Abstract:

Recently, in the oil industry, there has been a tendency towards a deterioration in the structure of oil reserves, which is manifested in the growth of hard-to-recover oil, an increase in the number of fields put into development with complicated geological and physical conditions, reservoirs with high oil viscosity, etc. The most common methods for developing high-viscosity oil fields are thermal. But they require large material costs, resulting in a significant increase in the cost of oil produced. Therefore, the improvement of existing and the creation of more efficient thermal methods is an important task in oil production. One of the highly effective fundamentally new combined methods for the development of fields of increased and high viscosity of oil in fractured-porous carbonate reservoirs is the method of thermopolymer and cold polymer exposure (RF Patent No. 860553, authors Yu. V. Zheltov, V. I. Kudinov).
