【摘要】 通过多年的实践,从煤层气赋存特征、煤层气地质学理论出发,分析煤层气与天然气的根本区别。通过对天然气AVO理论的取舍,重建了煤层气AVO技术的岩石物理理论,保留了天然气AVO技术的地震波理论外壳,建立了煤层气AVO技术的地震波理论基础。将煤层气AVO技术的岩石物理基础和地震波理论基础应用于煤层气勘探开发实践中,在煤层气局部富集区预测实践中取得了较好的应用效果,实现煤层气勘探开发从"以工程为主导"到"预测指导下的工程"之转变。更多还原

【Abstract】 Based on practices in many years,starting from CBM occurrence features and CBM geological theory,analyzed basic differences between CBM and natural gas.Through accept or reject of natural gas AVO theories,reestablished CBM AVO technique petrophysical theory,kept down natural gas AVO technique seismic wave theoretical outer covering,established CBM AVO technique seismic wave theoretical basis.Taking petrophysical basis and seismic wave theoretical basis of CBM AVO technique applied in CBM exploration and exploitation practices,preferable applying effects have been acquired in CBM local enrichment area prediction,and realized the transformation of CBM exploration and exploitation from "project dominant" to "prediction guiding project".更多还原
