According to the medium-high frequency heating cable, the supporting steel core and the outer spiral steel layer are made of steels with good eddy current effect, resonance is formed by an inductor of the cable and serially-connected capacitors, reactance is minimum and current is maximum during resonance, heating efficiency is highest, an oil well can be rapidly heated, and electric energy sources can be effectively saved, and proved by actual tests, the medium-high frequency heating cable has an energy-saving effect of reaching up to 40-60 percent.
Description
Technical field
The present invention relates to the oil recovery heating and the signal acquiring system of oil well, specifically, relate to a kind of medium-high frequency heating cable.
Background technology
The heavy oil reserves of China is abundant, but the viscous crude viscosity is high, spend the height and content of wax height with fixed attention, and this gives exploitation and collects the defeated huge difficulty of having brought.Thickened oil recovery is main with heating exploitations such as steam soak, steam flooding, combustion in situ, hot water flooding, electric heating; What application was maximum at present is that the hollow rod electrical heating method is recovered the oil; Shortcomings such as but sucker rod has the kelvin effect weak effect, and the efficiency of heating surface is low, and be easy to cause three-phase imbalance.
Practical summary of the invention
The technical problem that the present invention will solve provides a kind of medium-high frequency heating cable, has realized the heating and the signal of viscous crude are transmitted double action.
The present invention adopts following technological means to realize goal of the invention:
A kind of medium-high frequency heating cable; It is characterized in that: comprise and support steel core and outer field spiral steel layer; Said support steel core and spiral steel layer constitute resonant tank; Said spiral steel layer comprises at least two independent connections, and the skin of said spiral steel layer is provided with insulating barrier, is provided with insulating interlayer between said support steel core and the spiral steel layer.
As the further qualification to the present technique scheme, said spiral steel layer is one group of conductor wire that is spirally coiled on the said support steel core, and the coiling density of said conductor wire can be adjusted according to the inductance value of demand.
As the further qualification to the present technique scheme, said support steel core passes through the short short circuit with outer helical layer steel layer one end, constitutes current circuit, connects power supply behind the other end serial connection electric capacity.
Compared with prior art, advantage of the present invention and good effect are: the present invention adopts the good steel of venturi effect as supporting steel core and outer helical layer steel layer, and cable end support steel core and conductor wire terminate to together in the shaft bottom; Form resonance through the inductance of cable and the electric capacity of serial connection, reactance minimum during resonance, electric current is maximum; This moment, heating efficiency was the highest, can be fast to the oil well heating, and effective saves energy source; Through actual test, energy-saving effect is up to 40%-60%; Built-in at least two connections of cable; Connection is transferred to the shaft bottom with cable along sucker rod; The terminal temperature and pressure transducer that connects in the shaft bottom of connection, can be in real time the pressure and temperature at the bottom of the measuring well accurately, saved the trouble of regularly transferring detection streamer detection downhole parameters toward the shaft bottom.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Fig. 2 is a preferred embodiment of the present invention section structure sketch map.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is made detailed description further.
Referring to Fig. 1, Fig. 2; The present invention includes and support steel core 1, spiral steel layer 2, connection 3, insulating barrier 4, insulating interlayer 5; Supporting steel core 1 skin is spiral steel layer 2, and said support steel core 1 constitutes resonant tank with outer helical layer steel layer 2, and said outer helical layer steel layer 2 comprises at least two independent connections 3; The skin of said spiral steel layer 2 is provided with insulating barrier 4, is provided with insulating interlayer 5 between said support steel core 1 and the spiral steel layer 2.
Said spiral steel layer 2 is one group of conductor wire that is spirally coiled on the said support steel core 1, and the coiling density of said conductor wire can be adjusted according to the inductance value of demand.
Said support steel core 1 passes through the short short circuit with spiral steel layer 2 one end, constitutes current circuit, connects power supply behind the other end serial connection electric capacity.
The present invention adopts the steel big, that the eddy current ability is strong of generating heat as supporting steel core 1 and spiral steel layer 2; The venturi effect of whole piece cable is very good; Heating efficiency is very high; The connections 3 that two independent insulation are arranged in the cable, the good copper of material selection communication efficiency of connection 3, connection are used for the temperature and pressure at the bottom of the measuring well.The spiral steel layer 2 of cable is done curl, and being coiled in of spiral supported on the steel core 1, has resistant to elevated temperatures insulating material to insulate between the conductor wire of support steel core 1 and spiral steel layer 2; Cable itself is exactly a big inductance like this, and the density of control spiral can be controlled inductance value, and cable is transferred to the shaft bottom through sucker rod; Through short, the end of cable support steel core 1 is shorted to together with conductor wire in the shaft bottom, forms resonance through the inductance of cable and the electric capacity of series connection; Reactance is minimum during resonance; Electric current is maximum, and at this moment heating efficiency is the highest, can heat to oil well fast like this; And saves energy source effectively, through calculate learn adopt this cable after energy-saving effect up to 40% to 60%.Built-in two connections of cable; Connection is transferred to the shaft bottom with cable along the sucker rod internal diameter; The terminal temperature and pressure transducer that connects in the shaft bottom of connection; This can be in real time the pressure and temperature at the bottom of the measuring well accurately, saved and regularly transferred the trouble that detection streamer detects downhole parameters toward the shaft bottom.
Certainly, above-mentioned explanation is not a limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also belong to protection scope of the present invention.
