针对常规不压井工艺在聚合物驱油井作业时 ,存在作业成功率低、施工工序复杂以及对断杆作业井不能压井等问题 ,研制了高强度脱接堵塞器和泵塞活门等新型不压井工具。高强度脱接堵塞器具有脱接器和堵塞器的功能 ,常规作业不增加起下管柱次数 ;它可采用上提抽油杆柱的方式封隔油管通道 ,起到压井的作用 ,从而可避免杆式开关或活门压井中的扭簧失效问题。泵塞活门安装在泵筒与泵固定阀连接处 ,不影响其它配套技术的应用 ,可取代常规的泵上、泵下活门 (或开关 ) ;与油管锚定装置结合使用 ,可替代下丢手管柱加开关的工艺技术 ;在抽油杆断脱的情况下 ,能自动关闭油管通道 ,保证不压井打捞管柱作业
Aiming at the problems of conventional well-killing process in polymer flooding wells, such as low success rate of operation, complicated construction process and inability to kill wells in broken bar working wells, etc., new types of new types such as high- Well killing tools. High-strength disconnect plug has the function of the detacher and the plug, the conventional operation does not increase the number of times from the lower column; it can be used to lift the sucker rod column way to seal the tubing passage, play the role of killing, which Avoids torsional spring failure problems in lever switches or valve killings. Pump plug valve installed in the pump cylinder and the pump fixed valve connection Department, does not affect the application of other supporting technologies, can replace the pump, pump under the valve (or switch); In conjunction with the tubing anchoring device, Column plus switch technology; in the case of sucker off, it can automatically close the tubing channel to ensure that the non-well fishing salvage operations
