【摘要】：煤层气是以甲烷（CH4）为主要成分，以吸附状态赋存于沉积盆地的煤层中，与煤同体共生的能源矿产。煤层气是一种洁净能源，它的开发和利用，不仅可以减少煤矿开发的灾害，可以减少甲烷向大气中排放所造成的环境污染，而且可以接替和补充常规天然气的能源矿种，从而有着极大的经济价值、社会效益和环境效应。煤层气地面抽采在我国是一个新兴的行业，经过十几年的发展，部分开发条件好的地区已进入规模化、产业化的发展道路，但是由于各方面的原因和条件限制，以往的煤层气抽采项目中很少或是没有进行经济评价工作。为适应我国煤层气产业的快速发展的需要，提高项目决策的科学化水平，引导和促进煤层气产业健康、有序发展，充分发挥投资效益和社会效益，有必要对煤层气地面抽采项目进行经济评价研究。本文通过对煤层气地面抽采工程的开发方式、开发阶段、服务年限等进行研究；通过对煤层气地面抽采项目的特点、经济评价的作用和原则进行研究；通过对煤层有效厚度、含气量、渗透率、地解比、含气饱和度、吸附时间和水文地质条件等地质参数研究；对钻井工艺、完井工艺、增产工艺、排采工艺和生产系统工艺等工艺技术参数研究，对项目总投资、生产成本、煤层气价格等经济参数研究，并结合煤层气抽采项目的投资估算、资金筹措、生产收入、成本和费用、税收等经济指标，建立了煤矿区煤层气地面抽采项目经济评价的基本模型，该模型包括财务评价、国民经济评价和不确定性分析。通过对2个不同类型的煤层气抽采项目实例进行分析研究，结果表明：建立的煤矿区煤层气地面抽采经济评价模型是适用于煤层气地面抽采项目经济评价的，并且能取得良好的经济效益、社会效益和环境安全效益。论文通过对煤矿区煤层气地面抽采项目经济评价研究，，其经济评价指标和经济评价模型对以后类似的项目能起到经验借鉴作用。
[Abstract]:Coal-bed methane (CBM) is an energy mineral with methane (Ch _ 4) as the main component and the adsorption state occurring in the coal seam of sedimentary basin and coexisting with coal. Coal bed methane (CBM) is a kind of clean energy. Its development and utilization can not only reduce the disaster of coal mine development, reduce the environmental pollution caused by methane emission into the atmosphere, but also replace and supplement the energy and mineral resources of conventional natural gas. It has great economic value, social benefit and environmental effect. Surface extraction of coalbed methane (CBM) is a new industry in China. After more than ten years of development, some areas with good development conditions have entered the road of large-scale and industrialized development, but due to various reasons and conditions, In the past coalbed methane extraction projects had little or no economic evaluation work. In order to meet the needs of the rapid development of coal bed methane industry in China, improve the scientific level of project decision, guide and promote the healthy and orderly development of coal bed methane industry, give full play to the benefit of investment and social benefit. It is necessary to study the economic evaluation of coalbed methane extraction project. In this paper, the development mode, development stage, service life of CBM surface extraction project are studied, the characteristics of CBM extraction project, the function and principle of economic evaluation, the effective thickness of coal seam are studied. Research on geological parameters such as gas content, permeability, geo-solution ratio, gas saturation, adsorption time and hydrogeological conditions, drilling process, completion process, production increase process, production discharge process and production system process, etc. To study the economic parameters such as total investment, production cost, price of coalbed methane and so on, and combine economic indexes such as investment estimation, fund raising, production income, cost and expense, tax and so on. The basic model of economic evaluation of coalbed methane extraction project in coal mine area is established. The model includes financial evaluation, national economic evaluation and uncertainty analysis. Through the analysis and study of two different types of CBM extraction projects, the results show that the established economic evaluation model of CBM extraction on the ground is suitable for the economic evaluation of CBM extraction projects. And can obtain good economic benefit, social benefit and environmental safety benefit. Through the study on the economic evaluation of coalbed methane (CBM) extraction projects in coal mine area, its economic evaluation index and economic evaluation model can be used for reference to similar projects in the future.
