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.

这里公开的套管切割器对于切断井下管件是有用的。 包括本体，卡瓦，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卡瓦锚固在套管井筒内，在切割作业中提供锚固支撑。 切割是通过用相关马达旋转切割头来实现的，然后使切割刀片径向延伸远离切割头。 切割刀片由通过一系列齿轮可操作地连接到切割刀片的液压马达致动。
