含瓦斯煤等压渗吸实验研究及工程应用
Strdy and Engineering Application of Isobaric Imbibition Test Based on Coal Containing Gas
摘要
Abstract
In order to change the phenomenon of mining tension after the implementation of permeability improvement measures for low permeability coal seam,inspired by the oil displacement by imbibition mechanism of oil and gas reservoirs in the field of oil and gas reservoir mining,by building the experimental platform,under the constant pressure of the experimental system,the study on the effect of imbibition was conducted.The experimental results show that after water enters the coal,adsorption of gas in coal can he replaced to promot gas desorption;both the maximum amount and rate of imbibition have a positive correlation with water content.However,the difference between the adjacent points decreases with the increase of water content.In the initial stage,the speed increases quickly.Combined with the experimental study,a new method of using imbibition effect as supplementary measure to promote gas drainage in the late period is proposed.关键词
