摘要： An accelerometer has a housing defining a chamber, and a magnetizable fluid 11 within the chamber. A permanent magnet is magnetically suspended within the chamber by the magnetizable fluid with its poles oriented along a displacement axis so as to be displaceable from a null position along the displacement axis by an applied force. At least parts of the outer surface of the permanent magnet in the vicinity of its poles are provided with non-magnetizable end members. A sensing arrangement is provided for detecting displacement of the permanent magnet along the displacement axis and for supplying an electrical signal indicative of the applied force. Such an accelerometer is relatively immune to calibration drift and has high measurement accuracy.

摘要： A down-hole signal generator for a mud-pulse telemetry system comprises a flow constrictor defining a throttle orifice for the mud passing along a drill string, a throttling member displaceable with respect to the throttle orifice to modulate the mud pressure for the purpose of transmitting measurement data up the drill string, and a turbogenerator. The turbogenerator incorporates an annular impeller surrounding a casing and arranged to be driven by the mud passing along the drill string, and a rotatable magnet assembly disposed in a mud-free environment within the casing. The impeller includes an electrically conductive drive ring and the rotatable magnet assembly includes rare earth magnets, so that, when the impeller is rotated by the mud flow, eddy currents are induced in the drive ring by the magnetic field associated with the magnets and the magnet assembly is caused to rotate with the impeller by virtue of the interaction between the magnetic field associated with the magnets and the magnetic field associated with the induced currents. In this manner torque may be imparted to an electrical generator within the casing without a rotating seal having to be provided between the impeller and the generator.

摘要： An instrument for monitoring the direction of a borehole comprises an elongate casing having its longitudinal axis coincident, in use, with the axis of the borehole, an outer gimbal pivotally mounted within the casing with its pivot axis coincident with the longitudinal axis of the casing, a gyroscope unit mounted in the outer gimbal, a torque motor and a gravity sensor unit. At the beginning of a run the instrument is positioned at the mouth of the borehole. The rate of rotation about an axis transverse to the outer gimbal axis is then sensed by the gyroscope unit, and the outer gimbal is slewed by the torque motor in dependence on the sensed rate so as to align the transverse axis along an East/West direction. The instrument is then moved along the borehole and the rate of rotation about the outer gimbal axis is continually sensed by the gyroscope unit, the outer gimbal being torqued by the motor in dependence on the sensed rate to stabilize the outer gimbal about its axis. Simultaneously the components of gravity are sensed by the gravity sensor unit. The resulting measurements are used to determine the inclination and azimuth at a plurality of points along the length of the borehole.

摘要： A down-hole signal generator for a mud-pulse telemetry system comprises a flow constrictor defining a throttle orifice for the mud passing along a drill string, a throttling member displaceable with respect to a casing to modulate the mud pressure for the purpose of transmitting measurement data up the drill string, and a turbogenerator incorporating an electrical generator within the casing. The flow constrictor and casing form an integrated unit which is installed within a drill collar and is retrievable by drawing it up the inside of the drill string. The throttling member is displaced by a pump according to the torque required to drive the rotor of the generator which is dependent on the electrical load of the generator. The pump incorporates a rotary valve member which supplies the output of the pump to one or other side of a double-acting ram according as to whether the valve member is rotating with a first phase of rotation or a second phase of rotation. The phase of rotation is determined by a torque-sensitive actuator coupled to the valve member by a shaft and incorporating an escapement plate tiltable about an axis transverse to the shaft by a torque drive arm for driving the rotor.

摘要： When surveying a borehole using an instrument responsive to the earth's magnetic field, the assumption is made that the error vector which comprises the difference between the true earth's magnetic field and the measured magnetic field in the borehole is in the direction of the borehole axis. The magnitude of this error vector is determined and used to correct the magnetically measured azimuth.

摘要： A borehole drilling and survey assembly includes a drill string of magnetic material, a non-magnetic drill collar, and a non-magnetic rotary drilling system including a drill bit. A near-bit survey instrument is located in the rotary drilling system at a fixed distance from the junction of the drill string and the drill collar. A second survey instrument is located in the drill collar at a fixed distance from said junction. The survey instruments measure the local values of the component of the earth's magnetic along the borehole axis, and these values are processed to remove the magnetic effects of the drillstring. The survey instruments optionally also measure gravity vector components to enable borehole heading to be derived.

摘要： A system for maintaining a downhole instrumentation package in a roll stabilised orientation with respect to a drill string comprises an instrument carrier which is mounted within a drill collar for rotation about the longitudinal axis of the collar. An impeller is mounted on the instrument carrier so as to rotate the carrier relatively to the drill collar as a result of the flow of drilling fluid along the drill collar during drilling. The torque transmitted to the instrument carrier is controlled, in response to signals from sensors in the carrier which respond to the rotational orientation of the carrier, and input signals indicating the required roll angle of the carrier, so as to rotate the carrier in the opposite direction to the drill collar and at the same speed, so as to maintain the carrier non-rotating in space and hence roll stabilised. The torque may be controlled by controlling a variable coupling between the impeller and the carrier and/or by controlling a brake between the carrier and the drill collar.

摘要： An accelerometer has a moving magnet within a housing. The magnet is mounted within a support member connected to the center of a diaphragm so as to permit movement of the magnet along a measurement axis extending in the axial direction of the support member by deformation of the diaphragm and so as to permit movement of the magnet along two mutually orthogonal measurement axes parallel to the diaphragm by flexing of the diaphragm to allow for pivoting of the support member. Furthermore displacement of the magnet with respect to the three mutually transverse measurement axes in response to an applied force is sensed by a pickoff capacitor, and a respective output signal proportional to the component of the applied force along each of the measurement axes is supplied by associated sensing circuitry. Simultaneously the magnet is restored to its null position by associated force coil pairs. The use of a single magnet for measurement along the three axes renders the accelerometer of high accuracy and decreases the size of the measurement assembly.

摘要： A down-hole signal transmitter includes an annular impeller mounted on a cylindrical casing and arranged to be driven by the mud flow passing along a drill string. Each of the impeller and the casing incorporates two sets of magnets with their poles arranged axially relative to one another such that axial movement of the impeller in one direction will tend to be resisted by a force of magnetic repulsion acting between the first set of casing magnets and the second set of impeller magnets and axial movement of the impeller in the opposite direction will tend to be resisted by a force of magnetic repulsion acting between the second set of casing magnets and the first set of impeller magnets. In this way the axial thrust due to the fluid flow is largely taken up. Furthermore the magnetic coupling between the magnet sets in such as to enable driving torque to be transmitted by the impeller to a rotary drive member on which the casing magnets are mounted.
