Claims (1)

Способ эксплуатации нефтегазовых скважин, включающий подогрев газлифтного газа и его подачу в затрубное пространство с температурой и расходом, определяемыми в результате решения системы двух дифференциальных уравнений тепловых балансов для нисходящего потока газлифтного газа в затрубном пространстве и восходящего потока продукции скважины в колонне лифтовых труб при условии равенства температур восходящего потока нефти и газлифтного газа в месте его перепуска в колонну лифтовых труб на глубине, большей глубины выпадения парафина из продукции скважины, отличающийся тем, что продукцию скважины подогревают в устьевом подогревателе и направляют в шлейф, в качестве газлифтного газа и топливного газа для подогрева газлифтного газа и продукции скважины используют газ высокого давления, подаваемый от установки комплексной подготовки газа, а при определении температуры подогрева и расхода газлифтного газа дополнительно задают граничное условие, при котором температура продукции скважины на входе в устьевой подогреватель была бы не менее температуры выпадения парафина из продукции скважины.A method of operating oil and gas wells, including heating gas lift gas and its supply into the annulus with temperature and flow rate, determined by solving a system of two differential equations of heat balances for the downward flow of gas lift gas in the annulus and the upward flow of production in the pipe string, provided that temperatures of the upward flow of oil and gas-lift gas at the point of its passage into the lift pipe string at a depth greater than the depth of paraffin deposition from well products, characterized in that the well products are heated in the wellhead heater and sent to the plume, high pressure gas supplied from the complex gas treatment unit is used as gas-lift gas and fuel gas for heating gas-lift gas and well products, and when determining the heating temperature and gas-lift gas flow rate additionally set the boundary condition under which the temperature of the well production at the entrance to the wellhead heater would be not less than the temperature of the paraffin and out of the well production.
