METHOD FOR FORECASTING CHANGE IN PRODUCTION RATE OF PRODUCTION WELLS DURING PROPAGATION OF ELASTIC VIBRATIONS IN BOTTOMHOLE FORMATION ZONE Russian patent published in 2021 - IPC G01V99/00 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to intensification of oil production from terrigenous reservoirs by means of wave action on bottom-hole formation zone. Method includes stages: obtaining characteristics of productive formation, creation of three-dimensional mechanical model of geological medium based on characteristics of productive formation, designing the intensification using the created mechanical model of the geological environment, calibrating the intensification project based on actual data, simulating the projected intensification and predicting production, estimating the projected intensification. At the stage of creation of three-dimensional mechanical model of geological environment, modeling is carried out using a fine-scale mesh. At the stage of intensification design mechanical simulation of propagation of elastic oscillations on a fine-scale grid is performed; change of permeability to damping point of elastic oscillations in formation is determined, forecasting of change of yield of producing well after wave action is performed on large-scale grid.

EFFECT: technical result of the invention is higher accuracy of forecasting of oil production intensification.
