Abstract
The utility model relates to a device for removing wax used in the field of oilfield oil recovery, and particularly discloses an electromagnetic heating device for removing and preventing wax. An oil inlet of an IF (Intermediate Frequency) electromagnetic heater is communicated with an oil outlet pipe of an oil well, and an oil outlet of the IF electromagnetic heater is connected with a three-way pipe fitting, wherein one connector of the three-way pipe fitting is communicated with a ring space via a production tree, and the other connector of the three-way pipe fitting is connected with an oil delivery pipe. By adopting the device provided by the utility model, after being heated by the IF electromagnetic heater, the temperature of the crude oil in the delivery pipe is higher than precipitation temperature of wax, so that the precipitation of wax crystals is reduced and prevented for keeping the oil delivery to be sustained and smooth; and the heated crude oil is reinjected into the ring space, so that the frequency for well cleanup is greatly decreased, and the cost for well cleanup is reduced without affecting the oil layer.
Description
Technical field:
The utility model relates to the used paraffin removal unit of oil recovery field, oil field oil well, especially electromagnetism heating wax removal wax-proofing apparatus.
Background technology:
China's oil field waxy crude oil output is bigger, waxy crude oil is a kind of mixed phase hydrocarbon mixture, in the Crude Oil Transportation process, when the waxy crude oil temperature is lower than the FCTA temprature of wax, the brilliant particulate of wax just begins to separate out in oil stream and on tube inner wall and the sucker rod, Crude viscosity sharply increases, constantly reduce with temperature, the quantity of separating out the wax crystalline substance increases, and is cross-linked with each other and reticulates structure, after net structure reaches certain intensity, crude oil will lose mobile and condense, this just has a strong impact on the production and the conveying of crude oil, must stop production to carry out could continuing oil transportation after the heavy artificial de-waxing block clearing, has influenced crude oil production progress and the application life that has shortened oil pipe greatly.
Summary of the invention:
The purpose of this utility model is to address the above problem, and the not electromagnetism of wax deposition heating wax removal wax-proofing apparatus is provided in a kind of simple in structure, oil pipe oil transportation process.
The technical solution of the utility model is:
Intermediate frequency electromagnetism heating paraffin removal unit, the oil-in of intermediate frequency electromagnetic heater is communicated with the flowline of oil well, the oil-out of intermediate frequency electromagnetic heater connects tee pipe fitting, and an interface of tee pipe fitting is through the ring set space of production tree connection oil well, and the another one interface of tee pipe fitting connects petroleum pipeline.
Concrete, the pipeline that the oil-out of tee pipe fitting and production tree are communicated with is provided with valve and flow meter.
Concrete, the intermediate frequency electromagnetic heater is made of pipeline, insulated thermal insulating layer, magnetic conduction coil layer, and pipeline external surface is provided with one deck insulated thermal insulating layer, and insulated thermal insulating layer is provided with one deck magnetic conduction coil layer outward, the magnetic conduction coil layer links to each other with power supply, and the magnetic conduction coil layer is coiled to form by electromagnetic wire.
Concrete, the intermediate frequency electromagnetic heater also comprises control circuit, and electromagnetic wire links to each other with power supply by control circuit, and control circuit comprises a frequency changer circuit at least.
The beneficial effects of the utility model are, after the heating of intermediate frequency electromagnetic heater, the temperature of crude oil is higher than the temperature of separating out of wax to the utility model with the crude oil in the oil pipe, thereby reduce and prevent separating out of wax crystalline substance, and it is unimpeded to keep petroleum pipeline to continue; With the heating after the crude oil re-injection go in the ring set space, greatly reduce the well-flushing number of times, reduced the well-flushing expense, and to oil reservoir without any influence.The utility model is simple in structure, durable in use, and is safe and reliable, and strong adverse circumstances adaptive capacity is arranged.
The electric current that changes flows through the magnetic field that the magnetic conduction coil can produce the high speed variation at a high speed, when just can producing countless little eddy current during by the magnetic conductive metal body, the interior magnetic line of force in the magnetic field makes atomic disorder strong collision in the metallic object, heating at a high speed voluntarily, thus realize the quick conversion of electric energy to heat energy.
