摘要
河南省深部煤系气资源潜力巨大,但煤系气储层普遍具有低压、低渗、低饱和特性,同时发育煤层普遍具有构造煤特征,深部煤系气勘查开发存在较大不确定性风险.为了降低深部煤系气勘探开发风险,提高资源综合开发利用效益,结合河南省深部煤系气与地热资源赋存特征,对河南省深部煤系气与地热资源协同开采问题进行了一些思考,分析了目前深部煤系气钻井工艺、井身结构以及排采工艺流程,同时结合地热资源开发利用新技术,针对气、热协同共采过程中存在的冲突点提出了技术及工艺流程改进思路,为实现河南省深部煤系气与地热资源协同共采目标进行了有益的探索.
Abstract
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.
