摘　　要：利用合成地震记录标定反射波地质属性,采用多元多项式拟合速度进行空间归位,控制煤层底板的起伏形态。采用钻孔约束波动方程反演波阻抗,结合钻探资料及合成记录,分析煤层反射波特点和类型以及与波阻抗剖面和煤层宏观结构的关系,解释了煤层厚度及煤层结构。初步控制了煤层起伏形态和煤层宏观结构及煤层厚度变化规律。Synthetic seismic records were used to calibrate the geological attributes of reflected wave, and multivariate polynomial fitting velocity was used to carry out spatial positioning, so as to control the relief form of coal floor. Based on drilling data and synthetic records, the reflection wave points and types of coal seam and the relationship between wave impedance profile and macro structure of coal seam are analyzed, and the thickness and structure of coal seam are explained. The undulating shape,macroscopic structure and thickness of coal seam are preliminarily controlled.
