Abstract
The utility model provides a combined type working-frequency skin electrothermal oil pumping rod. Two power supply conducting wires, a plurality of hollow oil pumping rods, a plurality of electrothermal pipes, and a power supply device are connected to form the combined type working-frequency skin electrothermal oil pumping rod. The upper part of the combined type working-frequency skin electrothermal oil pumping rod is an integral cable type electrothermal rod, and the lower part of the combined type working-frequency skin electrothermal oil pumping rod is a separate electrothermal rod. The combined type working-frequency skin electrothermal oil pumping rod has reasonable structure, and easy installation and operation. The combined type working-frequency skin electrothermal oil pumping rod can be repeatedly extracted and applied. The combined type working-frequency skin electrothermal oil pumping rod is safe and convenient to be used. The combined type working-frequency skin electrothermal oil pumping rod is a novel electrothermal oil exploitation device.
Description
The utility model belongs in the oil recovery technique field device that from deep-well electric heating extracts oil, is a kind of combined type electrothermal oil pumping pump rod particularly.
In the exploitation of carrying out oil, especially high exploitation of coagulating the viscous crude field in order to ensure the flowability of oil, prevents that oil from condensing or stop up well casing, adopted the heating oil recovery device usually from the deep-well lifting.As existing electric heating rod formula extracting device of oil, be that electric heater and oil pumping pump rod are combined as a whole, a kind of for the separated electric bar is to be connected to form by several electrothermal tubes, another kind of is that whole cable type electro hot rod is to install a whole cable in hollow pump rod.But existing separated electric bar is by up to a hundred terminals power lead to be linked into an integrated entity, and its wire joining is various, fault easily takes place, and installs complicated.Though and whole cable type electro hot rod electric connection is few, long cable extracts difficulty from deep-well, often cause cable failure or break, and can not reuse.
The purpose of the utility model provides a kind of improved electric heating rod, overcomes its deficiency with growing of prior art of collection, realizes its novel structure, is easy to install, and can repeat to extract, and is safe and convenient to use.
The utility model is achieved in that and adopts the combined type electrothermal sucker rod.To be top be threaded onto the whole cable type electro hot rod that several hollow rods connect and compose by whole cable is connected with the separated electric bar that the bottom is interconnected to constitute by several electrothermal tubes and combines for it.Two out-put supply leads of supply unit, a cable that is connected in sucker rod top, another root and is threaded onto in the sucker rod endoporus is connected to the bottom of sucker rod and the closed-loop path that sucker rod bottom tube inwall connects and composes electricity.Because the body of rod of sucker rod is a ferromagnetic steel pipe, electric current produces strong electromagnetism alternating magnetic field by steel pipe, forms electric current collection skin heat, eddy current heat and resistance heat, converts electric energy to be heat energy, by steel pipe walls heat is passed to oil in the pipe, realize the purpose of heating oil.
The utility model has adopted fabricated structure, and it has following advantage than prior art: it is rational in infrastructure, be easy to install and operation, conduct heat fast, be heated evenly, and can repeat to extract and use, safe and convenient to use.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a syndeton diagrammatic sketch of the present utility model.
As shown in drawings, the utility model is the combined type electrothermal sucker rod that is connected to form by supply unit DY, two power leads (1,2), several hollow rod (4) and several electrothermal tube (5).Its top is to be threaded onto the whole cable type electro hot rod that several hollow rods (4) connect and compose by whole cable (2), and the bottom is the separated electric bar that is interconnected to constitute by several electrothermal tubes (5).Electrothermal tube (5) is to install power lead in hollow rod, and the two ends of lead are connected with electric connection respectively, and the lead in the interconnective while body of electrothermal tube (5) connects by electric connection.The power lead of two outputs of supply unit DY (1,2), its lead (1) is connected in the top of sucker rod, it is whole cable that lead (2) is threaded onto sucker rod endoporus middle and upper part, and power lead to the sucker rod bottom that cable connects in the bottom electrothermal tube (5) connects and composes closed circuit with sucker rod bottom tube inwall.Power lead (2) also is fixedly connected on the sucker rod top by round recessed formula helical ring (3).The utility model can be according to the degree of depth of oil well, the electric heating rod bottom be set to 1/2～3/4 of whole electric heating rod by electrothermal tube (5) the separated electric bar of forming that is connected.
Claims (3)
1, a kind of combined type power frequency collection skin electric heating rod, it comprises supply unit DY, power lead (1,2), several hollow oil pumping pump rods (4) and several electrothermal tube (5), it is characterized in that this electric heating rod is threaded onto whole cable type electro hot rod and the bottom that several hollow rods (4) connect and compose by top by whole cable and is connected to form by the separated electric bar that several electrothermal tubes (5) are interconnected to constitute, power lead (1) is connected in the bottom that sucker rod top, power lead (2) be threaded onto in the sucker rod endoporus with sucker rod and connects and composes closed circuit.
2, electric heating rod according to claim 1 is characterized in that the bottom is 1/2～3/4 of a whole electric heating rod by electrothermal tube (5) the separated electric bar of forming that is connected.
3, electric heating rod according to claim 1 is characterized in that power lead (2) is fixed in the sucker rod top by round recessed formula helical ring (3).
