AI Technical Summary

Technical Problem

Existing technologies cannot monitor the settling location and velocity of pulverized coal in the coal seam fracture system in real time, resulting in reduced gas production in coalbed methane wells, and the experimental simulation results differ from the actual situation.

Method used

Design a real-time testing device for the location and velocity of pulverized coal transport and settling under various flow conditions, including a mixing and injection system, a fracture control system, a pulverized coal transport monitoring system, and a recovery system. Utilize a CCD industrial camera to monitor the pulverized coal settling location and velocity in real time, simulate different fracture systems through flexible, transparent, and elastic pipelines, and analyze the data using a high-performance computer.

Benefits of technology

It enables real-time monitoring of pulverized coal under different flow velocities, inclination angles, and flow regimes, providing theoretical guidance, a basis for formulating reasonable drainage systems, reducing the risk of pulverized coal blockage, and increasing the gas production of coalbed methane wells.
