1) coal bed methane index
煤层气指标
1.
Experiment on test well of coal bed methane index based on injection pressure drop method;
基于注入压降法的煤层气指标试井试验
2) gas marker of coal spontaneous combustion
煤自燃指标气体
3) CBM perspective
煤层气目标区
1.
The evaluation of CBM perspectives affects the exploration results and it is the basic work for CBM exploration,so it is highly necessary to conduct comprehensive analysis and evaluation on Chinese CBM perspectives.
本研究在大量收集煤层气资源基础材料和借鉴前人研究成果的基础上,从地质背景、煤储层、资源以及开发基础等4个因素出发,确定了煤层气矿区评价参数选择标准,建立了煤层气目标区资源评价指标体系,采用无量纲化指标处理并通过层次分析法对中国煤层气矿区进行资源优选排序,确定了中国煤层气开发优选目标及不同优选层次。
4) grey association cluster
煤层气层
1.
Based on the principle of grey association analysis,the present paper has put forward a fairly practical and readily programmed cluster method—grey association cluster method,and employed this method to demarcate coal beds and gas beds,discriminate between coal-produced gas bed,oil bed and water bed ,and make lithostratigraphic classification.
基于灰色关联分析原理 ,提出了一种较为实用且易于编程的聚类方法 ,即灰关联聚类法 ,并应用该方法标定煤层气层 ,识别煤成气层、油、水层和划分岩
5) the coal-level indicators
煤级指标
1.
Because of the complexity of the coalification process and the diversity of the coal-level indicators,it was induced that resulting in different coalification stages the coal-level indicators were significantly different and coal-division was rather difficult.
煤化过程的复杂性和煤级指标的多元性,导致不同煤化阶段中的各煤级指标显著不同,煤级划分比较困难。
6) Parameters of coal properties
煤质指标
1.
Some parameters of coal properties which are not a linear combination of the individual index in weight of blending coal, such as Hardgrove grindability index (HGI), screen analysis, ash fusibility, ect.
从煤在不同类型锅炉的燃烧方式出发，讨论了煤质特性对燃烧工况及对环境的影响，以及一些非加和性煤质指标，如可磨性、粒度组成、煤炭熔融性等对动力配煤的影响，进而提出选定动力配煤方案的原则。
