摘　　要：用大庆地区４８口井的全波声波测井和密度测井资料建立了大庆地区密度与纵波速度、密度与横波速度经验公式．经５套文献数据和大庆、南阳、江陵等地实际测井资料检验证明，密度与纵波速度经验公式精度高于Ｇａｒｄｎｅｒ公式，并可看出误差的地区性差异；密度与横波速度经验公式无前人公式比较，但可看出其精度低于密度与纵波速度经验公式．建议在建立上述经验公式时，各地区最好根据本区资料确定经验公式中参数．如无本区公式可使用大庆经验公式．This paper, based on the full wave acoustic logging data and density logging data of 48 wells from Daqing, has built up two empirical formulas between density and P-wave velocity (DPV) and between density and S-wave velocity (DSV) relatively. The accuracy of DPV formula is higher than Gardner's formula after tested by five sets of data from papers and by some field well-logging data from Daqing, Nanyang, Jingling and so on, and the error is different in different area. There were no DSV formulas before so that no one can be compared with the DSV formula in Daqing, but the results have shown that its accuracy is lower than that of DPV formula. This paper suggests that when the formulas be used in different area, the parameters in them had better be determined by the correspondent field data. If there is no suitable formula for a particular area, the Daqing empirical formula may be taken into account.
