摘要： A settable down hole includes a set of metal slips which include intersecting zones of weakness in the metal which fracture into a large set of pieces during setting of the tool so the pieces can be circulated out of a well without further reduction in size. One zone of weakness is a closed bore passage extending axially through one or more of the slip segments. An expander cone of increased hardness allows an increased angle on the expander cone and slips.

摘要： A rotatable downhole cutting tool configured for enhanced drive consistency in low power circumstances. The tool is equipped with a hydraulic axial drive actuator suitable for use in wireline deployment. The actuator itself includes a reciprocating piston with a ball screw that threadably interfaces a ball nut for dampening the axial drive imparted by the piston. As such, even though hydraulically driven at generally well under about 10 horsepower, bounce in the axial drive is substantially eliminated.

摘要： A multi-stage flow sub usable in wellbore operations provides for flow of fluid from a tool string to a wellbore annulus, and may provide for one or more of controlling wellbore pressure during a tool operation, or preventing stripping of wet string. The multi-stage flow sub may include a housing having an axial bore and at least one flow passage. A sleeve within the housing may have an axial bore, a shoulder acting as a ball seat, and first and second axially offset flow passages. A first burst disc may be in fluid communication with the first flow passage, and a second burst disc may be in fluid communication with the second flow passage, the second burst disc having a higher burst pressure than the first burst disc.

摘要： Cutter blades extend and stay extended as long as pressure on a piston is continued. The blades either open fully in open hole or cut through the wall of a tubular and then mill in an uphole direction to take out a piece of the tubular. The piston that held out the blades when pressure was applied is acted on by a return bias when the pressure is removed so that the blades can retract and the tool removed through the cut tubular. As a backup a plug can be dropped to obstruct a through passage in the piston so that pressure from the surface can be used to force the piston back to retract the blades. Continued drilling operations or the cut and milled portion can be then blocked off such as with cement for a plug and abandonment of the well.
摘要翻译： 只要继续活塞上的压力，切割刀片就会延伸并保持延伸。 叶片可以在开放的孔中完全打开或切割穿过管状壁，然后在井上方向上研磨以取出管状件。 当施加压力时将叶片压出的活塞在压力被移除时通过返回偏压来作用，使得叶片可以缩回并且工具通过切割的管状物移除。 作为备份，可以将塞子掉落以阻塞活塞中的通过通道，使得可以使用来自表面的压力来迫使活塞向后缩回叶片。 接下来的钻孔操作或切割和铣削的部分可以被堵塞，例如用水泥塞塞和废弃井。

摘要： A method (50) and an assembly (10) for milling an obstruction disposed within a wellbore (W) includes a milling module (12) having a motor (22) rotating a milling bit (14), a first electronics cartridge (26) for controlling the motor based upon a motor torque value, a tractor module (16, 18) for engaging with the wellbore and providing a push force against the wellbore to urge the milling assembly in a direction of the milling bit, and a second electronics cartridge (28) for controlling a push force value of tractor module. The method involves rotating the milling bit (54) and engaging the tractor module with the wellbore (56), and adjusting, iteratively, the operation (58) based on a calculated torque value and a calculated push force value to maintain the calculated values at around a target torque value and below a push force limit value (66, 70).
