The high intermediate frequency electric heating device comprises a well mouth distribution box and a heating body, wherein the heating body is a superconductor, a heat insulating layer wraps the outer surface of the heating body, and an inductive coil winds the heat insulating layer and is provided with a heat sensor; a central processing module, a temperature signal collection module and a power supply circuit module all of which are connected are fixed in the well mouth distribution box; the inductive coil is connected with the power supply circuit module, and the heat sensor is connected with the temperature signal collection module. By means of the high intermediate frequency electric heating device, the temperature of the crude oil flowing through the well mouth rises, the crude oil is prevented from congealing at the well mouth, and the problems that outward transportation of the crude oil is difficult and wells are clamped are solved effectively.
Description
Technical field
The utility model relates to and well head is flow through the high intermediate frequency electric heater unit that crude oil heats in recover the oil producing.
Background technology
Paraffin easily was condensed on the oil transportation well head pipeline when high waxy oil well was recovered the oil production, and blocking pipe hinders crude oil flow, and it is high to cause loopback to press, outer defeated difficulty; During the heavy oil wells exploitation, crude oil easily condenses in the pit shaft, and pumping unit load increases, and motor idle running causes holddown normally to produce when serious, causes the crude oil exporting difficulty.
The utility model content:
In order to solve crude oil easily at the well head outer defeated hard problem that condenses, the utility model provides a kind of high intermediate frequency electric heater unit.
The technical solution of the utility model is: a kind of high intermediate frequency electric heater unit, comprise well head switchbox and calandria, and described calandria is that the superconductor appearance has been tied up isolation layer, isolation layer twines inductance coil outward, is equipped with heat sensor on the above-mentioned inductance coil; Fixing interconnective central processing module, temperature signal collection module and power supply circuits module in the above-mentioned well head switchbox, above-mentioned inductance coil is connected with the power supply circuits module, and heat sensor is connected with the temperature signal collection module.
Above-mentioned calandria is fixed in the housing, and forms ring cavity with housing, and the two ends of housing connect respectively crude oil import and outlet, and import and outlet are communicated with ring cavity.
Above-mentioned inner walls is lined with insulation layer.
The beneficial effects of the utility model are: owing to be provided with above-mentioned high intermediate frequency electric heater unit at outer wellhead output oil passage, utilize the calandria in this device that the crude oil of flowing through is heated, thereby the crude oil of realizing the well head place heats up rapidly, simultaneously automatic monitoring well logging mouthful crude oil temperature solves production trunk line reduction loopback and presses high problem; By circulation well cleanup in the deep fat backflow well, prevent the viscous crude holddown that condenses, effectively solve outer defeated hard problem.And this electric heater unit heat energy loss is little, and capacity usage ratio is more than 90%, and crude oil heats up rapidly, and temperature rises 50 ℃ in the 0.5min.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Figure 1 and Figure 2, this high intermediate frequency electric heater unit, comprise well head switchbox 1 and calandria, described calandria is that superconductor 4 appearances have been tied up isolation layer 3, isolation layer 3 outer winding inductance coils 2, and the effect of isolation layer 3 is to prevent that Temperature Distribution is too fast, burn coil, be equipped with heat sensor 7 on the above-mentioned inductance coil 2, calandria is responsible for gathering the well head crude oil temperature, and crude oil is heated; Above-mentioned well head switchbox 1 fixing interconnective central processing module, temperature signal collection module and power supply circuits module, above-mentioned inductance coil 2 is connected with the power supply circuits module, heat sensor 7 is connected with the temperature signal collection module, start and stop by central processing unit control calandria, make well head excessively oil remain in the stationary temperature scope, as shown in Figure 2.
Above-mentioned calandria is supported and fixed in the housing 6, and forms ring cavities 10 with housing 6, and the two ends of housing 6 connect respectively crude oil import 8 and export 9, and import 8 and export 9 and be communicated with ring cavity 10.
In addition, above-mentioned housing 6 inwalls are lined with insulation layer 5, run off to reduce heat.
The operating principle of this high intermediate frequency electric heater unit: the high medium frequency alternating current that at first industrial-frequency alternating current is converted to 1～100KHZ, utilize electromagnetic induction principle, convert electric energy to the alternating magnetic field of same frequency by inductance coil, and utilize eddy current effect, resistance heating by metal itself converts electrical energy into heat energy.Simultaneously by the hysteresis effect characteristic object is heated up rapidly, enter the crude oil of this heater from import 8, after above-mentioned calandria heating, flow out from exporting 9.The instrument mode of heating is directly heating, and internally concussion makes its molecule, the vibration of atom per second, rubs more than one hundred million times more than, and this mode of heating has been cancelled the energy transmission link, and loss is extremely low, and capacity usage ratio is more than 90%, and heat time heating time is short.During work, the temperature signal of the high-frequency generator that is connected with central processing module by passing back on the calandria, whether reach the heating-up temperature standard by the central processing module judges Wellhead crue oil, and the start and stop by power supply circuits module controls calandria, the outlet crude oil temperature is remained in the steady temperature scope.
The oil pipeline inloop is pressed high well head, and the content of wax is high, directly enters after the heating crude oil in the main line, and the wax stone that adheres on the dissolving tube wall increases area of passage, reduces the crude oil flow resistance, presses high problem thereby solve loopback.
Viscous crude is easily coagulated the well that blocks, regularly will heat thick crude oil and enter in the oil jacket annular space, again through oil pipe backflow well head, reduce Crude viscosity, prevent that viscous crude is set in tube wall and avoids the holddown phenomenon to occur.
