  • Patent number: 12153181
    Abstract: A noise reduction measurement method of acoustic while drilling data based on signal synchronization is provided. The method performs pre-sampling before effective excitation of a low-frequency pulser, then extracts center frequency and phase information of noise of the low-frequency pulser by fast Fourier transform, and adjusts the excitation and sampling time of the acoustic signal according to the center frequency and phase information of the noise of the low-frequency pulser. Accordingly, the coincidence of the acoustic signal excited by the acoustic instrument and the acoustic signal generated by operation excitation of the pulser can be actively avoided, and the signal-to-noise ratio of the received signal of the acoustic instrument can be effectively improved.

    Abstract: A noise reduction measurement method of acoustic while drilling data based on signal synchronization is provided. The method performs pre-downsampling before effective excitation of a low-frequency impulse pump, then extracts center frequency and phase information of noise of the low-frequency impulse pump by fast Fourier transform, and adjusts the excitation and sampling time of the acoustic signal according to the center frequency and phase information of the noise of the low-frequency impulse pump. Accordingly, the coincidence of the acoustic signal excited by the acoustic instrument and the acoustic signal generated by operation excitation of the pulser can be actively avoided, and the signal-to-noise ratio of the received signal of the acoustic instrument can be effectively improved.

  • Patent number: 11305790
    Abstract: A self-driving steel coil transport vehicle capable of active steering includes a load-bearing device, bogies mounted below the load-bearing device, and wheels mounted under the bogies. Two bogies are provided and arranged in a front-rear manner along the running direction of the transport vehicle. Four wheels are mounted under each bogie, and the load-bearing device is articulated with the two bogies, respectively. The transport vehicle is drivable in both a straight line and curves.

  • Publication number: 20210184644
    Abstract: A sonic logging broadband impedance matching transformer modular design method and a module are related to sonic logging. The method includes the steps: obtaining component values of a multimodal equivalent circuit of a piezoelectric transducer by fitting actual impedance data of the piezoelectric transducer through a nonlinear regression method; selecting a T-type network structure composed of a matching capacitor and a matching inductor as a piezoelectric transducer impedance matching network structure; and presetting a to-be-matched frequency band and a reflection coefficient, and taking the multimodal equivalent circuit of the transducer as an artificial circuit load to optimize parameters of the piezoelectric transducer impedance matching network structure and a boosting transformer together so as to obtain final optimized parameters of the piezoelectric transducer impedance matching network structure and the transformer.

  • Publication number: 20210080602
    Abstract: In a method for synchronizing acoustic asynchronous serial signals while drilling, communication and high-voltage signal isolation between a transmitting terminal and a receiving master control board are realized in an asynchronous serial communication way. The receiving master control board serving as a master control terminal configures parameters for the transmitting terminal in the asynchronous serial communication way and controls the excitation of a sound source. The transmitting terminal is a synchronous sound source excitation signal initiator; signal synchronization is realized under an asynchronous communication condition due to the coordination of the transmitting terminal and the receiving master control board; the transmitting terminal includes a plurality of transmitting boards, and asynchronous serial communication between each of the transmitting boards and the receiving master control board is realized through two data lines R+ and R.
