Abstract
The research on the effective utilization of deep coalbed methane (with a burial depth of over 2500 m) within the Sinopec system is still blank, while the Daniudi gas field has conducted practical exploration for the fracturing development of coal seams in the Taiyuan Formation of the Carboniferous Permian. The coal seam of the Taiyuan Formation in the Daniudi Gas Field is buried at a depth of 2500–3000 m, and overall belongs to medium rank coal with a primary fractured structure; The concept of “controlling near and expanding far” large-scale volume fracturing technology proposed based on this has been successfully implemented and achieved breakthrough progress. Based on practical situations, analyze the fracturing construction curve, clarify relevant reservoir and engineering parameters, analyze the crack propagation effect, and complete a comprehensive evaluation of the applicability of typical measures and well processes; And combined with long-term production tracking, clarify the characteristics of deep coalbed methane backflow and production after well pressure, providing experience and basis for effective utilization of deep coalbed methane in the later stage.
