【摘要】 为了准确对煤层含气量进行预测,以新景矿区3~#煤层为研究区,利用测井岩石物理分析的方法,对煤层含气量与多种物性参数进行交会分析,筛选出与含气量相关性高的参数,并得到与含气量的线性关系。在此基础上,利用叠后反演的方法,得到3~#煤层的纵波阻抗数据体,最后结合含气量与密度和纵波速度之间的线性关系,实现了3~#煤层含气量的预测研究,预测结果与实测值比较吻合。更多还原

【Abstract】 In order to accurately forecast coal seam gas content, regard the Xinjing mining area No.3 coal seam as the research target, and log gas physics analysis method was used to analyze the coal seam gas content and various physical parameters, select the parameters of the correlation between air content and high, and a linear relationship with the gas content. On this basis, the post-stack inversion method was used to obtain the longitudinal wave impedance data of No.3 coal seam. Finally, the linear relationship between the gas content, density, and the longitudinal wave velocity was used to realize the prediction and prediction of the gas content of the No.3 coal seam. The results are in good agreement with the measured values.更多还原
