ИССЛЕДОВАНИЕ ЭФФЕКТИВНОСТИ ЦИКЛИЧЕСКОГО ВОЗДЕЙСТВИЯ НА ЗАЛЕЖЬ НЕФТИ В С-VI ПЛАСТЕ НА АШИТСКОМ УЧАСТКЕ АРЛАНСКОГО МЕСТОРОЖДЕНИЯ

Background The work is devoted to the study of the effectiveness of cyclic impact on the reservoir deposits of the C-VI Ashit experimental site of the Arlansky oil field. Changes in hydrodynamic pressure during cyclic exposure are taken into account. At the present stage of the development of oil fields it’s necessary to use all promising methods for oil recovery increasing. One of the known methods is still a hydrodynamic method of influence on the reservoir. In this regard, the calculations of the cyclic impact on the reservoir require additional calculation refinements, resulting in reservoir replacement by a two-layer model. Aims and Objectives To calculate the effects of this impact on the studied reservoir using a two-layer model. Results The elastic-capillary cyclic method of waterflooding is based on a periodic change in the conditions of exposure to heterogeneous reservoirs, in which an unsteady distribution of reservoir pressure is created and an unsteady movement of liquids and gas occurs. To study the effectiveness of the cyclic impact on the oil reservoir on the example of the Ashit area of the Arlansky oil field, a two-layer model consisting of a water-cut and oil-saturated layer is considered. The model considers the behavior of the deposit when exposed to a pressure pulse. The total interlayer fluid flow from the non-watered and flooded layers is calculated. Calculates the parameters of the equipment required for cyclic exposure. The paper concludes that it is possible to apply a cyclic impact on the C-VI stratum of the Ashtitsky experimental section of the Arlansky field in order to increase oil recovery.
