【摘要】 针对一些特殊矿区因钻孔数量稀少、不能实现三维地震资料有效解释的情况,利用地质模型的正演模拟,提出一种地震反射波地质层位涵义标定方法及时-深转换方法,预测吉新煤矿煤层底板深度。钻探与巷道资料验证结果表明,6#煤层的底板深度为489 m,与文中方法预测结果吻合;正演模拟技术能够正确指导地质层位标定,叠加速度体的充分利用有效提高了底板标高精度。更多还原

【Abstract】 Aimed at overcoming the failure to interpret 3D seismic data effectively due to fewer boreholes in some special fields,this paper,based on the simulation of geological model,proposes the calibration method for corresponding geological layer meaning with the seismic reflection and time-depth conversion and the prediction of coal floor depth of Jixin coal mine.The real drilling and roadway data verify that 6# coal floor is 489 m deep,consistent with the prediction results produced by the proposed way.The forward simulation technique allows the correct calibration for geological horizon and the full utilization of staking velocity volume enables an effectively improved interpretation precision of coal floor depth.更多还原
