随着我国经济建设的突飞猛进,对能源的需求越来越大,因此煤层气的开采与开发具有重要的经济与社会效益。煤层气的高效开采的关键是运用科学合理的技术,同时对煤层气的排采过程进行动态的监测和评估能够更加准确的判断煤层气的开发及工作效率。本文主要运用超低频电磁探测原理及仪器分析煤层气排采过程中超低频谱的变化情况,并说明煤层气排采发生的动态变化。从而进一步揭示被动式超低频探测技术可以更加高效、简便、无损的探测出煤层气排采的状态。
With the rapid economic development in our country, the demand for energy is growing. Therefore, the exploitation and development of coalbed methane has important economic and social benefits. The key to efficient coalbed methane exploitation is to use scientific and reasonable technologies to dynamically monitor and evaluate the coalbed methane extraction process to more accurately determine the development and operational efficiency of coalbed methane. In this paper, the principle of ultra-low frequency electromagnetic detection and instrumentation analysis of ultra-low frequency spectrum of coal bed methane emissions in the process of change, and explain the dynamic changes of CBM production. This further reveals that the passive ultra-low frequency detection technology can detect the status of coalbed methane drainage more efficiently, simply and nondestructively.
