FILTRATION MODEL OF OIL CONING IN A BOTTOM WATER-DRIVE RESERVOIR

Abstract

The purpose of the paper is the substantiation of the application of the oil coning technology in the process of the hydrodynamic simulation of the successive method, which includes the perforation of the casing below the level of oil-water contact; the drawing of water from the lower water-saturated part of the reservoir; the isolation of this perforation interval; the drilling-in of the near-caprock oil-saturated part of the reservoir and the production of near-caprock oil. The leading approach to the research of this problem is the method of filtration modeling of the oil and water coning processes in the reservoir. As a result of the study, a hydrodynamic model of a well has been created, which corresponds to the requirements of the visualization of the process, the authenticity and the possibility to control the necessary parameters of the model and to estimate the effectiveness of the technology.
