【摘要】 煤层气是一种以煤为生气源岩、又以吸附状态储存于煤层中的非常规天然气，是一种新型的洁净能源和优质化工原料，是未来的重要接替能源之一。煤层气俗称“瓦斯”，瓦斯是煤在地质历史演化过程中形成的气体地质体，其主要成分是CH4（甲烷)，热值是通用煤的2-5倍。我国传统的采煤法是只采煤不采气，不仅造成煤层气这种宝贵资源的严重浪费，同时还导致煤矿瓦斯事故的频发、空气中的碳排放量增加等多种安全、环境不利因素的产生。从国家石油安全战略角度看，煤层气较常规天然气乃至石油更具有战略意义，所以加强煤层气储层研究，对这种自生、自储型的非常规天然气展开攻关已势在必行。本文分析了准噶尔盆地阜康矿区煤层地质特征，煤矿主、副、风井的开拓工程揭露的矿井地质资料，详细地论述了决定了影响瓦斯赋存的三个主要要素：断层和褶皱，顶、底板岩性以及煤层埋深。根据对阜康煤田进行的地勘钻孔实测瓦斯含量、井下实测瓦斯含量和煤层埋深进行整理统计，分析其与埋深的关系，对42号煤层瓦斯含量与煤层埋深进行线性回归，并建立了相关的数学关系模型，来反映煤层埋深与煤层瓦斯含量的关系。采用体积法计算出阜康矿区井田范围内煤层气资源量和煤层气丰度值，最终得出阜康矿区的煤层总平面积约为33.47km2,煤层气地质储量15576.26Mm3，地质储量级别为中型级别；平均资源量丰度2.28×108m/km2，为中等类别。更多还原

【Abstract】 Coal seam gas is a kind of coal source rocks, and angry by adsorption state of stored in coal bed of unconventional natural gas, is a new type of clean energy and high quality chemical raw materials, is one of important sources of energy in the future. Coal bed gas, the gas is commonly known as "gas" in coal geological history evolution during the formation of gas geological body, its main component is the CH4(methane), calorific value of coal is a generic2-5times. China’s traditional mining method is not only coal gas, coal bed gas this invaluable not only caused a serious waste of resources, but also leads to the coal mine gas accident frequency, air emissions increased and security, environmental factors to produce. From the perspective of strategy of national oil safety, coal seam gas than conventional natural gas and oil has strategic sense more, so the strengthening of coalbed gas reservoir study, the self, self storage type of unconventional natural gas expansion research has be imperative.The paper analyzes the Junggar basin in Fukang Coal Mining geological features, coal mine owners, mine geological data revealed by the pioneering works of the Vice air shaft, are discussed in detail the three main elements affecting the methane occurrence:faults and folds, top, backplane lithology and seam depth.The measured gas content of the Fukang coalfield geological survey drilling, downhole measured gas content and seam depth statistical analysis and depth of the relationship, the No.42coal seam gas content and seam depth linear regression, and the establishment of the mathematical relationship model to reflect the relationship of the coal seam depth and seam gas content.The volume method to calculate the Fukang Coal Field within the coalbed methane resources and coal bed methane abundance values, concluded that the Fukang mine coal seam flat area approximately33.47km2coalbed methane reserves15576.26Mm3, the average resource abundance2.28×108m/km2for the middle class, helping improve the economic and social benefits.更多还原
