摘　　要：曲堤地区煤层发育 ,是胜利油区最有潜力的煤成气勘探目标之一。该区钻井资料较少 ,煤层的横向厚度难以控制 ,其资源量计算有困难。根据不同岩层的地震属性及本区煤层发育特点 ,尝试了利用地震瞬时振幅、瞬时相位和瞬时频率信息计算煤层厚度。The coal seam in Qudi area is developed, and it is one of the exploration targets of the coal formed gas of great potentiality in Shengli petroliferous province. It is difficult of controlling the lateral thickness and calculating the resources of the coal seam for few drilling data. It is tried that the instantaneous amplitude, instantaneous phase and instantaneous frequency of seismic information are used for calculating the thickness of the coal seam based on the seismic attribution of various rock formations and the developed characteristics of the coal seam in this area. The calculated results tally well with the thickness of the coal seam known by drilling.
