论文中文摘要: |
煤层气是一种潜在的巨大资源,是二十一世纪绿色环保能源。在我国煤层气资源主要集中在晋陕蒙,其中鄂尔多斯盆地比重最大。鄂尔多斯盆地东缘煤层埋深适中,渗透率较高、煤层厚、含气量高,以肥、焦煤为主,有少量贫、瘦煤,具有适合煤层气开发的优质地质条件。
本文针对研究区煤层储气与产气性能的独特性和复杂性,基于地球物理测井基本原理和现代信号分析处理技术,利用研究区的地质资料、煤岩心资料、测井资料和生产动态资料等,分析了含气量测井响应特征、渗透率测井响应特征以及其他参数测井响应特征,在优选煤层气储层参数评价指标的基础上,采用非线性数学方法构建煤层气储层测井综合评价模型,进而对研究区煤层气储层高渗富集区进行预测,以期合理高效开发研究区的煤层气。

论文外文摘要: |
CBM is a potential huge resource, a green environmental energy in 21st century. In China it is mainly concentrated in the Shanxi province, Shaanxi province and Mongolia, in which the proportion of ordos basin is the largest. Coal bed is thickness and burial deep is moderate in eastern fringe of Ordos basin, permeability and gas content are higher. It depends on fat coal and coking coal mainly, has small amount of lean coal and meagre coal, and is suitable for high-quality geological conditions of the CBM development.
According to specificity and complexity between gas-storing property and gas production performance in coal reservoir, based on the basic principle of geophysical well logging and the modern signal analysis and processing technology, and using data of geological, coal core, logging and production dynamic, this article analyzes the logging response characteristics of gas content, permeability and the other parameters, uses non-linear mathematics method to establish logging comprehensive evaluation model of CBM reservoir on the base of optimum seeking comprehensive evaluation index of reservoir. And then to forecast the high-permeability accumulation regions of CBM reservoir in research area in order to explore research area CBM reasonably and efficiently.
