摘要： The short hop communication link includes a sensor module (125) positioned downhole from a motor (100) in a well. The module (125) includes sensors that monitor operational, directional and environmental parameters downhole and provide an electrical data signal indicative thereof. Sensors may also be positioned in the drill bit (50) for obtaining parameters related to the bit, and communicating data signals reflecting the sensed parameters to the sensor module (125). The sensor module (125) includes a transceiver, with an annular antenna (25), for transmitting electromagnetic sensor data signals to a point above the motor (100). A control module (40), which also includes a transceiver with an annular antenna (27), is located above the motor (100), and receives the electromagnetic signals from the sensor module (125) reflecting the sensed parameters. In addition, the control module (40) is capable of transmitting command signals to the sensor module (125) requesting data regarding desired parameters. The command module (40) connects to a host module (10) which orchestrates all measurement-while-drilling components downhole. The host module (10) connects to a mud pulser (35) for transmitting desired data to the surface for real-time processing. The sensor module (125) is strategically placed within a removable, interchangeable sub (200) below the motor (100), or alternatively, within an extended driveshaft (400) of the motor (100), while the sensor antenna (25) is located on an exterior shoulder of the sub (200) or driveshaft (400). The sensor module (125) and an associated battery pack (55) reside within a pressure container (99) which forms part of a current return path from the sensor antenna (25) to the circuitry within the sensor module (125).

摘要： The present invention relates to safety joints which permit separation of a downhole assembly at the location of the joint. The invention provides a safety joint characterised by the provision of auxiliary interconnecting means on a body (2) for interconnecting said body (2) to an auxiliary shaft after removal of a main shaft (3) from said body (2). Axial loading between the auxiliary shaft and said body (2) may be thereby transferred. Furthermore, torque may also be transferred between the auxiliary shaft and said body (2) in a direction opposite to that in which torque may be transferred from the main shaft (3) to said body (2). Thus, the present invention allows a length of downhole assembly located above said body (2) to be removed from a wellbore by rotation of said length of assembly in a first direction and then allows rotation of said body (2) in the same first direction by means of the auxiliary shaft in an attempt to remove a length of assembly stuck in the wellbore downhole of said body (2).

摘要： A rolling cone bit (10) includes at least one roller cone cutter (14, 15, 16) having a gage row of cutter elements (60) and a first inner row of near but off-gage cutter elements (70) that are positioned so as to divide the sidewall and the buttom hole cutting duty so as to enhance bit durability, maintain borehole diameter and improve ROP. The off-gage distance (D) of the first inner row of cutting elements is defined for various bit sizes to optimize the division of cutting duty. The distance that the first inner row of cutter elements (70) are off-gage may be constant for all the cones on the bit (10) or may be varied among the various cones to balance the durability and wear characteristics on all the cones of the bit.

摘要： The present invention relates to hydraulically operated sliding side-door sleeves for use in wellbores. The invention provides an assembly (2) comprising an outer member (4) defining a bore and an inner member (38) defining a bore. The inner member (38) is slidably located within the bore of the member (4) so as to be movable between an open position and a closed position. The assembly (2) further comprises controlling means for selectively placing the inner member (38) in the open or closed positions. The controlling means comprises a spring (46) for biasing the inner member (38) in one axial direction relative to the outer member (4), means for shifting the inner member (38) relative to the outer member (4) against the bias of the spring (46); and selectively releasable latching means for latching the inner member (38) in the shifted position. The present invention has the advantage of being readily used in both vertical and "high angle" or horizontal wellbores.

摘要： A polycrystalline diamond layer (27) is bonded to a cemented metal carbide substrate (21) by this process. A layer of dense high shear compaction material (27) including diamond or cubic boron nitride particles is placed adjacent to a metal carbide substrate (21). The particles of diamond have become rounded instead of angular due to high shear compaction in a multiple roller process. The volatiles in the high shear compaction material are removed and binder decomposed at high temperature, for example, 950 DEG C, leaving residual amorphous carbon or graphite in a layer of ultra hard material particles on the carbide substrate. The substrate and layer assembly is then subjected to a high pressure, high temperature process, thereby sintering the ultra hard particles to each other to form a polycrystalline ultra hard layer (27) bonded to the metal carbide substrate (21). The layer of high shear compaction material is also characterized by a particle size distribution including larger and smaller particles that are distributed uniformly throughout the layer.
