We developed a method for predicting the technological efficiency of geological and technological impacts carried out on the wells in order to regulate the development of oil deposits. The prediction of efficiency indicators is based on the method of numerical modeling of multiphase filtration flows of complex geometry in the near-wellbore space, which is based on the use of non-orthogonal irregular uncoordinated difference grids, describing in detail the features of hydrodynamic state changes in the near-wellbore formation zone as a result of the impact. As a result, using the obtained model, the most optimal development of oil and gas fields in complexly constructed reservoirs and interblock spaces is possible. The advantage is also the possibility of optimization of reservoir fluid production processes with input of additionally obtained data, which allows promptly responding to changes in filtration-volumetric properties of productive formations.
