Description
Technical field
The utility model relates to the paraffin removal unit that uses on a kind of pumping unit of oil well, specifically a kind of omnidistance electromagnetic heater.
Technical background
For improving the oil yield efficiency of high thickness oil well, people have designed electric heater unit and electromagnetic heater etc., and it is laid on the oil pick-up tube tube wall, and the crude oil that passes through is carried out heat temperature raising, thereby reduce condensing and stopping up the raising oil yield of paraffin in the crude oil.Electric heater unit has a kind of no cable mode of heating that directly heats with oil pipe and sleeve pipe energising, and its power consumption is big, and the wax removal time is long, and use cost is higher.Electromagnetic heater is to be connected to centralizer and contactor between oil pipe and sleeve pipe, the bottom of the insulating short section on oil pipe is provided with wiring terminal and some electromagnetic heaters, by the lead that variable-frequency power sources is drawn, one tunnel serial connection wiring terminal and each electromagnetic heater, another road splicing sleeve.Like this,, form electric loop, make electromagnetic heater heat and magnetize, to realize that purpose thick and the raising oil yield is fallen in the crude oil wax removal the crude oil in the oil pipe by wiring terminal, electromagnetic heater, oil pipe, contactor and sleeve pipe.But,, then not too be fit to the installation and the use of this electromagnetic heater for the oil well of high-moisture.This be because, because the water content height of crude oil in the oil well, just form short circuit easily for the electromagnetic heater of oil reservoir bottom, cause the damage of whole electromagnetic heater, the normal oil recovery of influence produced.In addition, the general character shortcoming of these two kinds of heaters is that power consumption is excessive, uses very uneconomical.
The utility model content
The omnidistance electromagnetic heater that the purpose of this utility model just provides a kind of simple installation, energy consumption is low, efficient is high, the stability of a system is good is to realize the high and stable yields in oil field.
The utility model is achieved in that omnidistance electromagnetic heater is to be connected to centralizer and contactor between oil pipe and sleeve pipe, wiring terminal on the oil pipe connects lead, be connected to the lead that is connected with variable-frequency power sources on the sleeve pipe, institute's improvements are at least one electromagnetic generators of insulating short section top socket at oil pipe, and the lead that is connected on the lead that is connected with variable-frequency power sources and the oil pipe wiring terminal joins with the two poles of the earth of electromagnetic generator respectively.
Design key of the present utility model is that some electromagnetic generators original, that distribute in oil pipe wiring terminal bottom are all removed, and the substitute is on the insulating short section top of oil pipe electromagnetic generator is set.This just is the equal of to have added a big inductive load on an electric heater unit that relies on oil pipe and sleeve pipe not to have the cable heating.Owing to have crude oil to distribute in the insulating short section upper outside of oil pipe at all, like this, no matter the height of water content in crude oil all can not produce any adverse effect to electromagnetic generator, thereby can avoid the consequent short circuit damage of electromagnetic generator.And on this position, electromagnetic generator is set, and still be to carry out the electromagnetism heating in the overall process of producing of recovering the oil, therefore still can keep the magnetization effect of electromagnetic heater, change the flowability of crude oil, suppress the growth of wax crystalline substance, realize the purpose of wax removal.Be an inductive load owing to electromagnetic generator simultaneously, thereby can avoid not having the immediate current wave phenomenon that the cable mode of heating exists.
Advantage of the present utility model, the one, easy for installation, long service life; The 2nd, can under very little power, reach higher outlet temperature, again in conjunction with the effect of magnetic effect, can reach good wax removal effect; The 3rd, the electromagnetism that has solved the high-moisture oil well heats a difficult problem, and the reliability of heater is significantly improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, cable seal well head 1 is arranged, the extracting device of oil of being made up of oil pipe 5 and oil well pump 8 etc. is housed in sleeve pipe 6 at sleeve pipe 6 supports suitable for reading of oil well.The utility model is to be connected to some centralizers 9 between oil pipe 5 and sleeve pipe 6, and the bottom is connected to the contactor 7 as electrical connector between oil pipe and sleeve pipe.Insulating short section 12 tops at oil pipe 5 are socketed with electromagnetic generator 2.Connect lead 11 between the utmost point of electromagnetic generator 2 and oil pipe wiring terminal 10, another utmost point of electromagnetic generator 2 is connected with variable-frequency power sources 13 by lead 15; Sleeve pipe 6 is connected with variable-frequency power sources 13 by lead 14.Like this, from variable-frequency power sources 13, by electromagnetic heater 2, wiring terminal 10, oil pipe 5, contactor 7, through sleeve pipe 6, return variable-frequency power sources 13, just form the electric loop of this omnidistance electromagnetic heater, the crude oil that promotes through oil well pump 8 in the oil pipe 5 is heated and magnetizes, realize purpose thick and the raising oil yield is fallen in the crude oil wax removal.
In the installation number of the insulating short section 12 top electromagnetic generators 2 of oil pipe 5, can be provided with flexibly according to the paraffin content of crude oil in the oil well: paraffin content is lower, just can be provided with one; Paraffin content is higher, just can correspondingly increase.In a word, between the plural electromagnetic generator for being connected in series.
Because oil pipe 5 also is as a conducting element in the utility model, therefore be connected at least one joint insulation sucker rod 3 on the sucker rod 4 in oil pipe 5, with the electric conductivity of blocking-up sucker rod 4, guarantee the insulation of well head, realize safety in production.
