摘　　要：为了评价海拉尔盆地煤层气的资源潜力，基于呼和湖凹陷煤层的实验数据探讨了利用测井资料评价煤层气的方法。采用岩心刻度测井法和体积模型法计算了煤层的工业分析组分，在此基础上建立了煤层组分与含气量的关系，进一步利用实验数据求取兰氏方程系数，通过等温吸附线估算含气量，进而采用测井资料计算的渗透率评估了煤层渗透性。应用结果表明，所建模型可用于评价研究区煤层的组分、含气量及渗透性，模型的计算结果与实验数据吻合较好。In order to evaluate the reserve potentials of coalbed methane in Hailar Basin, on the basis of the ex- perimental data of the coal seams in Huhehu Sag, the evaluating method by means of well logging data is explored. With the help of the methods of the logging calculated by cores and volume model, the industrial analyzing compo- nents of the seams are computed. Based on the above, the relations between the components and gas content are established, and moreover the coefficients of Langmuir Equation are obtained by means of the experimental data, by the adsorption isotherm, the gas content is estimated, finally the permeability property of the coalbed is predic- ted by the permeability calculated by the logging data. The practice show that the built model can be feasible to re- search the components, gas content and permeability of the coalbed. The evaluation of coalbed in the research area is achieved by the models established~ and furthermore there is much better coincidence between the calculated re- sults of the model and the experimental data.
