基于压力恢复曲线测定煤层瓦斯参数研究

Study on Gas Parameters of Coal Seam Based on Pressure Recovery Curve

结合煤层的赋存特点,首次将油、气田开发过程中压力恢复曲线的成熟理论和基本公式应用到煤层瓦斯赋存参数测定中,构建用于煤层瓦斯赋存参数测定的压力恢复曲线理论和方法,并在胡底煤矿进行了验证试验,用以指导瓦斯防治及煤层气开发等工作,具有一定的创新性。

Combined with the characteristics of coal seams, the mature theory and basic formula ofpressure recovery curve in oil and gas field development are applied to the determination of gasparameters in coal seam for the first time, and the theory and method of pressure recovery curve forcoal gas measurement parameters , and in the Hudi coal mine conducted a validation test to guide thegas control and coalbed methane development work, with a certain degree of innovation.
