摘要
在采气过程中加入高温泡沫排水剂有利于降低地层水表面张力及井筒液柱密度 ,改善水气流动状态 ,达到排水采气的目的。通过一系列室内试验筛选出适合江苏盐城气田气水共产井的高温泡沫排水剂。实践证明 ,Ych高温排水剂能保证气井连续排液 。
During the period of gas production, adding High Temperature Foam Drainage Agent(HTFDA) can reduce the surface tension of formation water and well bore fluid density, improve the flowing state of water and gas, and finally achieve the goal of drainage and gas production. In this paper, the HTFDA,called YCH, which is compatible to the gas water producing well in Yanchen Oilfield, is chosen by a serious of laboratory experiments. The practices proved that YCH ,the HTFDA,ensure gas well discharge liquid continuously and production normally.
