FIELD: oil and gas production. ^ SUBSTANCE: during bitumen or heavy oil transportation "in-situ" the reservoir is loaded by thermal energy for reduction of bitumen or heavy oil viscosity with the following characteristics: by way of at least one inductive conductive loop bitumen or heavy oil is heated and liquefied in such a manner to provide the possibility of discharge via product pipeline; the induction of conductive loop is compensated at separate areas; inductive conductive loop and product pipeline are located in such a way in relation to each other to maximise production capacity. Note that product pipeline heating power is distributed including asymmetrically. For this purpose above the product pipeline there used is an inductor as direct current conductor and inductor or inductors as current reverse conductors. Note that there provided is the possibility to transform one and the same current rate through direct conductor and current reverse conductors. The value of current rate and current phase shift are selected such to provide the possibility of conductors connection scheme to zero point in star connection. ^ EFFECT: increase of bitumen or heavy oil underground heating efficiency without steam application. ^ 21 cl, 10 dwg |
