利用多波地震与测井数据联合反演预测煤岩的坚固性
|
摘要
基于煤岩的坚固性、变形模量以及纵、横波速度之间的岩石力学规律,提出用多波地震与测井数据的联合反演定量化预测煤岩的坚固性.根据煤田三维三分量地震采集的特点,建立了PP波与PS波平均入射角部分叠加道集的井约束反演流程;利用煤岩的坚固性系数与变形模量之间的换算关系对目标煤层的坚固性系数空间变化规律进行预测,并划分可能发生煤与瓦斯突出的区域.实际应用结果表明该方法可以为煤矿的安全生产提供有利的评价参数.
Based on the law of rock mechanics among the hardness,deformation modulus and P-and S-waves velocities of coal rock,quantitative prediction method of the coal hardness using joint inversion of multi-wave seismic data and logging is put forward.According to the characteristics of 3D3C seismic acquisition,the well constrained partial poststack gather inversion flow of PP- and PS-wave at average incident angles is established.The space variant hardness law of target coal strata is predicted according the transformation relationship between the hardness coefficients and the deformation modulus of the coal,and the area where coal and gas will outburst most probably is divided.Application result shows that the method could be selected to provide valuable evaluation parameter for the safe production in coal mine.
