Способ разработки нефтяного месторождения на заключительной стадии с помощью установления форсированного режима отбора жидкости, включающий доизвлечение нефти с использованием существующего фонда скважин за счет установления на них отбора по жидкости, кратно превосходящего предшествующий отбор, отличающийся тем, что форсированный отбор жидкости осуществляют на скважине, выбранной из числа скважин, расположенных в прикупольной зоне, которая находится ближе других к предполагаемой максимальной абсолютной отметке на куполе, причем устанавливают режим отбора жидкости, позволяющий создать градиент давления, который превышал бы предшествующий градиент давления на величину
dP/dL ≥ Δγ•H,
где dP - разница между давлением на входе в антиклиналь и давлением в точке, которая является проекцией максимальной отметки на горизонтальную плоскость;
L - расстояние между точками с известными значениями давления;
Δγ - разница в удельном весе между пластовой нефтью и водой;
H - высота, равная разнице между максимальной отметкой на куполе и границей раздела нефти и воды до применения форсированного отбора жидкости.A method of developing an oil field at the final stage by establishing a forced mode of fluid extraction, including re-extraction of oil using the existing well stock by establishing a fluid selection that is several times higher than the previous selection, characterized in that the forced selection of fluid is carried out at a well selected from the number of wells located in the near-dome zone, which is closer to the estimated maximum absolute mark on the dome, and tanavlivayut fluid selection mode that allows you to create a pressure gradient, which would exceed the previous value of the pressure gradient on
dP / dL ≥ Δγ • H,
where dP is the difference between the pressure at the entrance to the anticline and the pressure at the point, which is the projection of the maximum elevation on the horizontal plane;
L is the distance between points with known pressure values;
Δγ is the difference in specific gravity between reservoir oil and water;
H is the height equal to the difference between the maximum mark on the dome and the interface between oil and water before the use of forced fluid withdrawal.
