  • Patent number: 10465497
    Abstract: A system of near-bit measurement while drilling system includes motor system, measurement transmission system, wireless receiving system and non-magnetic short sub. The measurement transmission system is set inside the motor system, and the transmitting device from the measurement transmission system and the receiving device from the wireless receiving system are set inside the non-magnetic cavity. In the process of drilling via drill bit, the azimuth gamma and the well deviation parameters on the formation where the drill bit is located is able to be measured in real time more accurately and then will make real-time wireless transmission toward the wireless receiving system. Compared with conventional measurement while drilling work, the measurement location of the near-bit measurement while drilling system is nearer to the drill bit with non-hysteretic description of well trajectory and formation gamma measurement so as to enhance the drilling-encounter ratio significantly.

    Abstract: An electro-acoustic system for downhole telemetry employs a series of communications nodes spaced along a string of casing within a wellbore. The nodes allow wireless communication between transceivers residing within the communications nodes and a receiver at the surface. The transceivers provide node-to-node communication of data indicating elastic waves generated as a result of the formation of subsurface fractures. The data is processed which generates a map of fracture geometry. A method of evaluating fracture geometry in a subsurface formation uses a plurality of data transmission nodes situated along the casing string which send signals to a receiver at the surface. The signals are analyzed which generates a subsurface map.

    Abstract: A stacked-ring, slow-wave acoustic telemetry isolation system and method for use with tubular assemblies such as drillpipe or production tubing comprising an acoustic wave transmitter, the acoustic isolator behaving such that a “down” wave propagated toward the isolator is reflected back substantially in phase with an “up” wave propagated from the acoustic wave source away from the isolator. The acoustic isolator is similarly effective in reflecting “up” propagating waves originating from below the isolator, hence further protecting the acoustic wave source from possible deleterious interference. It causes substantially all of the emitted wave energy to travel in a chosen direction along the drill pipe, thus aiding the efficiency of acoustic telemetry said pipe.

  • Patent number: 8922387
    Abstract: A generally three-part EM gap sub comprising a first conductive cylinder incorporating a male tapered threaded section, a second conductive cylinder incorporating female tapered threaded section, both axially aligned and threaded into each other is described. One or both tapers incorporate slots whereby non-conductive inserts may be placed before assembly of the cylinders. The inserts are designed to cause the thread roots, crests and sides of the tapered sections of both cylinders to be spatially separated. The cylinders can be significantly torqued, one into the other, while maintaining an annular separation and therefore electrical separation as part of the assembly procedure. The co-joined coaxial cylinders can be placed into an injection moulding machine wherein a high performance thermoplastic is injected into the annular space, thereby forming both an insulative gap (the third part) and a strong joint between the cylinders in the newly created EM gap sub.

  • Publication number: 20140375467
    Abstract: An apparatus includes an acoustic sensor that receives a signal propagated by a well formation. The acoustic sensor includes a sensing component that receives the signal, a transmitter that transmits information based on the signal, and a receiver that receives the information. The transmitter and receiver are wirelessly coupled. The transmitter and receiver may be inductively coupled, capacitively coupled, or optically coupled, or the transmitter may transmit information using radio waves. The transmitter may be encapsulated in a polymer. The acoustic sensor may be part of a system including a downhole tool that detects subterranean conditions. The downhole tool may include a retaining member that retains the acoustic sensor within an outer layer of the downhole tool.

  • Patent number: 8880261
    Abstract: An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values ?a2, ?b2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2.

  • Publication number: 20140266770
    Abstract: An inground housing supports a transmitter for receiving electrical power from a battery. The transmitter transmits at least one signal using at least two different transmit power levels for at least one of locating the transmitter and characterizing an orientation of the transmitter. Based on detecting the battery voltage, the transmitter selects one of the transmit power levels. Transmitter output power can be controlled based on one or both of signal gain and duty cycle.

  • Publication number: 20140232548
    Abstract: A method for estimating a steady state response of a drill string in a borehole includes calculating a first displacement of the drill string in a frequency domain for a first excitation force frequency and a number of multiples of this frequency using an equation of motion of the drill string. The equation of motion has a static force component, an excitation force component, and a non-linear force component with respect to at least one of a deflection and a derivative of the deflection of the drill string. The method further includes: transforming the first displacement from the frequency domain into a time domain; calculating a non-linear force in the time domain; calculating a frequency domain coefficient derived from the calculated non-linear force in the time domain; and calculating a second displacement of the drill string in the frequency domain using the equation of motion and the frequency domain coefficient.
