The company cooperates with Sinopec Engineering Institute to install self-developed high-frequency pressure data and "compression expansion companion wave" acquisition equipment at the wellhead, which is sent to the cloud in real time. Through cloud processing, the relevant data is sent to the company's computing center for data decryption and distribution. The distributed data enters the supercomputing center for fluctuation analysis, and an interpretation report is automatically generated based on the calculation results and sent to the fracturing site.

Using specially designed circuits for measurement, the "compression expansion companion wave" waveform is directly displayed through hardware filtering, denoising, and weak signal amplification techniques.

After high-frequency data collection, threshold and other parameters are set to display the pressure change curve and pulse change curve in the high-frequency pressure graph. The number of "compression expansion companion waves" is determined to achieve effective identification of the sliding sleeve, thus enabling reliable verification of the number of sliding sleeves that pass through.
