【摘要】 修井作业中,起下油管、上卸扣采用传统作业方式过程复杂,劳动强度高,作业环境恶劣,针对这种情况,提出了一种新的修井作业井口机械化系统设计方案。系统仍利用现有的通井机,用一个自动吊卡和一个动力卡瓦代替原来的2组吊卡,井架上安装自动吊卡运行导轨,用坐式自动化闭口液压动力大钳代替原悬吊式开口液压钳,并配备管柱自动拉排滑车机构拉送排放油管。该方案可实现井口无人化操作,通过控制台操作设备运行,改善了修井作业环境,安全环保,为修井作业自动化做出了初步探索。
【Abstract】 In workover operation,running and pulling tubing and threading and unthreading in conventional way make the process complex,labor intensity high and operating environment hostile. For solving the problem,the new design scheme for workover wellhead mechanical system is put forward. The existing drifting device is still used in the new system,but an automatic hanger and a power slip are used to replace the previous two sets of hangers. The automatic hanger guide rail is installed on the derrick. The seating-type automatic closed hydraulic power tong is used to replace the previous hanging open hydraulic tong,and the automatic string laying tackle mechanism is prepared to lay the tubing. The unmanned operation at the wellhead can be realized in this scheme. The devices are controlled via the control table,which improves the workover environment,keeps safe and environment-friendly,and provides the preliminary exploring for the automation of workover operation.
