摘要
【研究目的】煤炭是中国的主体能源,煤层气(煤矿瓦斯)是煤矿生产过程中的重要危险源,同时也是一种重要的清洁能源。煤层气主要成分是甲烷,甲烷的温室效应是等体积二氧化碳的80~120倍,大量排入空气中会对大气环境产生严重影响。本文通过分析中国煤与煤层气勘查开发模式和技术现状,论证了煤与煤层气协同勘查开发的必要性和可行性,进而提出中国新的煤与煤层气协同勘查的技术途径。【研究方法】本文通过梳理大量前人资料和研究成果,分析了中国的能源供需、煤炭与煤层气协同勘查开发技术现状和发展趋势,讨论煤与煤层气协同勘查开发技术方向和对策。【研究结果】科学论证了实施煤与煤层气协同勘查开发的必要性和可行性,揭示其技术瓶颈,提出了煤与煤层气协同勘查技术体系,构建了煤与煤层气协同开发新模式,提出了未来煤与煤层气协同勘查开发利用关键技术及发展建议。【结论】实施煤与煤层气协同勘查开发非常必要和十分迫切;中国煤层低渗透率、低储层压力、低含气饱和度和复杂的地质和开采技术条件,决定了以煤与煤层气协同勘查开发为主、地面抽采为辅的煤层气开发利用方式;应深化煤与煤层气耦合成矿成藏规律研究,建立煤与煤层气协同勘查开发利用关键技术与CCUS技术相结合的技术体系。
[Objective]Coal is the primary energy source in China,while coalbed methane serves as an important and hazardous source of coal mine production process and a vital clean energy alternative.Methane,the main component of coalbed methane,exhibits a greenhouse effect 80-120 times stronger than the same volume of carbon dioxide.Excessive methane emissions can significantly impact environmental quality.This paper analyzes the patterns and technologies of coordinated exploration of coal and coalbed methane in China to demonstrate the necessity and flexibility of such an approach.Furthermore,it proposes a new technical approach for cooperative exploration of coal and coalbed methane in China.[Methods]The paper also analyzes and discusses energy supply and demand,the current state,and development trends of theories and technologies for co-mining coal and coalbed methane in China.Additionally,it studies and evaluates the development and utilization of coal and coalbed methane.[Results]The necessity and feasibility of implementing coordinated exploration and development of coal and coalbed methane are scientifically validated,and the main bottlenecks in China's of coordinated exploration and development of coal and coalbed methane are revealed.Moreover,the paper provides a technique system for coordinated exploration and development of coal and coalbed methane and presents a new development mode,key technologies,and development proposals for this approach.[Conclusions]In conclusion,the implementation of coordinated exploration and development of coal and coalbed methane is highly necessary and urgent.The characteristics of coalbed methane reservoirs(low permeability,low reservoir pressure,and low gas saturation)and complex geological conditions determine that cooperative exploration and development of coal and coalbed methane,with surface pumping as supplement,is the dominant mode in China.Considering the goals of carbon peaking and carbon neutrality,it is crucial to deepen research on the reservoir formation law of coal an
