摘要：
The casing cutter disclosed herein is useful for severing downhole tubulars and. comprises a body, slips, a cutting head, cutting blades, and actuators for operating the cutting head and cutting blades. The casing cutter can be anchored within casing wellbore with the slips to provide anchoring support during the cutting operation. Cutting is accomplished by rotatingly actuating the cutting head with an associated motor, and then radially extending the cutting blades away from the cutting head. The cutting blades are actuated by a hydraulic motor operatively coupled to the cutting blades by a series of gears.
摘要（中）：
本文公开的套管切割器可用于切断井下管和。 包括主体，滑动件，切割头，切割刀片和用于操作切割头和切割刀片的致动器。 套管切割器可以通过滑盖锚固在套管井筒内，以在切割操作期间提供锚固支撑。 通过用相关的电动机旋转地致动切割头，然后将切割刀片径向延伸远离切割头来实现切割。 切割刀片由通过一系列齿轮可操作地联接到切割刀片的液压马达致动。
