COMMERCIAL DEVELOPMENT AND TESTING OF HIGH-EFFICIENCY TECHNOLOGIES OF HEAT-CARRIER INJECTION AT OIL-FIELDS WITH COMPLEX GEOLOGICAL CHARACTERISTICS

Presented in the paper are brief data on the Udmurt Republic oil field characteristics that is one of the oil-producing regions of the Russian Federation. The history of commercial development and test of new high-efficiency technologies of high viscosity oil-pool known for its complex geological and physical characteristics is given. The physical, hydrodynamical and technological essence of technogies are revealed: pulse-dosing heat treatment of bed (PDHT), its modification with pauses (PDHT/P), cyclic bed heat treatment (CBHT). The ground is given to the main geological-physical criteria of formation choice to effectively use new technologies on. The main results of the new technologies commercial introduction dynamics and their technological efficiency are shown on the basic project of petroleum industry - the A-4 bed of oil-pool, Bashkhir stage, Middle Carboniferous period of Gremikhinsoye oil-field in Udmurtiya.
