Abstract

FIELD: oil industry. SUBSTANCE: accurate determination of degree of initial oil saturation in gas cap 5 is performed by drilling pressure holes 1 and pilot holes 2, 3. By pumping one or several displacing agents such as water into stratum, fragment of oil boundary is forced into gas cap 5. Determined in pilot holes 2, 3 is time of appearing oil front 6 and front of accompanying fluids (water) 7. Dimensions of oil boundary fragments are also defined. Initial saturation in gas cap 5 is determined according to data relating to parameters of oil boundary before displacement into gas cap 5 and according to period of time of appearing fluid fronts to pilot holes 2, 3. Holes can be arranged according to flat-parallel or flat-radial displacement of oil boundary fragment. EFFECT: high efficiency. 1 dwg
