- Abstract
We have undertaken a theoretical study of the hydrodynamics of fluid motion in communicating vertical pipes with different forms of vibrowave effect in the wellhead. The dynamics of the propagation of elastic waves and pressure in the zone of fluid crossflow from one pipe into the other has been examined. The character of change in the bottom-hole pressure has been determined. It is shown that in the case of a sawtoothedchange in the pressure of the fluid pumped into the wellhead, the variation in pressure in the zone of fluid crossflow from one pipe into the other occurs in the form of beats.
