METHOD FOR DEVELOPMENT OF OIL DEPOSIT WITH INTER-FORMATION FLOWS Russian patent published in 2020 - IPC E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, in particular, to development of oil deposits with flows of water and/or oil from different levels. Method includes oil extraction through production wells, water pumping through injection wells, liquid production, its watering and oil production measurement, identification of wells producing surplus water, well flooding sources, including comparative analysis of fluid production dynamics and its watering, and performing works on specification of watering source with comparison of parameters of formation energy state and/or intensity of hydrodynamic impact on formation. In the presence of overflow between the water-bearing and oil formations separated by the jumper, the pressure ratio of each of the formations is determined, at which production of oil formation is at least per meter included in interval of web for creation of natural screen, which prevents water breakthrough from water-bearing stratum into oil reservoir. Producing wells communicated with water-bearing and oil reservoirs, respectively, it is equipped with deep-well pumps with controlled extraction and reservoir pressure sensors for continuous control and regulation of product withdrawal from appropriate wells, which enable to maintain natural screen within the jumper and limit excess water production from oil reservoir.

EFFECT: development of a method for development of oil deposit with inter-river flows, which allows to work with formations, in which parameters of formation with time, and parameters, which are controlled in real time from modes of extraction and/or pumping through formations, conducted on the basis of measurements.
