煤层气高产富集主控因素及预测方法

Main Control Factor and Prediction Method for the High Productivity Enrichment of Coal Seam Bed.

煤层厚度、含气量、解吸条件、渗透率、水文地质条件及工艺技术条件直接影响到煤层气高产能力。针对中国煤层气勘探现状 ,煤层气高产富集区预测要分两步走 。

The high productivity competence in the coal seam bed is directly effected by the formation thickness,gas content,desorption conditions,permeability,hydogeology condition and process condition.With the actuality of exploration of the coal bed methane in China,the high productivity enrichment area prediction shoud be divided into two steps,that is,the integration area selection and the high productivity enrichment area prediction.
