【摘要】 世界常规能源紧张局面不可避免，一些国家已经开展了煤层气、油砂矿、水溶气和油页岩等非常规资源的开发与利用工作，并取得了巨大的成功，获得了可观的经济效益和社会效益。为了促进中国煤层气资源储量计算与评价工作，为我国日益兴起的煤层气资源储量评价工作提供可供借鉴的技术和方法，本论文在深入研究煤层气成藏与富集、资源储量评估基础理论与方法等基础上，结合中国现有煤层气资源储量地质条件的特殊性，开展了系统的资源储量评估方法和实践研究，首次提出了现阶段井点控制法是计算煤层气储量的适用方法。主要成果如下：1．提出了我国目前煤层气资源储量评估方法的技术框架，系统地建立了我国煤层气资源储量分类分级体系。煤层气的储量评估不仅要重视技术条件和经济效益，更应该重视煤层气藏的钻探情况、试采情况以及开采计划，这样才能保证各级各类资源储量具有合理的确定性。2．鉴于煤层气资源储量具有固体矿藏与流体矿藏的特殊性，首次提出了井点控制法，它是勘探评价阶段计算煤层气资源储量的最佳方法。井点控制法的边界条件受煤层本身特征和开发生产特点共同制约。井点控制法确定的各级储量含义，与国际通行的标准基本一致。3．规范了井点控制法储量计算参数的确定原则和选值要求，提出了计算煤层气技术可采储量和经济可采储量的基本方法，为建立新的符合中国地质条件的煤层气储量计算规范奠定了坚实基础。4．建立了煤层气资源储量综合评价方法，对优选有利勘探区、计算煤层气经济可采储量以及煤层气项目经济评价，具有一定的指导意义。5．利用井点控制法计算了中国沁水盆地ZZ区块煤层气探明储量，储量计算结果和储量计算参数的求取与选值，为我国煤层气资源储量评估与评价提供了可供借鉴的实例。更多还原

【Abstract】 As the existing conflicts between the consumption and supply of the conventional oil and gas will be inevitably aggravated, many countries have devoted their attentions into the development of unconventional energy sources such as coalgas, tar sands, water solution gas as well as oil shales, and have achieved considerable economic and social benefits. In order to promoting the estimation and appraisal of Chinese coalgas resources and reserves, this dissertation illustrates systematically coalgas reserves estimation methods and their applications which considered China’s special geological setting for coalgas reserves. Especially, this dissertation put forward a new reserves estimation technique named "coalgas well controlled method". The achievements and conclusions by this dissertation are listed as following:i. The technical framework for Chinese coalgas resources and reserves estimation methods has been built, and also a comprehensive classification system on coalgas resources and reserves has been established. In order to keeping the reasonability of coalgas resources and reserves, the current technical and economical conditions should be well considered, particularly, the drilling information, production tests and developing plan.ii. A new technique named "coalgas well controlled method" for coalgas reserves estimation has been put forward which can be regarded as the most suitable method during the stage of exploration. This method balances particularities of coalgas reservoir as a solid reservoir as well as a fluid reservoir.iii. Rules about the acquisition of various parameters for the "coalgas well controlled method" are presented in detail. What’s more, the basic methods for technical and economic recoverable reserves are also introduced. These provide a firm foundation for new standard of coalgas reserves estimation work in China.iv. A comprehensive appraisal method has been built, which bring some help in the work of optimal prospecting area choosing, economic recoverable reserves calculation as well as the economic evaluation work for coalgas projects.v. Coalgas reserves estimation in ZZ Block of Qinshui basin has been done using the "coalgas well controlled method". This study will provide a good referential case in coalgas reserves estimation and appraisal in China.更多还原
