远程控制液压油管防顶防喷装置的研制

Remote Control Hydraulic Anti-jack and Anti-blowout Device for Tubing Tripping

在油田井下作业起下油管过程中,为了防止出现井涌、井喷和油管上顶事故,研制了远程控制液压油管防顶防喷装置。该装置采用液压快插式堵塞技术,既能快速堵塞油管,又能开关油管内通道,保证压井需要。整套装置远程液压控制,在油管上顶管内溢突发状况时实现全部机械自动化控制,不需人员在井口上操作,减轻了工人的劳动强度。现场模拟油管内液体外溢,仅需34 s就完成堵塞器从井口外侧的对中、插入油管直至堵塞密封整个过程。该装置的自动化控制和远程控制在油田安全生产、环境保护和减轻施工人员劳动强度方面做出了贡献。

To prevent the accidents of kick,blowout and tubing jack during tubing string tripping in workover operation,the remote control hydraulic anti-jack and anti-blowout device has been developed. The device,using hydraulic plug-in plugging technology,could both quickly plug tubing and switch channels within the tubing to ensure the well killing needs. The whole set of device,which is remotely hydraulic controlled,could achieve mechanical automatic control when the tubing jacksand the overflow occurs,and reduced labor intensity feature without personnel operation on the wellhead. During the simulation of the overflow in the tubing,alignment,plug-in and plugging the tubing was completed in 34 seconds. The automatic control and remote control of the device contribute to the safe production,environmental protection and labor intensity reduction.
