Exploration of Collaborative Extraction Techniques for Deep Coalbed Methane and Geothermal Resources in Henan Province
Henan province has immense potential in deep coalbed methane resources,but the coalbed methane reservoirs in this region generally exhibit characteristics of low pressure,low permeability,and low saturation.Additionally,the coal seams often display structural coal features,leading to significant uncertainties and risks in the exploration and development of deep coalbed methane resources.In order to mitigate these risks and enhance the overall utilization of resources,this study takes into account the coexistence of deep coalbed methane and geothermal resources in Henan Province.The paper explores the issues related to the collaborative development of deep coalbed methane and geothermal resources in Henan Province.It analyzes the current drilling techniques,wellbore structures,and extraction processes for deep coalbed methane,and incorporates new technologies for geothermal resource development.Addressing the potential conflicts in the collaborative extraction of gas and heat,the study proposes improvements in both technology and process flow.This research represents a valuable exploration towards achieving the goal of collaborative extraction of deep coalbed methane and geothermal resources in Henan Province.
