黄陇煤田煤层气储层特征
Characteristics of CBM reservoir in Huangling-Longxian coalfield
摘要
Abstract
Based upon large amounts of measurement data of desorption and well test, studies of the reservoir pa-rameters such as the gas content, the permeability, the reservoir pressure, the minimum principal stress in Huan-gling-Longxian coalfield were conducted. The results show that the gas content and the permeability are relatively high, the ground stress is relatively low, the gas content, the reservoir pressure and the minimum principal stress are positively correlated to the burial depth of coal seams, the permeability and the minimum principal stress are nega-tively correlated, relationship between the permeability and the seam depth is not obvious, the influence of the minimum principal stress on the reservoir pressure is evident. From the integral analysis, it is considered that Binxian and Jiaoping mining area with relatively high CBM content and permeability are favorable block for CBM exploitation.关键词
