PROCESS OF ACTION ON FACE ZONE OF POOL AND GEAR FOR ITS IMPLEMENTATION

摘要

industrial exploitation and restoration of productivity of wells under complicated conditions of development. SUBSTANCE: process of action on face zone of pool includes vibration-wave action and simultaneous periodic reduction of pressure on face below seam pressure. Vibration-depression action is implemented in turn on each perforation conduit or group of perforation conduits with local excitation of elastic vibrations right in them and with local reduction of pressure below seam pressure across inlet and inside perforation conduits. Gear for implementation of process includes lowered hollow body and cylindrical flow chambers hydraulically coupled to it. Each chamber is fitted with swirler of liquid flow, pressure nozzle, outlet toroidal chamber with outlet nozzle. EFFECT: increased efficiency of cleaning of face zones of pool. 9 cl, 2 dwg
