Abstract
1,126,019. Well logging. DRESSER INDUSTRIES, Inc. Aug.23, 1967 [Sept. 19, 1966], No. 38800/67. Heading G1N. The depth of a logging sonde is estimated by an electromagnetic sensor detecting its passage past joints in the casing pipe. The resulting pulses momentarily activate an oscillator, or gate a balanced modulator driven by a free-running oscillator, to transmit signals to the surface. As described the sensor is incorporated in the sonde casing, the sensing-coils (30), (31), Fig.2 (not shown), being connected to a two stage transistor amplifier Fig. 3 (not shown), to pulse energize a transistor oscillator (48) Fig. 2. A gauged switch is provided for calibration and range changing.
