METHOD OF SYNERGISTIC ACTION ON WELL AND PRODUCTIVE POOL AND GEAR FOR SYNERGISTIC ACTION ON WELL AND PRODUCTIVE POOL Russian patent published in 2001 - IPC

FIELD: running of oil, water intake and other wells. SUBSTANCE: method and gear can be used to clean wells from deposits formed in piping strings and to treat face zone of pool. Method includes transmission of hydraulic pulses from radiators of hydraulic hammers put on well-head over tubing string via its upper butt and over column of liquid in well through its upper level on to productive pool. Molecular- wave vibrations are simultaneously transmitted in well. Pressure rises by way of supply of liquid from pump with pressure accumulator joined with inlet to tubing string to well-head. Water hammers are formed in column of liquid in well by way of periodic shut-off of pump inlet by radiators of water hammers while molecular-wave vibrations are transmitted from them to tubing string and column of liquid in well. Hydraulic hammers in column of liquid in well are formed by periodic shut-off of depression chamber mounted at well-head. Hydraulic pulses are formed simultaneously with use of radiators of low- and high-frequency vibrations under conditions of static pressure of liquid in tubing string created in advance. Gear for SYNERGISTIC action on well includes generators of impact momenta with strikers and radiators and pump. Distribution chamber is connected to internal space of well. Radiators are uniaxially mounted slide fit in distribution chamber for shut-off of discharge pipe-line of pump. One of pulse generators is low-frequency generator and the other pulse generator is high-frequency generator. Converter comes in the form of resonator-converter comprising tubular body with radial conduits. Upper part of spring-loaded plunger is made of piezoceramic material and side surfaces are capable of periodic shut-off of radial conduits in body depending on position of plunger. Distribution chamber is made up of cylindrical and confuser parts. Cylindrical part has hydraulic coupling with depression chamber and confuser part has hydraulic coupling with resonator- converter. EFFECT: raised productivity of wells thanks to enhanced penetrability of rocks. 7 cl, 1 dwg
