滇东黔西煤层气选区及勘探目标评价

滇东黔西晚二叠世成煤期煤层气盆地发育,是华南重要的煤层气资源分布区,。本文概述煤层气盆地的划分与评价,提出煤层气系统的新概念,并对重点盆地进行研究。提出煤层气区带和煤层气地质风险分析的概念,并对滇东黔西地区重点区带进行煤层气藏预测及勘探目标优选,提出煤层气重点勘探开发试验区。

THE SELECTED AREA AND EVALUATION OF EXPLORATION TARGET OF SEAM GAS IN EAST YUNNAN AND WEST GUIZHOU

In the late Permian coal-forming period, the basin of seam gas was developed in east Yunnan and west guizhou, which are the important areas of seam gas resources in South China. In this paper, we outline the classification and evaluation of the basin of seam gas, put forward the concept of seam gas system and study the emphtic basin. The zonation of seam gas area and the concept of geological risk analysis of seam gas are put forward. The seam gas resources prognosis and exploration target selection in the emphatic area and zone are carried out. The emphatic exploration-exploitation experiment area of seam gas and the evaluation of the exploration target of seam gas in east Yunnan and west Guizhow are put forward.
