液压式连续油管定位器研制

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 developed.Field tests demonstrate that the hydraulic locator has positioning ability to open and shutoff according to requirement.Hydraulic locator changes full hole localization process of spring locator thus extends working life.
