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。
The prestack AVO attributes, prestack AVO inversion and prestack FVO inversion are applied to the reservoir prediction of No.3 coal seam in southern Qinshui Basin. The prestack seismic attributes are comprehensively analyzed to determine the favorable reservoir distribution. The prediction results The gas-bearing conclusions of actual log interpretation are consistent, which effectively improves the accuracy of coal reservoir prediction and provides a feasible method for the prediction of coalbed methane and similar reservoirs in southern Qinshui Basin.
