摘要:The hydrodynamic model (HDM) is a tool for designing the development of oil fields, calculating the efficiency of geological and technical measures (GTM) and performing predictive calculations of development indicators for a long period. A method had been developed for correcting the values of the permeability cube during the adaptation of the hydrodynamic model, taking into account the relationship between the petrophysical properties of rocks according to the core study data. The technique was applied to the example of a deposit of the Bobrikovsky formation (terrigenous reservoir) of one of the deposits of the Solikamskaya depression. The work carried out a statistical analysis of the reservoir properties of the Bobrikovsky reservoir according to the results of the interpretation of well logging and according to the hydrodynamic model; the differences between the initial permeability obtained after rescaling of the geological model and the permeability after HDM adaptation were considered. As a result of the analysis, discrepancies in the statistical characteristics of the permeability values according to the interpretation of well logging and in the hydrodynamic model were revealed, as well as significant differences in the cubes of the adapted and initial permeability. It was found that in the model setting process, the initial permeability was significantly modified by the "manual" adaptation method. Revealing and correction of permeability extreme values were performed on the basis of the petrophysical dependence KPR = f (KP ) from the core, taking into account the ranges of variation of the porosity and permeability coefficients. Using a modified permeability cube, calculations were performed to reproduce the development history of the object. Based on the results of the calculations, convergence with the actual data was achieved, the deviations meet the requirements for the accuracy of the model adjustment. Thus, this method of correcting the permeability cube after "manual" adaptation of the model will allow to avoid significant overestimations or underestimations of permeability in the cells of the hydrodynamic model.
