Description

Technical Field

[0001] This invention belongs to the field of logging technology, and in particular to a method and related device for simulating the transmission noise of logging-while-drilling mud pressure wave signals. Background Technology

[0002] Logging while drilling pressure wave transmission refers to the uploading of bottom hole signals through the regular changes in mud pressure waves. The surface signal acquisition and processing system identifies and processes the pressure wave signals to obtain the real-time measurement parameters and working status of downhole instruments.

[0003] The mud pressure wave signal is affected by a variety of factors, including the performance of the mud pump, mud characteristics, well depth, mud viscosity, gas content, and sensor background noise at the drilling site. The pressure wave signal acquired by the surface acquisition and processing system is subject to various interferences, such as mud pump noise, resulting in a low signal recognition success rate and poor adaptability to different operating areas.

[0074] Based on the original pressure wave signal, the code element information can be obtained by decoding the original pressure wave signal according to the encoding rules;

[0075] Step 6: If the symbol information of the pressure signal generated in Step 1 cannot be effectively obtained or the bit error rate (BER) is high, adjust the configuration parameters of the signal processing method selected in Step 4 to verify whether the results are improved.

[0076] Step 7: If the effect is still not obvious, reselect the signal processing method and configuration parameters of Step 4, and repeat Step 5 and Step 6 until the original pressure wave signal generated in Step 1 can be completely recovered and its transmitted symbol information can be obtained.

[0077] Step 8: Based on the above configuration information, complete the signal processing and decoding of this simulated mud pressure wave transmission process, and save and record the corresponding configuration parameters to obtain the configuration diagram. Example

[0081] Step 4: Click the Generate button to generate the mud pressure wave signal and display its time domain and frequency domain signal waveforms in real time;

[0082] Step 5: Based on the signal characteristics, select appropriate signal processing methods and configuration parameters to process the actual signal and verify whether the original symbol signal generated in Step 2 can be effectively recovered;

[0083] Step 6: After effectively recovering the signal characteristics, record and store the configuration parameters for the current simulation environment, and carry out on-site operations.
