FIELD: well logging, specifically, by methods of neutron-neutron and hydrodynamic logging for enhancement of operational investigations of collectors of oil and gas in wells complicated by zones of penetration of flushing fluid. SUBSTANCE: investigated medium is irradiated by pulse flux of fast neutrons, fluxes of thermal and epithermal neutrons in the form of curves of time dip are measured after pulses of neutrons in process of forced deformation of penetration zone in local sealed section of pool. With this in mind non-stationary fluxes of thermal or epithermal neutrons or of both of them are measured as well as pressures in process of uninterrupted or cyclical hydrodynamic action on pool by causing inflow of fluid from pool without its seal failure. EFFECT: improved efficiency and reliability of process. 4 dwgr
