    摘要: A core breaker carrier for inserting and removing a core breaker from a drill bit. The carrier of the present invention eliminates the need for using wireline tools to install a core breaker within a drill bit. The core breaker carrier with core breaker attached can be inserted into the bore of the drill pipe at the well surface and pumped into the drill bit. Fluid pressure is used to anchor the carrier at a preselected location within the drill bit.

    摘要: In pump-down tools for use in well maintenance operations wherein fluids are injected into a well and wherein the tool includes a tubular member having locomotives positioned thereabout and a fluid passageway positioned therethrough and is connected to a fluid injection member positioned in fluid communication with the fluid passageway and the well; the well being equipped with a first tubing member and a second tubing member which are in fluid communication near their lower ends so that the tool is readily moved through the first tubing member by pumping fluid sequentially through the first tubing member, the junction between the first and second tubing member and the second tubing member and is moved in the opposite direction by reverse circulation, an improvement comprising positioning on the tubular member above the locomotives a sealing ring which is releasably maintained in position at a suitable angle from the axis of the tubular member.

    摘要: Apparatus for selective engagement with and disengagement from a well tool comprising: a tubular body having radial windows therein; a plurality of latches carried by the body for radial movement in the windows between retracted positions, engaging the well tool, and extended positions, disengaging the well tool; a cam member carried by the body and axially movable relative thereto to effect movement of the latches between the retracted and extended positions; and cooperable retainers carried by the body and the cam member permitting axial movement of the cam member in response to a predetermined axial force applied thereto. The latches may comprise pivot portions and longitudinally disposed finger portions extending therefrom so as to render the latches pivotable about the pivot portion, permitting radial movement of the tips of the finger portions between the retracted and extended positions. The cooperable retainers may comprise a plurality of collet fingers, on the cam member, having threaded tips engageable with corresponding threads carried on the body.

    摘要: A piston section of a TFL tool having an elastic substantially spherical sealing member is serially connected through a balland-socket flexible coupling to a scraper section having radially extending scraper blades. Clamping members located on opposite sides of the sealing member may be moved with respect to one another along the axis of the TFL tool to adjust the diameter of the sealing member by varying the axially compressive forces on the sealing member.

    摘要: A coupler for interconnecting spaced bodies in an articulated manner. One form of the coupler includes elongate locking fingers having external locking bosses along opposite ends and supported by a spring in parallel spaced relationship along opposite sides of a pair of elongated spacers. The spacers are movable longitudinally against the spring toward either end of the coupler to allow the locking fingers along the other end of the coupler to be squeezed together for coupling into or uncoupling from a locking recess of one of the spaced bodies. Upon release the spring returns the spacers to neutral aligned positions holding the locking finger in parallel noncompressible coupling relationship. Another form of the coupler includes rotatable spaced latch rings around the locking fingers at opposite ends of the spring. The latch rings have internal release recesses and locking flanges and are each rotatable between a first position at which the spacers are released to move longitudinally relative to the ring and locking fingers and a second position at which the spacers are held against longitudinal movement at neutral positions between the locking fingers holding the locking fingers against compression in coupling positions. Both forms of the coupler are useful for interconnecting a plurality of well tools to form an articulated train of tools for movement through a tubing string.

    摘要: Piston-less downhole tools and piston-less pressure compensation tools are presented. The piston-less downhole tool includes a first chamber comprising a first fluid, the first fluid being a fluid that thermally expands in response to an increase in a temperature of the first fluid. The piston-less downhole tool also includes a tubular having a first end that is fluidly sealed and a second end that is in fluid communication with the first fluid, wherein the tubular is configured to expand in response to thermal expansion of the first fluid. The piston-less downhole tool further includes a second chamber configured to store a second fluid. The tubular of the piston-less downhole tool is configured to contract in response to pressure applied by the second fluid.
