Filed:

Apr 6, 1998

Appl. No.:

09/056053

Inventors:

Kenneth J. Carstensen - Houston TX
Neal G. Skinner - Lewisville TX
Charles M. Pool - Bedford TX

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

G01V 300

US Classification:

3408543, 3408531, 367 83

Abstract:

An apparatus and method of communicating in a tubular system ( ) through a media ( ) disposed therein and actuating a controllable device ( ) are disclosed. The apparatus and method utilize a transmission apparatus ( ) at a transmission node that is in communication with the media ( ). The transmission apparatus ( ) generates pressure impulses that are propagated through the media ( ). The pressure impulses may be either positive or negative pressure impulses depending upon the selected transmission apparatus. The pressure impulses are detected by a reception apparatus ( ) at a reception node. The detection apparatus may detect the pressure impulses as variation in the media ( ) or as variation in the tubular system ( ) caused by the pressure impulses. Once the detection apparatus ( ) has detected the appropriate pressure impulse or pattern of pressure impulses, a signal may be generated to actuate the controllable device ( ).

Abstract:

A system and method in accordance with the invention communicator remotely with remotely controllable down hole tools in a well bore at a drilling installation. At the surface, high energy pressure impulses directed into the tubing or the annulus, or both, being at a level to propagate through an interface between very different impedances zones, such as an upper level gas zone and a lower level of mobile fluid media extending down into the desired downhole location. The pressure impulses, provided by directionally gating along the longitudinal confining path a pressure impulse initially having sharp leading and trailing edges, reach the downhole location as physical perturbations forming a discernible pattern that can be detected by one or more energy responsive transducers. With combinations of these signals, one of a number of separate control devices can be remotely actuated. The system avoids the need for physical or electrical connections and concurrently greatly reduces the likelihood of accidental operation.

International Classification:

Abstract:

Improved sucker rod joints for down hole petroleum pumping applications are provided within the form factor of standard API sucker rods, such that existing inventory in suitable condition is fully usable in more demanding applications. The pin ends are selected or processed such as to provide preselected axial distance between a flat pin end and at least one reference surface, such as a threaded region or reference shoulder or both. The coupler is dimensioned such that the pin ends are in abutment either with each other or with opposite sides of an intervening torque washer in the central region, when the connection is made to a selected level of thread engagement. Furthermore, the engagement is such as to put the pin ends in compression and the coextensive length of coupler in tension. This increases frictional restraints and locks the elements together to resist fatigue failure upon cycling and to insure together with an anaerobic adhesive sealant, against back threading. This arrangement enables standard quality sucker rods to be employed in a configuration which is mechanically secure and highly resistant to tensile, bending and torsional forces, thus assuring a greater strength at the joint than in the rod itself, and resisting the effects of material fatigue arising from long term and stressful cycling operations.

Abstract:

A device for coupling a driver system to a downhole string of sucker rods in a petroleum well employs a polish rod construction in which the polish rod is strengthened by an attached sleeve providing a transverse should in a predetermined plane. The sleeve is shrink fit in place and mechanically adhered to withstand the stresses and shocks encountered in long-term cyclic operation. The device provides specific benefits for an improved sucker rod connection which prestresses the sucker rod pin ends and the coupling in a fashion to resist the development of microcracks and fatigue failures.
