FIELD: cleaning of formation zone near well. SUBSTANCE: method consists in mounting of inlet funnel, packer and jet-type pump from beneath upwards. This assembly is sunk on pipe-string into well, then receiver-converter of physical fields is lowered into well together with sealing unit. Background measurements of temperature and other physical fields along shaft of well are conducted, formation drainage is performed, activity of individual seams of productive pool and composition of fluid flowing into them are evaluated. Then supply of liquid medium into jet-type pump is stopped , receiver-converter is removed from well. Later tool for ultrasound action on pool is run into well. Ultrasound action on productive pool, on non-active seams and on active seams is carried out. Hydrodynamic action on productive pool is exercised during ultrasound action on seams of productive pool. On completion of action on entire pool tool for ultrasound action is taken to surface, hydrodynamic and geophysical examinations of well are conducted with use of jet-type pump and detachable functional inserts. After it assembly with jet-type pump is brought to surface and measures for starting operation of well are conducted. EFFECT: raised reliability and productivity of pump. 3 dwg
