摘要： An orienter, particularly on coiled tubing or small diameter drill pipe, includes a motor, turbine, or other device for selectively converting the rotational kinetic energy produced from fluid flow through the device to mechanical power, and applying the mechanical power to a downhole tool through a gear train for orienting the downhole tool. The orienter is utilized during directional drilling and other operations such as well intervention, fishing, and multilateral re-entry operations. The downhole tool preferably includes a steerable mud motor. In one embodiment, the direction of the borehole is controlled by azimuthal rotation of the orienter of the present invention in response to downlink commands from the surface by changing fluid flow rate through the orienter in a predefined series of steps.

摘要： Specific apparatus and associated methods are described for use in establishing the positions of locating field detectors and for path mapping within a region for the purpose of tracking and/or guiding the movement of an underground boring tool. In one aspect, an improvement is provided forming part of an arrangement for tracking the position and/or guiding the boring tool using an electromagnetic locating signal which is transmitted from the boring tool as the boring tool moves through the ground. At least two detectors are located at fixed positions within the region, each being operable in a transmit mode and in a receive mode such that each one of the detectors in the transmit mode is able to transmit a relative locating signal to the other detector for use in determining the relative position of one detector in relation to the other and such that both detectors receive the electromagnetic locating signal in the receive mode for use in determining the position of the boring tool within the region. Provisions are also described for extending drilling range by using additional detectors by moving a limited number of detectors. In another aspect, a system is provided including at least two above ground detectors for sensing the locating signal. The detectors are located at initial positions in the region. Electromagnetic data is generated by the detectors with the boring tool at multiple positions to generate electromagnetic data which is used to identify the positions of the detectors. A selected flux pathline steering technique is introduced.

摘要： A mounting arrangement for a pendulum in a downhole drift indicator comprises a plunger and a pendulum defining respective normally spaced apart first and second surfaces, and a pivot connection between the plunger and pendulum including a connecting pivot member. On the pivot connection being subject to a predetermined load the first and second surfaces engage to limit the load experienced by the pivot member. Also disclosed is a drift Indicator biassing arrangement, the arrangement including a housing partially defining a volume for containing a fluid reservoir, a signalling plunger and floating piston defining respective wall portions of the volume and being moveable relative to the housing. A spring acts on the piston to compress the fluid in the volume and move the signalling plunger relative to the housing.
