可换向找水开关在找堵水工艺中的应用

Application of Change-over Water Finding Switch in Water Finding and Plugging Technology

找水开关是找堵水技术的关键工具之一,找水开关性能的优劣直接决定着找堵水工艺的成功率。一种新型的找堵水工具,现场施工成功率达到100%。利用这种找水开关与堵水工艺管柱配套使用,可使一趟管柱实现堵水功能的同时进行找水,既简化了施工工艺,又节约作业费用。

Water finding switch is one key tool of water finding and plugging technology. The success ratio of water finding and plugging technology directly depends on capabihty of water finding switch. A new - style switch has been applied in Tuha oilfield with 100% success ratio on site. can accomplish two missions at one time, namely finding The combination of water finding switch and plugging string water and plugging water. Therefore water finding switch can simplify the process of operation and economize workover cost.
