Abstract

1378871 Boring earth &c MOBIL. OIL CORP 23 March 1973 [30 June 1972] 14140/73 Heading E1F [Also in Division G3] In a logging-while-drilling tool 46 having a rotary valve 60 generating pulses in the drilling fluid indicative of the magnitude of a down-hole condition measured by the tool, means 75 bias the valve to an open position when the tool is not operative. The valve comprises a rotor 61 having slots 61a and a stator 62 having slots 62a. The tool is housed in a drill collar 26, through which the fluid flows downwardly to rotate a turbine 52 driving a generator 50 supplying electricity to a motor 55 driving the rotor through a gearbox 56. A device 53 connected to a strain gauge 54 subjected to the condition controls the supply to the motor and hence the motor and rotor speeds and the frequency of the pulses are dependant on the condition. The means 75 comprises poles 78 on a stationary magnet 76 and projection 79 on a magnetic member 77 fixed to the shaft 63 of the rotor, the means tending to hold the rotor with its slots aligned with those of the stator so that the valve is in the open position.
