THE EFFECTIVENESS OF THE USE OF VISCOELASTIC SYSTEMS ON THE EXAMPLE OF AN OIL FIELD IN THE UDMURT REPUBLIC

 

Annotation. This article discusses ways to increase oil recovery by using viscoelastic systems. Such systems have selective penetration into the water-saturated part of the productive reservoir, and with the help of these systems, it is possible to create a sealing ring behind the casing, which can eliminate the problem of inter-column pressures in the cased trunk. To identify the localization of residual reserves and the selection of candidate wells to justify the selected VUS, a sector geological, and then a hydrodynamic model was built. As part of the construction of a volumetric sector geological model for productive sediments, a correlation of the section was carried out, markers were identified, and intervals of productive strata were determined. As the initial information for the construction of the model, data from the reinterpretation of the materials of geophysical well surveys (GIS) were used. The contact of clay deposits with carbonates of the Bashkir horizon was used as reference boundaries. The layers were correlated by dense bundles of limestone, reflected by the maximum values on the NGC. In accordance with the performed correlation, the structural surfaces of productive deposits were constructed. The technological efficiency of the use of the VUS based on the calculated development indicators is also revealed.

Key words: viscoelastic composition, polymer, hydrodynamic model, oil, field, oil recovery.
