摘　　要：在只有少量钻井且地层速度变化较大的地区，钻孔处的声波测井数据不能反映研究区内的速度变化规律，为此提出了一种新的速度岩性量版——速度频率岩性量版，经与由测井数据制作的速度岩性量版对比分析，认为速度岩性量版只能代表钻孔处或邻近地区的地层速度随深度变化规律。速度频率岩性量版能更好地反映整个研究区内地层速度随深度的变化。Data from sonic logs in drilled holes can hardly reflect the law of velocity change in a study area where there is few of drillings and a great lot of changes in layer velocity A new velocitylithographer map,that is, velocity frequencylithographer is developedCompared with the velocitylithographer map made by sonic logs representing the law of velocity's change with depth, the new map is capable of reflecting the above law in the study area By means of the new map,the reservoirs in member 1 of Dongying formation in Yuedong structure, Liaohe basin are forecasted horizontally
