METHOD OF OIL WELL DEVELOPMENT WITH IMPULSE WATER WITHDRAWAL REGIME Russian patent published in 2009 - IPC E21B43/20 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production can be used for oil reservoir production with impulse water withdrawal through production wells. Method includes allocation locally lifted areas of production reservoir and execution impulse water withdrawal through production wells on this areas. According to the invention, impulse water withdrawal executed on the initial and at later production stages. For impulse water withdrawal regime used production wells with product water content greater than 60%, with reservoir high production rate and with high static and dynamic levels of hole clearance fluid. Production of production wells executed in impulse regime on the initial and at later production stages, for impulse regime used production wells with product water content greater than 60%, with reservoir high production rate and with high static and dynamic levels of hole clearance fluid. For each well determine maximal possible hole clearance level decrease up to technically possible. After that withdraw liquid with simultaneous dynamic level recovery from maximum decreased till steady-state level. At every well execute impulse water withdrawal till complete flooding or profitable production rate.

EFFECT: oil production rate increase.
