Abstract

The share of hard-to-recover oil reserves according to the estimates of the Ministry of Energy of the Russian Federation currently exceeds 67%, while 13% are classified as high-viscosity oil. The absolute value of such reserves according to various estimates will increase to 5-7 billion tons, which determines the relevance of the tasks aimed at improving the efficiency of the development of fields with highly viscous oil for the future for more than 50 years. For the development of such reserves, it is necessary to differentiate the use of known and new development methods based on the structuring of the petrophysical and filtration properties of productive strata and the physicochemical properties of fluids saturating them. The analysis of the distribution of porosity, permeability of the Tournaisian and Bashkir longlines, Verey, Kashira, Tula horizons, as well as the viscosity of the oil saturating them and, related to this, such parameters of the productive layers as mobility, hydraulic conductivity and finally displacement factor, revealed three groups of productive layers with different values of the sensitivity of the change in the coefficient of displacement from the coefficient of mobility, which must be taken into account when planning and justifying geological technology eskih activities formation or development of a system modification. This is especially important for small fields of high-viscosity oil, which are characteristic of the Western slope of the South Tatar arch (LC YTS).

    Key words:

    viscous oil; oil displacement; correlation coefficient; oil mobility; permeability
