Abstract: On the basis of the analysis of the wax deposition process, based on certain assumptions, the models of wax deposit thickness changes with time were established. By extracting the data of curve of wax deposition thickness with time, the given constants of the models were fitted, and coincidence degree of model calculation value and the experimental value was analyzed. The logarithmic model, exponential model and dynamic balance model could reflect the change trend of wax deposition thickness with time, the coincidence degree of logarithmic model and the experimental results was the best. For exponential model and dynamic balance model, the coincidence degree of model calculation value and the experimental value were much the same, in the initial stage of deposition, the coincidence degree of the exponential model was higher than the dynamic balance model, but when deposition time was closer to the experimental set time, the coincidence degree of the dynamic balance model was higher than the exponential model. The models were simple and practical, and they could also reflect the growth rate trend of wax deposition thickness change with time, the accuracy of each model should be further verified when the models were used for different experimental data, so that the selected models could be truthful and reliable.
