sulfonate are very complex; thus, structure and performance differ greatly. For application in tertiary recovery, surfactant should meet such requirements as low interfacial tension and low adsorption capacity to achieve the improvement on recovery factor. Therefore, development of petroleum sulfonate with high interfacial activity and low absorption loss is of great significance.
