Claims (9)

1. Устройство депарафинизации нефтегазовых скважин, содержащее спускаемый в зону возможного парафинообразования нагревательный кабель, содержащий по меньшей мере два нагревательных элемента, и соединенную с ним систему управления его нагревом, отличающееся тем, что нагревательный кабель имеет по всей длине металлический или пластмассовый полый гидравлический канал, подключенный в верхней части к дозировочному насосу и емкости с химическим реагентом, а нижняя часть открыта и соединена со скважинной жидкостью, причем внутренний диаметр гидравлического канала составляет 10÷50% от диаметра кабеля.1. A device for dewaxing oil and gas wells, containing a heating cable lowered into a zone of possible paraffin formation, containing at least two heating elements, and a heating control system connected thereto, characterized in that the heating cable has a metal or plastic hollow hydraulic channel along the entire length, connected in the upper part to the metering pump and a container with a chemical reagent, and the lower part is open and connected to the borehole fluid, the inner diameter p of the hydraulic channel is 10 ÷ 50% of the cable diameter. 2. Устройство по п.1, отличающееся тем, что на верхней и нижней частях гидравлического канала могут быть установлены клапаны обратного давления или управляемые клапаны/вентили.2. The device according to claim 1, characterized in that on the upper and lower parts of the hydraulic channel can be installed back pressure valves or controlled valves / valves. 3. Устройство по п.1, отличающееся тем, что в кабеле могут быть установлены только нагревательные элементы или кабель может содержать только гидравлический канал.3. The device according to claim 1, characterized in that only heating elements can be installed in the cable or the cable can contain only a hydraulic channel. 4. Устройство по п.1, отличающееся тем, что кабель может содержать дополнительные сигнальные проводники для подключения датчиков температуры и/или давления.4. The device according to claim 1, characterized in that the cable may contain additional signal conductors for connecting temperature and / or pressure sensors. 5. Устройство по п.1, отличающееся тем, что кабель может содержать несколько гидравлических каналов различного диаметра.5. The device according to claim 1, characterized in that the cable may contain several hydraulic channels of various diameters. 6. Способ депарафинизации нефтегазовых скважин, включающий спуск в насосно-компрессорную трубу нагревательного кабеля с нагревательными элементами, подключение нагревательных элементов кабеля к регулируемому источнику электропитания, выделение нагревательными элементами тепловой мощности по длине кабеля, отличающийся тем, что находящийся в кабеле гидравлический канал подключают к дозировочному насосу и осуществляют подачу химического реагента по гидравлическому каналу в скважину ниже точки начала кристаллизации парафиногидратов, а в качестве химического реагента применяют растворители, ингибиторы, деэмульгаторы, депрессаторы, модификаторы.6. The method of dewaxing oil and gas wells, including the descent into the tubing of the heating cable with heating elements, connecting the heating elements of the cable to an adjustable power source, the heating elements emitting thermal power along the length of the cable, characterized in that the hydraulic channel in the cable is connected to the metering pump and carry out the supply of a chemical reagent through a hydraulic channel into the well below the point of crystallization of paraffin hydrate And as a chemical reagent used solvents, inhibitors, demulsifiers, depressant modifiers. 7. Способ по п.6, отличающийся тем, что подачу химического реагента и подачу тепловой мощности осуществляют раздельно, независимо друг от друга.7. The method according to claim 6, characterized in that the supply of the chemical reagent and the supply of thermal power are carried out separately, independently of each other. 8. Способ по п.6, отличающийся тем, что подачу химического реагента и/или тепловой мощности производят циклически.8. The method according to claim 6, characterized in that the supply of the chemical reagent and / or thermal power is performed cyclically. 9. Способ по п.6, отличающийся тем, что подачу химического реагента осуществляют без дозировочного насоса самотеком за счет гидростатического давления.9. The method according to claim 6, characterized in that the supply of the chemical reagent is carried out without a metering pump by gravity due to hydrostatic pressure.
