沁水盆地南部煤层气叠前地震多属性分析

Analysis of Pre-stack Seismic Multiple Attributes Applied in Coalbed Methane Prediction in Southern Qinshui Basin

将叠前AVO属性、叠前AVO反演、叠前FVO反演同时应用在沁水盆地南部3#煤层的储层预测中,综合分析叠前地震多属性,确定有利储层分布,预测结果与实际测井解释的含气性结论一致,有效地提高了煤储层预测的准确性,且为沁水盆地南部煤层气及类似储层的预测提供可行的方法。

Using pre-stack AVO attribute,pre-stack AVO inversion and pre-stack FVO inversion predicts combed methane in this region. Analying pre-stack seismic multiple attributes and determining favorable reservoir distribution. Predicted results are consistent with the real logging results and better than reservoir prediction in terms of predication accuracy of coalbed methane. The method can be used by domain scientist to predict coalbed methane in southern Qinshui basin and other reservoir similar to Qinshui basin.
