摘要： The present invention relates to a method and apparatus for measuring current resulting from a magnetic field source (i.e., a transmitter) positioned on a drill collar. A plurality of current detectors are carried on the surface of the drill collar in an insulated relationship thereto. Each of the detectors is positioned to detect the value of current being received by the same from the formation. In this connection, the detectors are positioned at differing longitudinally displaced positions relative to the axis of the drill collar and the transmitting antenna(s), whereby each detects a different value of current. These currents will respectively flow through successively deeper layers of the formation. The longitudinal displacement is directly proportional to the depth of investigation, whereby the depth of investigation is many times the longitudinal distance between the current detector and the corresponding transmitting antenna. This set of measurements then produces an estimate of the resistivity profile of the formation adjacent the borehole.

摘要： A subsurface valve-actuator combination for well production tubing is described. The valve is urged to closed position but held open by a battery-operated latch of the actuator. A receiver-relay in the battery-actuator circuit maintains a switch closed to permit the latch to be energized as long as the receiver-relay receives an electromagnetic signal transmitted from the earth's surface. The latch is deenergized upon interruption of the signal and/or if the battery power is insufficient to energize the same.

摘要： For the directional drilling of boreholes, the orientation of accelerometer modules, magnetometer modules and gyroscopes or other directional sensing devices must be accurately known and maintained with respect to each other and to external mounting devices. This is accomplished by a self-aligning segmented cylindrical connection which accurately maintains modules in rotational alignment with each other for all three directions of rotation, even if the mating surfaces of the connection experience wear due to rough use in the drilling application or repeated calibration in a calibration fixture. Wedged surfaces on each of the male and female portions of the connection constitute the mating surfaces, and are the only surfaces at which the male and female portions contact one another. A depression between the mating surfaces defined by the female portion permits reproducible angular displacement of one portion with respect to the other even if one or both portions are worn. The connection has great ability to resist relative rotation of the two segments being connected under the application of a bending force because the connection, by its unique design, translates bending load into tensile load with respect to the screws which fasten the connection together.

Various embodiments conforming to the design are described. Moreover, the invention includes transition and reflector sections, as well as a directional coupler and resonator arrangement particularly adapted for borehole acoustic communication.An acoustic communication system is described especially designed for use in providing acoustic transmission of information in a borehole. The communication system comprises a surface transceiver and at least one downhole transceiver. The surface transceiver operates in conjunction with a host computer that sends commands to the downhole transceiver. Subsequently, the downhole transceiver transmits encoded data from subsurface, borehole sensors to the surface transceiver. The preferred embodiment uses Minimum Shift Keying (MSK) modulation for both transmitting commands to the downhole unit and for transmitting data to the surface transceiver. To facilitate operation of a coherent communication system in the inhospitable environment of a borehole, the acoustic channel is characterized to enable the system to choose the best possible frequency and bandwidth for communication transmission. Additionally, the system achieves synchronous operation by transmitting synchronization signals between the downhole transceiver and the surface transceiver prior to the units exchanging commands and data.

摘要： The method and apparatus relies on a modified induction approach and preferably is incorporated into a metal drill collar for MWD measurements. A primary changing magnetic field is formed in a formation by a transmitting antenna which is in a groove on the surface of a drilling collar. Such drill collar also carries a plurality of detecting antennas and/or current detectors which detect the value of current induced in the formation to provide a resistivity profile immediately adjacent the borehole. An embodiment uses a hybrid modified induction and electrical approach.

摘要： The location method uses relatively low frequency electromagnetic fields, e.g., 1-1000 Hz, for determining the relative position and/or orientation of a transmitting magnetic dipole antenna by using a vector field receiver. The transmitting antenna for subterranean location, is preferably a single axis, elongated solenoid with a ferromagnetic core. The receiving sensor may be a precise three-axis magnetic field detector of either a magnetometer or search coil type. Measurements are made for one or more positions of either the transmitter or receiver, or with one or more transmitters or receivers. The relative location of the transmitter and the receiver is calculated with respect to some known survey station by a method of successive approximations. The operating frequency is chosen to minimize field distortion from common steel structures, such as pipe, casing or railroad tracks, and to minimize field scattering such as from conducting inhomogeneities in the earth. Either the transmitter or receiver can be operated within metal structures such as casing. The method can be used for location of underground boreholes or pipelines; location of trapped miners; as a means of blind surveying such as in underground mines; or as a means of navigation such as in relatively shallow horizontal or vertical drilling and tunneling or in raise bore mining.
