FIELD: hydrodynamic methods of strata investigation. SUBSTANCE: deep-seated pressure gage is lowered to bottom filled with stratum fluid. The pressure gage is used to measure pressure along well shaft followed with calculation of medium fluid density. Then the well is open and fluid level is decreased. Volume of the extracted fluid is measured. Well is discharged and pressure restoration curve is recorded. On appearing fluid in well mouth the well is closed and recording is proceeded until investigation is over. Hydrodynamic parameters of the stratum is determined on the base of the data obtained. EFFECT: reliable data obtaining. 2 dwg
