摘　　要： 在抽油机井提拉式细分层找、堵水技术已有的找水和堵水方法的基础上,研究出了一种新的找水、堵水技术,它采用Y445型丢手封隔器、Y341型自验封封隔器、弹簧压缩式找水开关等工具组成井下丢手管柱,封隔井下油水层位;抽油杆与控制器组成的控制杆柱下入到丢手管柱内,控制杆柱上部与杆式泵的进油孔相连。通过上提、下放抽油杆可以改变找水开关的工作状态,实现找水与堵水管柱的一次完成。 Rod-pulling and running water detection and plugging technology is a new one which is base on the previous method of water detection and plugging. It uses release packer Y445, self--checked packer Y341 and spring compressed water detection switch to constitute the downhole release string, then to shutoff stratums. The control rod string which is consisted of pumping rod and controller is tripped into the release string. The upside of it is a joint with the standing valve of the rod pump. The working stage of water detection switch can be changed by pulling and running of pumping rod, then water detection and plugging is completed at one time.
