泡排辅助增压开采工艺应用效果分析

Analysis of application effect of foam drainage assisted pressurized mining technology

针对M区块部分气井增压效果变差的问题,开展泡沫排水采气工艺辅助增压开采试验研究。通过改进泡排流程及起泡剂用量优化调整,经现场应用,试验气井稳产、增产、助排效果显著,优化后的单井雾化消泡流程现场效果较好。试验表明,起泡剂加注量应实行一井一制,根据实际情况不断调整优化。

Aiming at the problem of poor pressurization effect of some gas wells in M Block,the foam drainage gas recovery process was used to assist pressurized mining.By improving the foaming drainage process and optimizing the amount of foaming agent,the test gas wells had a significant effect on stable production,increasing production,and drainage assistance.The optimized single well atomization defoaming process had a good field effect.Test results have shown that the amount of foaming agent should be one well for one strategy,and continuously adjusted and optimized according to actual conditions.
