摘要： The present invention generally relates to an apparatus and method of jarring with an overpull generator (100). In one aspect, a method of dislodging an object (20) stuck in a wellbore (10) is provided. The method includes the step of running an assembly into the wellbore on a conveyance member (50) and attaching the assembly to the object, wherein the assembly comprises an overpull generator and a delay force release device (150). The method also includes the step of generating an overpull force in the wellbore by selectively activating the overpull generator. Additionally, the method includes the step of applying an impact force to the object by activating the delay force release device and releasing the generated overpull force, thereby dislodging the object stuck in the wellbore. In a further aspect, an assembly for dislodging an object stuck in a wellbore is provided. In yet a further aspect, an overpull generator for use in generating an overpull force in a wellbore is provided.

摘要： Embodiments of the present invention generally relate to extendable cutting tools for use in a wellbore. In one embodiment, a tool for use in a wellbore includes a tubular body having a bore therethrough, an opening through a wall thereof, and a connector at each longitudinal end thereof; and an arm. The arm is pivotally connected to a first piston and rotationally coupled to the body, is disposed in the opening in a retracted position, and is movable to an extended position where an outer surface of the arm extends outward past an outer surface of the body. The tool further includes the first piston. The first piston is disposed in the body bore, has a bore therethrough, and is operable to move the arm from the retracted position to the extended position in response to fluid pressure in the piston bore exceeding fluid pressure in the opening. The tool further includes a lock operable to retain the first piston in the retracted position; and a second piston operably coupled to the lock.

摘要： The present invention describes a drill pipe in which various sections of the pipe are strengthened, or their shape is altered, in order to improve the wear and buckle resistance of the drill pipe; or in which various damaged sections of the pipe are repaired in order to maintain or improve the wear and buckle resistance of the drill pipe. In either case, the sections are strengthened using various hardening methods such as heat treatment processes and/or expansion techniques. A sleeve can also be applied to the strengthened portions. Surface enhancers, such as hardbanding, can be applied to the strengthened portions or the sleeve in order to provide abrasion resistance or to reduce friction.
