油井自动分层找堵水开关设计及试验
|
摘要
自动分层找堵水开关用于高含水油井的分层作业,实现找水和堵水的功能。设计一种压力平衡式开关,开关在打开和关闭时不受外界压力影响。室内压力和温度试验以及现场应用证明,开关动作可靠,可实现分层找水、堵水作业,满足现场生产需要。
Auto layer switch is used in high water cut oil well for detecting and blocking water. A type of axial force balance switch was designed, which was independent of peripheral pressure. According to the lab test of pressure and temperature and field application, the results show that the switch has the ability to detect and block water reliably and it meets the needs of the field production.
