METHOD OF DEVELOPING OIL DEPOSITS Russian patent published in 2016 - IPC E21B43/20 

FIELD: oil industry.

SUBSTANCE: invention relates to oil industry and can be used in development of a non-homogeneous oil deposit. Method involves distinguishing at the deposit of sections with different permeability. It is necessary to allocate the boundary between sections with low and medium permeability. An inert part of the deposit along the selected boundary is involved in development. For this purpose, there is analysed the history of the given part of the deposit, determined the volume of working agent pumped currently into every injection based on withdrawal of oil by the production well at the section with middle permeability. Taking into account the compensation of withdrawn oil due to injection of working agent, there is determined an inert part of the deposit - the uncovered zone of oil deposits near the distinguished boundary for compaction of the well pattern. Well pattern compaction is made by drilling of an additional production well at the section with middle permeability near the boundary between sections with low and medium permeability in the interval between neighbouring injection wells. During drilling of the additional production well there are registered factors resulting in flowing, - formation pressure and gas factor. Working agent is pumped through injection wells and bed products are recovered through production wells.

EFFECT: technical result - increase of the deposit oil recovery factor.
