DEVICE FOR WAVE TREATMENT OF FORMATION

摘要

oil producing industry. SUBSTANCE: device has barrel with central inlet channel. Device control channel is made in the form of many intercommunicated through control channels. Inlet of control channels are connected with a nozzle. Jet ejector is connected with outlet of one of working channels. Ejector external wall and internal surface of plugged barrel in its lower part form a circular cylindrical channel. Chamber inlet is connected with outlet of the second working channel. Chamber outlet is connected with injection channel of ejector. Branch of control channel feedback is adjustable in length and volume. EFFECT: higher efficiency of formation treatment due to possible selection of working frequency of vibration and due to higher reliability, radiation power and production of pulse of any shaped. 4 dwg
