FIELD: hydrodynamic study of wells. SUBSTANCE: proposed method includes mounting inlet funnel, packer and jet pump and lowering this assembly into well through string; then, packer is released and radiator and receiver- transducer are lowered into well; in the course of lowering, background measurements of temperature and other physical fields are performed and drainage of stratum is carried out recording bottom-hole pressures, composition and physical parameters of fluid fed from productive stratum, as well as well production rate; productive stratum is acted on by physical fields, thus cleaning the near-well zone of productive stratum from colmatage particles and filtrate of drilling mud and cement slurry; then profile of formation fluid inflow is recorded and insert is lowered into well for recording pressure-build-up curves in under-packer space with sampler and self-contained pressure gauge and preset depression is formed in under-packer space which is maintained during definite period of time; volume of formation fluid fed from productive stratum during this period of time is measured and pressure-build-up curve is recorded. EFFECT: enhanced operational reliability; increased productivity. 2 dwg
