煤田采区火成岩分布地震反演技术的应用研究

将基于模型的地震反演技术应用于国桩采区地震资料岩性解释过程中．首先对基于模型的地震反演原理进行了阐述，并针对煤田测井数据特点进行了数据处理与分析，然后对地震子渡进行了分析提取，实现了精细的火威岩的层位标定．通过对国桩采区的火成岩及煤系地层进行的综合地质分析，利用地震反演技术实现了火成岩与煤系地层的薄层分布信息预测．结果表明，该方法有效的提高地了地震数据的分辨率，能解释常规剖面上不易识别出的一些地质现象，为采区火成岩的分布，薄煤层的开采、有利区带的评价提供详实的信息。

Application of Seismic Inversion Based on Model for Igneous Distributing in Coalfields

The technology of seismic inversion based on model was used for lithology prediction and interpretation in Guozhuang coalfield.The theory of seismic inversion based on model was expatiated and the well logging data was analyzed.The seismic wavelet was analyzed and extracted from the data,and the elaborate igneous rock layer demarcation was realized.Based on the synthetical analysis,the distribution information for igneous rock and thin layers in coal-bearing series was forecasted.The result indicates that this method can improve the resolution of seismic data effectively and interpret some geological phenomena which can't be recognized in ordinary seismic section,and provide reliable data for igneous rock distribution,thin seam exploitation and favorable area evaluation.
