摘要

针对江37 稠油油田蒸汽吞吐开采稠油过程中出砂严重的情况,进行了注表面活性剂降黏驱油室内实验研究。表面活性剂筛选实验表明,FPS-H 分散型稠油降黏剂与江37 稠油油田采出污水具有较好的配伍性,可使油/水界面张力下降到0.05 mN/m,稠油乳化降黏率达到92.1%。驱油实验结果表明,FPSH降黏剂驱最佳注入量为0.5 PV,最佳注入速度为1.0 mL /min,注入方式应选择0.5 PV 段塞-后续水驱方式,注入水温度不宜超过50 ℃。

Abstract

Aiming at the serious sand production situation in the process of steam stimulation in Jiang 37 heavy oil field, an experimental study on oil displacement by injecting surfactant for viscosity reduction is conducted. Surfactants screening result shows that a distributed viscosity reducing agent called FPS-H has a good compatibility with produced water from Jiang 37 heavy oil field, the interfacial tension of oil /water could be lowered down to 0.05 mN/m, and the viscosity reduction rate through emulsion could be upped to 92.1%. The optimum parameters of FPS-H flooding, including injection amount of 0.5 PV, injection rate of 1.0mL/min, injection method of 0.5 PV FPS-H plus continuous water flooding and injection temperature ofwater below50℃, are determined in the experimental results of oil displacement.
