摘要
介绍了Ⅱ号盐抑制剂在江汉油田采油中的应用情况。现场试验结果表明,在采油井内注入Ⅱ号盐抑制剂,可增加原油产量,延长检泵周期,产生良好的经济效益。
A great deal of oil wells in Jianghan Oil Field contains saturated brine in large quan- tities and was to maintain their production only by injecting fresh water into annuluses to prevent brine from salt precipitation.This trouble problem is solved now by introducing down well salt precipitation in hibitor Ⅱ in 30 mg/l of water produced.The results of field tests in 47 wells totally performed in 3 stages over 9 months are shown to be satisfactory: fresh water injection is reduced,water content of produced liquid decreased,oil production increased,and/or working life of oil pumps enlarged in some or other wells.
