Mathematical model as a means of predicting effectiveness of well intervention for near-wellbore space

Abstract

Abstract The conclusion about the appropriateness of using this or that type of well intervention equipment should be based not only on the technological and economic efficiency but also on a mathematical model. The existing geological and field restrictions for the selection of impact objects for each type of well intervention should not also be overlooked due to the fact that in this case the use of a mathematical model is more appropriate. A fundamentally new method of multifunctional regressive mathematical modeling for evaluating the technological efficiency of processing the bottom-hole zone with an increase in the oil recovery coefficient is described. A new algorithm for determining the dependence of the technology efficiency is proposed, the obtained multivariate regression model is checked for statistical reliability and significance, the forecast for the increase in oil recovery coefficient is calculated
