远程控制单吊卡起下管柱作业工艺
Tripping of pipe string using singular elevator with remote control
摘要
Abstract
During workover operation, tripping of toolstring may involve the heaviest workload and the longest working time. Conventional dual-elevator system extensively adopted in China for tripping toolstring are characterized by high labor intensity, poor working conditions and severe potential risks. To remove these problems, electric, hydraulic , pneumatic principles have been deployed to develop an innovative process for tripping toolstring by using singular elevator with remote control in accordance with existing hydraulic, electric and pneumatic conditions available on site. The innovative tripping system has following features: with hydraulic elevators attached to eyebolts on both side continuously, it is not necessary to operate elevator pins, eyebolts or replace elevators. In this way, problems related to operation of singular eyebolt in manual operation can be eliminated properly. Since manipulators can be used to position eyebolts on both sides to drive hydraulic elevators, and with flexible connections among eyebolts and elevators, the elevator may capture or release tubing at any angle vertically and horizontally. With lifting, lowering, connecting, transportation, centralizing and other operations of toolstring can be performed by operators through remote control, no operator is required on wellhead. In this way, labor intensity can be reduced effectively. In addition, with operational risks removed, safety of relevant operation can be guaranteed.关键词
