Research on natural gas development corridor and planning based on coal-gas synergy
In response to the dilemma of overlapping coal and natural gas resources in the Xinjie Taigemiao mining area,which makes coordinated development difficult,a theoretical analysis of the technical system and principles of coal-gas synergy development was con-ducted.The study showed:constructing a natural gas development corridor system based on the timing of coal development and the de-mand for natural gas gathering and transportation was the optimal solution for efficient development of resource overlapping areas;the max-imum centering distances between corridors based on directional wells and horizontal wells in the mining area were 3 250 m and 4 350 m respectively;considering both the continuity of coal production and the regional natural gas recovery time,a 15-year service of the corri-dors in the mining area can basically meet the economic life of natural gas development.The ideas and main technical principles for coal-gas synergy development were provided.Spatial and temporal avoidance through the corridor model can ensure the safe,efficient,and orderly development of coal-gas resources.The research results can provide theoretical and case references for the coordinated de-velopment of resources in the coal-gas mining rights overlapping area of the Ordos Basin.
