| Abstract: | The theoretical basis of subdivision interpretation in total gamma logging is the theory of gamma field in borehole, which is very important in uranium exploration. Now there is only the theory of gamma field in vertical borehole. So total gamma-ray logging curve of vertical borehole can be interpreted by subdivision interpretation (except deconvolution). The author presents the theory of primary gamma field in slant borehole. At the same time, the nature of gamma field in slant borehole and D function as well as the relation between D function and other gamma field functions are discussed, and then the problem on the calcula- tion of shape coefficient of slant borehole is solved. |
