摘要
为了解决修井作业过程中由于稠油井杆断脱所造成的作业施工中带来的不方便和不利因素,研制了油管内空心杆捞筒。该捞筒能够很好的代替原有的打捞工具,解决了原有打捞器牙片易碎、易脱且成功率低、成本高、不易购买等问题,为企业节省了成本。
In order to solve the difficulty caused by heavy oil well rod dropout during workover process, the tubing hollow rod overshot was developed. The overshot can well replace the original fishing tools to solve the original fisher＇s deficiency, which can save cost for enterprises.
