摘　　要：单级三段液力投捞配水器是注水工具中的一种新的技术工具，该工具采用机械间隙密封手段，利用单级水心子对３个注水层段进行有效分隔，利用注水井液力进行反循环，实现该配水器水心子的液力投捞，降低测试成本和工人的劳动强度，省去不必要的大型动力测试设备。该配水器还可以灵活变通，实现四层分注井的液力投捞，具有很好的经济效益。Single - stage hydraulic drop - dipper type injection flow regulator for three intervals is a new tool. The tool adopts mechanical seal means to separate effectively three intervals by using single - stage water core. Hydraulic fishing of the tool is realized by hydraulic reverse circulation in water injection well. The tool reduces testing cost and worker's labour intensity. The water orator can flexibly apply to water injection well for four intervals.It has good economic benefit.
