METHOD FOR FLUID OSCILLATION EXCITING IN WELL BOTTOM ZONE |
摘要 |
FIELD: mining, particularly producing well development or reworking, particularly to stimulate fluid inflow. ^ SUBSTANCE: method involves placing weight connected to suspension means in pipe string filled with fluid and exciting oscillations by axial weight movement. Resilient suspension means is connected to sucker-rod pump inlet. The resilient suspension means is high-pressure hose provided with metal woven sleeving and having elastic characteristics exceeding that of sucker-rod pump rod. The resilient suspension means provide weight oscillation in resonance regime. Weight is connected to high-pressure hose so that weight is in influence zone of liquid jet moving via hose during sucker-rod pump operation to provide wave fluid flow inside well, to create periodical pressure drops in perforation zone and to strike string wall. ^ EFFECT: possibility of well bottom zone treatment within wide frequency range with the use of sucker-rod pump jet energy. ^ 1 dwg |
