- W2355975099 abstract "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." @default.
