摘要: 研究了石油磺酸盐/正戊醇/水的三元体系和石油磺酸盐/癸烷/正戊醇/水的拟三元体系相图中的液晶区域,揭示了不同组分对液晶区域大小的影响以及液晶的流变性和液晶的结构.在三次采油中,用六角状溶致液晶体系代替三元复合驱体系进行化学驱油,虽然驱油效率更高,但需要进一步降低液晶驱油体系的成本.

Abstract: The phase diagram of the petroleum sulfonate/pentanol/water ternary system and petroleum sulfonate/pentanol/decane/water quarternary system have been established at 25 ℃. 2H NMRspectroscopy and rheological method have been used to determine the structure which is the hexagon lyotropic liquid crystal. The results show that the areas of the liquid crystal become gradually small with the contents of decylane under a certain temperature 25 ℃. Furthermore, the lyotropic liquid crystal systems are used in place of alkaline/surfactant/polymer complicated system for ternary oil recovery. The coreflood test in the laboratory of the liquid crystal system resulted in a greater recovery of crude oil as compared to ASP(alkaline, surfactant and polymer) flooding system.

Key words: Lyotropic liquid crystal, Oil recovery, Phase diagram
