Impulse non-stationary flooding of hydrocarbon deposits

Pulse method of non-stationary flooding is a continuous regulation process. Its efficiency is determined by the reserve recovery stage and is chosen after thorough analysis of the development, when the oil deposits are determined differentially on the field zones and deposits and there is a positive forecast of their extraction by existing methods. Then comparing development parameters of different variants of pulse non-stationary flooding the best development method is chosen. In this case bottom-hole or well head devices (energizers, shaker apparatus, pulsators etc.) are used for pulse flooding in order to boost reverse capillary imbibitions of closed oil zones and reversal filtration of the injected water. Experiments showed, with the increase of vibration frequency at the given parabolic law of pressure deviation fluid penetration rate into the fractured-porous layer increases sharply. Preliminary results showed high efficiency of selective application of complex flooding of hydrocarbon deposit.
