【摘要】 在分析了采用地震相技术预测煤层气含量可行性的基础上,首先利用无监督向量量化网络对研究区地震资料进行了地震波形划分,然后在钻孔实测煤层气含量值的指导下,依赖地震波形特征反演与煤层气含量有关综合特征,完成了使用地震相分布图对勘探区煤层气含量的预测。预测结果与实测值相符,具有较高的预测分辨率,从而证明了该方法的有效性和实用性。更多还原

【Abstract】 This paper analyzed the feasibility of applying seismic facies technology to forecasting coal-bed methane content.The authors first made seismic wave division in the study area by using unsupervised vector quantization network,and then completed coal-bed methane content prediction in the exploration area based on seismic facies under the guidance of the measured coal-bed methane values in drill holes and according to seismic wave characteristics.The results are consistent with the measured values and have relatively high prediction of resolution,suggesting that the application of seismic facies technology is an effective approach to predicting coal-bed methane content.更多还原
