| Abstract: | A quite ideal borehole diameter correction formula which has definite physical meanings has been developed by adopting geometrical factor method to make math- ematical fitting of Schlumberger Corporations borehole diameter correction chart for density logging data.Then the authors analyse the physical mechanism of how borehole diameter affects the velocity logging data which are collected by using the logger that has one transmitter and two receivers.Then corresponding correction formula and correction chart are given in the paper.Finally,the correction effect is illustrated here. |
