COMMERCIAL DEVELOPMENT AND TESTING OF HIG H-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 Russi an Federation. The history of commercial development and test of new h igh-efficiency technologies of high viscosity oil-pool known for its c omplex 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 pause s (PDHT/P), cyclic bed heat treatment (CBHT). The ground is given to t he main geological-physical criteria of formation choice to effectivel y use new technologies on. The main results of the new technologies co mmercial 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.
