[0001] This disclosure relates to the field of high-pressure valve control in fracturing operations, and more particularly to a high-pressure valve control system for fracturing. Background Technology

[0002] Simultaneous fracturing of multiple wells using different techniques is a novel hydraulic fracturing technology. By simultaneously performing fracturing, pumping, ball-dropping, and CO2 injection in multiple wells, it significantly improves oil and gas recovery, increases construction efficiency, reduces construction costs, and enhances construction safety.
