Dong Y., Wu C., Guo H., Lv Q., Li H., 2015, A New Interpretation Model for Transit Time Based on Impulse Oxygen Activation Logging Data, Chemical Engineering Transactions, 46, 13-18.
Aiming at the interpretation problem for impulse oxygen activation logging data, the number of the peak shape functions which are used to fit the interpretation model is very large and the logging interpretation accuracy of the function is low. And the accuracy of the weighted average interpretation model is also low. This paper presented an indirect method of selecting spectral peak. And it gave a new transit-time interpretation model. The specific operations are described as follow. Firstly, the background spectrum was chosen manually. And then several spectral peaks were determined according to the given rules. Finally, the determined spectral peak sections were substitute into the established transit-time interpretation model, and then the volume flow rate was calculated. The processing results of the measured data showed that the effect of the selecting methods of background spectrum on the interpretation results of interpretation model is very small and the interpretation accuracy is higher than the one of the existing model.
