【摘要】 煤厚预测的传统方法是利用钻孔资料内插而成,在很大程度上受到钻孔密度的限制且精度低。从薄层理论出发,利用常规三维地震资料并采用钻孔约束,在频率域对煤层的厚度进行了定量预测分析。通过实际资料应用,证明该方法预测精度较高,取得了令人满意的地质效果。更多还原

【Abstract】 The traditional method of coal—layer thickness prediction is to use the inside interpolation be- tween the boreholes,which depends on the density of boreholes and whose precision is very low.Based on the analysis of thin—layer theory and conventional 3D seismic data and constrained by borehole data ,the coal layer thickness is quantitatively predicted in this paper.The application reveals that we have gained a high—precision and achieved a satisfactory result.更多还原
