Numerical Simulation of Post-pressure Return Discharge of Shale Condensate Gas Wells and Determination Method of Return System

Shale condensate gas wells often require fracturing operations to improve production due to their compaction characteristics, and the post-compression return rate is generally low, and a large amount of fracturing fluid is trapped in the reservoir. Therefore, based on the actual production data, the characteristics of early production repatriation of shale gas wells are analyzed, and corresponding numerical models are established according to typical data, and the impact of different time well duration and production system on the return rate and production capacity of shale condensate gas wells is studied. The research results provide technical support for understanding the filtration loss mechanism of fracturing fluid and its storage method in the reservoir, and determining the optimal shut-off time and production system of shale condensate gas multi-stage fracturing horizontal wells.
