RESULTS OF GEOPHYSICAL MONITORING OF THE DEVELOPMENT OF THE HORIZON PK-2 OF THE PODKIRMAKINSKY SUITE OF THE NEFT DASHLARY FIELD

Abstract

The article is devoted to the study of the current state of development of the second horizon of the Podkirmakinsky suite (PK-2) of the Productive stratum (PS) of the Neft Dashlary field, which has been in operation for more than 60 years. The results of the study by the method of complex areal interpretation of geophysical survey data of wells and geological and field information are presented. Three-dimensional geo models, built on the basis of petrophysical parameters obtained after the interpretation of geophysical and geological data using the DV Seys Geo program are given in the article. The results of the analysis of the state of water impact are presented, the values of the oil saturation factor during well drilling are summarized, the values of the current oil saturation factor are calculated taking into account the extraction of oil, the results of studying the nature of saturation of reservoirs in the context of production wells by the method of pulsed neutron logging (PNL), as well as a comparative analysis of these values along the horizon PK-2 of the PS of the Neft Dashlary field.
