摘　　要：现有的连续油管用弹簧式定位器的工作寿命低。分析导致其寿命低的主要原因,设计了一种液压式定位器。现场试验表明:研制的定位器可根据需要启动和关闭定位功能,改变了弹簧式定位器全井段被动定位的工作方式,从而延长了定位器的工作寿命。Aiming at the problem of low working life that currently coiled tubing spring locator has,the main reasons which caused low working life are analyzed,and a hydraulic locator is devel-oped. Field tests demonstrate that the hydraulic ｜ocator off according to requirement. Hydraulic locator changes cator thus extends working life. has full positioning ability to open localization process and shut spring lo
