Title: Downhole tool

Abstract

A double shouldered downhole tool connection comprises box and pin connections having mating threads intermediate mating primary and secondary shoulders. The connection further comprises a secondary shoulder component retained in the box connection intermediate a floating component and the primary shoulders. The secondary shoulder component and the pin connection cooperate to transfer a portion of makeup load to the box connection. The downhole tool may be selected from the group consisting of drill pipe, drill collars, production pipe, and reamers. The floating component may be selected from the group consisting of electronics modules, generators, gyroscopes, power sources, and stators. The secondary shoulder component may comprises an interface to the box connection selected from the group consisting of radial grooves, axial grooves, tapered grooves, radial protrusions, axial protrusions, tapered protrusions, shoulders, and threads.

  • A downhole tool for insertion in a drill stem includes elongated cylindrical half sleeve tool sections adapted to be non-rotatably supported on an elongated cylindrical body. The tool sections are mountable on and removable from the body without disconnecting either end of the tool from a drill stem. The half sleeve tool sections are provided with tapered axially extending flanges on their opposite ends which fit in corresponding tapered recesses formed on the tool body and the tool sections are retained on the body by a locknut threadedly engaged with the body and engageable with an axially movable retaining collar.more » The tool sections may be drivably engaged with axial keys formed on the body or the tool sections may be formed with flat surfaces on the sleeve inner sides cooperable with complementary flat surfaces formed on a reduced diameter portion of the body around which the tool sections are mounted.« less
  • A tool is provided for making vertical slots in the sidewalls of either cased or uncased wells. The tool consists of a housing which may be lowered into a well by wire line. This housing has an elongated, longitudinally extending opening in the wall and a motor within the housing. The motor is supplied with power to an electrical cable. A cutter is mounted for movement in a vertical plane and is mechanically coupled to a motor so as to be driven by it. The cutter may be moved longitudinally of the housing. It may also be moved transversely ofmore » the housing to cause it to project through the opening and into cutting relation with the side wall of the well at the first part of the longitudinal movement. Then it may be moved longitudinally of the housing while projecting through the opening, thus cutting a vertical slot in the sidewall. Finally, it may be retracted into the housing at the latter portion of such longitudinal movement.« less
  • An apparatus is disclosed to indicate at the surface when a tool lowered into a well bore on an electric cable is properly positioned in a downhole housing. The tool has a key slot and a muleshoe is carried by the tool to engage a key located on the housing and to guide the key into the key slot to properly position the tool. A sensing coil is carried by the tool and positioned for its magnetic field to pass through the key slot. Circuit means monitor the magnetic field and indicate at the surface when the key has beenmore » properly positioned in the slot.« less
  • This patent describes an apparatus for carrying an object into a well. It comprises: a housing having a chamber for receiving an object to be carried into a well; and shock absorbing means, connected to the housing, for absorbing shock in response to the apparatus being dropped into the well and the shock absorbing means engaging in the well a stop which prevents further downward movement of the dropped apparatus in the well, the shock absorbing means including: an elongated member; and a sleeve connected at one end too the housing and receiving at another end the elongated member somore » that the elongated member retracts and extends relative to the sleeve, the sleeve having effective outlet areas which are progressively reduced as the member retracts into the sleeve in response to the member engaging the stop in the well.« less
  • A self powered downhole tool anchor device is disclosed. It is preattached to a downhole tool (T) and unitarily supported by a drill string (DS) for a single trip into a well bore, actuated by forceful engagement with the bottom or plug (P) in the well bore and attachment to a well bore casing (C). The anchor device comprises an inner mandrel and lower cone containing a piston and fluid (F) for axially displacing an outer mandrel and piston connected thereto by shear screws. An upper cone on the outer mandrel is connected by shear pins to a slip housingmore » containing radially expandable slips keyed to the lower cone. A self contained power supply (PS) of combustible material (M) is ignited by a firing pin striking a primer igniter (I) and generates gas pressure applied to the piston 30 and fluid (F) to shear pin and axially displace the outer mandrel and piston upper cone slip housing slips and ratchet ring relative to inner mandrel and cone. Screws are then sheared off releasing upper cone from slip housing and allowing relative displacement therebetween to radially expand slips into gripping engagement with the well bore casing (C). A mechanical firing mechanism includes a preloaded compressed spring actuated hammer retained against a spring housing and in a cocked firing position by a shear pin extending from an outer housing. A trigger engaged by the spring housing has a foot which engages the bottom of or plug (P) in the well bore. Lowering of a predetermined amount of weight of the assembled unit causes pin to shear and release the hammer which strikes and propels the firing pin into the igniter capsule I.« less
