Abstract

See full text

The disclosure relates to petroleum drilling, specifically a downhole signal receiving and transmitting device. The downhole signal receiving and transmitting device includes a receiving part, a control device, a mechanical assembly and a transmitting mechanism. The receiving part receives a signal transmitted by a lower end instrument, and the control device process the received signal, controls a motor to drive a rotating sleeve, and the mechanical assembly performs work. The mechanical assembly drives a mandrel to rotate a rotor continuously and regularly. When rotating, the flow area of the rotor and a stator changes to produce continuous pulses. The pressure waveform changes are monitored on the ground, and the measurement data are calculated by decoding. The device can obtain engineering parameters and geological parameters in the downhole drilling process in real time, which helps engineers to adjust the drilling trajectory and related parameters, and realize real-time measurement and control while drilling.
