METHOD FOR INTRODUCING INDUCTOR LOOP INTO ROCK FORMATION Russian patent published in 2018 - IPC E21B36/04 E21B43/24 E21B43/30 

FIELD: oil industry.

SUBSTANCE: group of inventions relates to a method for introducing an inductor loop into a rock formation for heating an oil reservoir as well as the corresponding inductor device. Method includes drilling first inductor bore (120) for introducing first inductor arm (20) and drilling second inductor bore (130) for introducing a second inductor arm (30). At least one intersecting bore (140) is drilled create first area of intersection (150) with first inductor bore (120) and second area of intersection (150) with the second inductor bore (130). First inductor arm (20) is introduced into first inductor bore (120) and second inductor arm (30) is introduced into second inductor bore (130). At least one connecting arm (40) is introduced into intersecting bore (140) for electrically conductive connection to two inductor arms (20, 30) in two areas of intersection (150) so as to form inductor loop (90).

EFFECT: technical result is to increase the efficiency of using an induction loop in deep wells to heat the oil reservoir.
