辽河油田欢127块重力热管现场试验效果分析

摘要

Huan 127 block in Liaohe Oilfield' s cycle production decrease seriously. Putting the gravity heat pipe technology into the process of this block' s heavy oil exploitation is another new method of heating well' s chamber. Through the comparison of the data of Huan 127-26-34 well and the adjacent well' s one production cycle. while before and after application of gravity heat pipe, it reach conclusion that the wellhead fluid temperature with the gravity heat pipe is from 8℃ to 10℃ higher than that conventional well which without gravity heat pipe 's temperature. it can achieve the desired effect of heating well' s chamber effectively.%辽河油田欢127块周期产量递减严重.将重力热管技术引入到该区块的稠油开采过程中,是井筒伴热的又一新的方法.通过对欢127-26-34井以及与相邻井次应用重力热管前后一个生产周期的现场试验数据对比,可得出应用重力热管后该试验井的井口出液温度比常规生产井井口出液温度提高8℃-10℃,有效地达到了预期的井筒伴热效果.
