摘要：
The problem on oil filtration in the reservoir model with the preset differential pressure harmonically varying in time on its faces is solved. Hysteresis effects of capillary pressure under change in the direction of fluid expulsion are considered. The influence exerted by liquid fluctuations on cleaning the near-well zone from possible capillary blocking of aqueous phase is estimated. The action of alternating pressure pulses on the oil-saturated reservoir model is investigated. It is shown that harmonic change in liquid pressure promotes removal of immobile capillary-blocked water from the near-well zone. The results of in-situ experiments on wave action on the wellbottom zone and oil production stimulation are presented.
