贵州关岭花江背斜勘查区煤层气富集特征与开发潜力评价

Study on Coalbed Methane Enrichment Characteristics and Development Potential Evaluation of Huajiang Anticline Exploration Area in Guanling of Guizhou

系统地分析贵州关岭花江背斜勘查区的基本地质条件,初步评价煤层气的开发潜力,并通过制定有利区的评价标准,确定了下一步勘探开发的目标区域。研究结果表明:在煤层厚度、埋深的共同影响下,区内主要可采煤层含气量总体呈现以花江背斜轴为中心向两翼逐渐增大的规律性。综合认为有较好煤层气赋存条件的有利区Ⅰ和有利区Ⅱ是下一步勘探开发的重点区域。

Through analysis of the basic geological conditions of Huajiang Anticline Exploration Area in Guanling of Guizhou Province,the paper preliminarily evaluates the development potential of coalbed methane,and determines the target area for exploration and development in the next step through setting up evaluation standards of favorable areas.The results show that on the influence of thickness and buried depth,the gas content of the main coal seams in the area increases from the axis of Huajiang Anticline as the central point to both wings.It is considered that the favorable areas I and favorable areaⅡwith better coalbed methane occurrence conditions are the key areas for the next exploration and development.
