【摘要】 基于地震AVO反演原理和方法,针对已知的煤与瓦斯突出点进行了AVO反演。单点分析发现,煤与瓦斯突出点处的偏移距—振幅拟合关系的截距和梯度绝对值比非突出点大,表明煤与瓦斯突出点能引起地震AVO响应异常。依据突出点处的地震AVO响应特征,通过交会分析和综合指标分析,可实现对煤与瓦斯突出区的预测。但是,作为一项新的预测技术,在实际应用中要结合区域地质综合分析,以避免AVO反演结果的多解性。更多还原

【Abstract】 Based on principle and method of seismic AVO inversion,the inversion for some known coal-gas outburst points is integrated.Single point analysis shows that the absolute AVO intercept and gradient at the coal-gas outburst point is greater than that at the non-outburst point,suggesting that the AVO abnormity would be resulted from coal-gas outburst points.According to AVO response at the coal-gas outburst points,the prediction of coal-gas outburst area is gotten by AVO crossplot and integrative index.As a new predicting technology,the comprehensive analysis of the regional geology should be involved practically so as to avoid the multi-solutions of AVO inversion.更多还原
