摘要

通过研究王营―刘家区煤层气地质特征和分析向斜构造的力学特性及其对煤层气的控制作用,认为向斜构造是该区煤层气的主控因素。向斜上层渗透率和含气量较低,对渗透率和含气量相对较高的下层起到封盖作用;向斜下层渗透率和含气量较高,所以煤层气的勘探和开发应以向斜下层煤层为主要目的层进行。

Abstract

Through the study of the geological characteristics of coalbed  methane in Wangying-liujia district, The mechanical properties of syncline and its controlling of coalbed methane is analyzed. It is illustrated that the  syncline is the main controlling factor: the permeability and gas content of the superstratum of syncline is much lower, so it closes over the underlayer of  syncline whose permeability and gas content is higher. Therefore, prospecting and exploitation of coalbed methane should be carried through seams in which lies  in underlayer of syncline. 
