FIELD: oil and gas industry.
SUBSTANCE: according to the method, pumping of working medium through injection wells, extraction of oil through production wells, oil sampling, determination of optic properties of oil samples, analysis of results and preparation of recommendations regarding development of oil deposit is performed. Activities aimed at increasing the oil recovery of the deposit are carried out on the deposit. Oil samples are taken from products of production wells responding to carrying out of activities aimed at increase of oil recovery, at interval of 14-15 days. Oil is separated by means of centrifugation from water in oil samples. Photocolorimetric investigations and parametric correlation analyses are made between the change of oil light absorption factor and oil production volumes during determination of optic properties of oil samples. Correlation analysis during which values of linear Poisson correlation coefficient between the change of oil light absorption coefficient and oil production volumes are calculated for each well is made. Conclusion of involvement in development of oil deposits changed at positive value of correlation coefficient as a result of activities aimed at increasing the oil recovery and unchanged at negative value is made. Activities aimed at increasing the oil recovery in order to improve the involvement in development of oil deposits changed as a result of activities are changed.
EFFECT: increasing oil recovery of deposit.
