The utility model adopts the technical scheme that the equipment mainly comprises a variable frequency power supply, a flange-type insulation hanger, a communicating pipe, a sleeve, an oil pipe, a contactor, a secondary cable and a plurality of groups of insulation centralizers, wherein the oil pipe is fixed in the middle of the sleeve through the insulation centralizers, the top end of the sleeve is connected with the flange-type insulation hanger through the communicating pipe, the oil pipe is fixed at the bottom of the sleeve through the contactor, the secondary cable penetrates the flange-type insulation hanger and is fixed on the outer wall of the oil pipe, and the secondary cable also penetrates the contactor and is fixed on the outer wall of the sleeve, and the variable frequency power supply is switched in. The utility model has the benefits that the electrical heat energy supplied by an underground oil pipe joint is used for compensating the heat loss of the raw oil during the uplifting process, thereby increasing the raw oil temperature and the temperature of the oil pipe wall to achieve viscosity reduction or the melting of paraffin deposit on the pipe wall, reducing the phenomenon of hindering, blocking and clamping of a pipe line, and achieving the purposes of energy conservation, production protection and increase.
Description
One, technical field:
The utility model relates to a kind of variable-frequency electromagnetic oil pipe heating oil extraction equipment, particularly a kind of high content of wax, high condensation point, high bitum three high oil well variable-frequency electromagnetic oil pipe heating oil extraction devices.
Two, background technology:
Be richly stored with viscous crude, height of China coagulates oily resource, viscous crude, high its main feature of oil of coagulating have three height, that is: the high content of wax, high condensation point, high asphalitine, three high oil viscosities are big, mobile poor, this quasi-oil is when rising and cool off, can on tubing wall, produce strong deposition, must take certain measure to reduce its viscosity during exploitation.At present, the technology of application comprises utilizes heater element heating, mixes hot water, mixes method such as deep fat heating; Mix hot water, to mix the deep fat process heat loss of energy big, the technological process complexity, management workload is big, the operating cost height; Heater element heating in the U.S. based on the heat tape heating technique, in Russia based on the AC coil heating technique, in China based on hollow rod single phase ac electric-heating technology.Problems such as there are complex process in the heat tape heating technique of the U.S. and the heating technique of Russian AC coil, investment is high, the heat effect is low, maintenance difficult.And the hollow rod electric-heating technology of China is owing to adopt the single phase poaer supply power supply also to have a lot of problems: the too much use as single phase poaer supply causes the three-phase power distribution system imbalance, neutral point seriously is offset, loss strengthens, the fault rate height, bigger etc. to electrical network harm, simultaneously, hollow stem electric tracing technology must be equipped with hollow stem and down-hole high-temperature cable, and cost height, electric conversion efficiency are low, poor reliability, accident rate height.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of three high oil well variable-frequency electromagnetic oil pipe heating oil extraction devices are provided.
Its technical scheme is: mainly be made up of variable-frequency power sources, flange form insulation hanger, communicating pipe, sleeve pipe, oil pipe, contactor, secondary cable, insulation centralizer, oil pipe is fixed on the centre of sleeve pipe by many groups of insulation centralizers, the top of sleeve pipe is by communicating pipe adpting flange formula insulation hanger, the bottom of sleeve pipe is by the fixing oil pipe of contactor, secondary cable passes flange form insulation hanger, be fixed on oil-pipe external wall, pass contactor, be fixed on sleeve outer wall, insert variable-frequency power sources.
The beneficial effects of the utility model are: provide electrical heat energy to the downhole oil manifold, compensate crude oil at the last thermal loss of lifting in the way, the tube wall temperature that improves crude oil temperature and oil pipe reaches and falls thick viscosity reduction or fusing wall wax deposition, reduce the phenomenon that block appears in pipeline, exempt mix thin oil, with other viscosity reducing technologies such as thinners, reduce the oil pumper load, reach energy-conservation guarantor's product and volume increase purpose.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: flange form insulation hanger 1, communicating pipe 2, sleeve pipe 3, oil pipe 4, contactor 5, secondary cable 6, insulation centralizer 7.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model mainly is made up of flange form insulation hanger 1, variable-frequency power sources, communicating pipe 2, sleeve pipe 3, oil pipe 4, contactor 5, secondary cable 6, insulation centralizer 7, oil pipe 4 is fixed on the centre of sleeve pipe 3 by many groups of insulation centralizers 7, the top of sleeve pipe 3 is by communicating pipes 2 adpting flange formula insulation hanger 1, fixedly oil pipe 4 of contactor 5 is passed through in the bottom of sleeve pipe 3, secondary cable 6 passes flange form insulation hanger 1, be fixed on oil pipe 4 outer walls, pass contactor 5, be fixed on sleeve pipe 3 outer walls, insert variable-frequency power sources.
Variable-frequency power sources is with the three-phase main-frequency alternating current of the secondary output of extraordinary isolating transformer, after frequency-conversion processing by being connected to the secondary cable of flange form insulation hanger, when electric current during by oil pipe and borehole wall sleeve pipe, generate heat because of having certain resistance, square being directly proportional of the heat that produces and electric current, the frequency conversion electric current converts heat energy to the thermal resistance effect form on oil pipe, be used to offset the stratum heat waste or supply with crude oil, falls thick, wax removal drag reduction to reach a high temperature, guarantees the purpose that pipeline is unimpeded; For preventing short circuit midway, high-strength high temperature-resistant tubing coupling insulation centralizer is housed in tubing coupling.
Flange form insulation hanger has the oil pipe of suspension, rigidity sealing, explosion-proof conducting triple functions, plays crucial effects in system.
