针对目前堵水工艺存在找水不明确和堵水不准确、封隔器验封工艺复杂、丢手堵水管柱易下滑而造成工作寿命短等问题 ,研究出一种用于油田高含水期机械找堵水的液压调控找堵水一趟管柱。详细论述了该管柱及其关键配套工具 :自验封平衡式堵水封隔器、液压滑轨式调层开关器和强力支撑器等的结构和工作原理。这种液压调控找堵水一趟管柱用于现场堵水施工共 12井次 ,封隔器密封可靠 ,验封方便、直观 ;坐封压力 18～ 2 0MPa ,有效工作寿命达 1a ;封隔器防撞能力强 ,无中途坐封现象 ;管柱工艺成功率 10 0 % ,堵水效果明显 ,累计增产 2 374t。
Aiming at the problems such as the water seepage is not clear and the water plugging is not accurate, the packer sealing technics is complicated, the hand plugs and plugs are easy to slip, which leads to the short working life. Look for plugging the hydraulic control to find plugged water pipe string. The structure and working principle of the pipe string and its key supporting tools are discussed in detail: self-sealing closed balance water trap, hydraulic sliding rail type switch and strong support. This hydraulic control to find a block of water shut down for the construction of a total of 12 water shut-off construction wells, packers sealed reliable, easy inspection seal, set pressure 18 ~ 20MPa, effective working life of 1a; packer Strong anti-collision ability, no seated phenomenon; column process success rate of 10%, water blocking effect is obvious, a total increase of 2 374t.
