This paper is dedicated to mathematical modeling of oil treatment quality indicators. The system developed by the authors uses the results of measurements done with the instruments that the oil treatment unit is equipped with as the initial data for the modeling. In this regard, the effect of instrument measurement accuracy on the accuracy of prediction of crude oil quality indicators is relevant. The coefficient values of the effect of instrument measurement accuracy on saturated vapor pressure of the crude oil were estimated using a mathematical model of a typical oil treatment unit. It was shown that the prediction accuracy was most affected by the accuracy of measurements of temperature and gas consumption at the last separation stage.
