管内水力切割器
摘要：
本发明属于石油开采领域，具体地，涉及一种管内水力切割器。采用上述结构的切割器切割小直径油管，能直接下放到油管设定的位置进行切割；该切割器进行切割时，井口液压控制切割，操作简单，安全可靠，对作业现场条件要求低，不会引发其它意外伤害；使用该工具切割油管，断口光滑，不会对油管造成损坏，为油管的再利用提供了可靠的保障。采用上述结构的切割器切割小直径油管，能直接下放到油管设定的位置进行切割；该切割器进行切割时，井口液压控制切割，操作简单，安全可靠，对作业现场条件要求低，不会引发其它意外伤害；使用该工具切割油管，断口光滑，不会对油管造成损坏，为油管的再利用提供了可靠的保障。
摘要（英）：

The invention belongs to the field of oil exploitation, and particularly relates to a hydraulic cutter in a pipe. When the hydraulic cutter in the pipe cuts small-diameter oil pipe, the hydraulic cutter in the pipe can be directly lowered to a set position of the oil pipe to cut,. Besides, the cutting is controlled by hydraulic pressure at a wellhead, thus operation is simple, safe and reliable, requirement of operation site is low, and no other accidental injuries occur. Meanwhile, when the oil pipe is cut by the hydraulic cutter in the pipe, fracture surfaces are smooth, the oil pipe is not damaged, and the recycle of the oil pipe is provided with reliable guarantee.
