Abstract
The AC oil pipe heater with low power consumption consists of polished rod, insulating oil pumping rod, insulating short piece, insulating centralizer, pumping rod, oil pipe, pump barrel, compensator, contactor, casing, pipe string, cable, transformer, sensor, electric control box, etc. It is powered by 380 V power supply with transformer in the same box as the control circuit, and inside the electric control box, there are also power failure protecting system, I/O current and voltage indicator, and well liquid temperature display. The upper part over the polished rod is not charged, and this results in saving in power and safety in well head. The integrated transformer and the distribution cabinet lead to simple structure and convenient operation.
Description
Affiliated field
The present invention relates to the downhole tool that uses on a kind of field produces, particularly a kind of low power consuming alternating current oil pipe electric heater unit.
Background technology
Coagulate problem oily, that viscous crude solves viscosity reduction for the oil well height at present, adopt direct current oil pipe electric-heating technology, this technology is often charged owing to well head, and oil pipe is had corrosiveness, and it is big to produce power consumption, and poor stability makes troubles to oil field production.
Summary of the invention
The invention provides a kind of low power consuming alternating current oil pipe electric heater unit, it can reduce electric quantity consumption greatly, improves safety, with power be the dry-type transformer of 100KW molten with power distribution cabinet be one, thereby formed new easy to operately, product can be widelyd popularize in economic and practical oil field.
The object of the present invention is achieved like this, it is by polished rod (1), insulation sucker rod (2), insulating short section (3), insulation centralizer (4), sucker rod (5), oil pipe (6), pump barrel (7), expansion loop (8), contactor (9), sleeve pipe (10), pipe string (11), cable (12), transformer (13), terminal plate (14), well head (15), sensor (16), electric control box (17) is formed, well head (15) is connected set pipe (10) down, in sleeve pipe (10), be connected to polished rod (1) from the top down according to this, insulation sucker rod (2), insulating short section (3), insulation centralizer (4), sucker rod (5), oil pipe (6), pump barrel (7), expansion loop (8), contactor (9), sleeve pipe (10), pipe string (11), cable (12) one ends are connected with insulating short section (3), the other end is connected with electric control box (17) by well head (15), sensor (16) one ends are connected with well head, the other end is connected with electric control box (17), transformer (13) is connected one with electric control box (17), and electric control box (17) one ends are connected with terminal plate (14).
The present invention utilizes the alternating current principle, and as conductor, sleeve pipe makes oil pipe produce heat energy as the loop, thereby reaches the purpose of oil pipe heating with oil pipe.To be that the dry-type transformer of 100KW and power distribution cabinet are molten with power be one to this technology, easy to operate, economic and practical.
The present invention is owing to adopted insulation sucker rod, insulating short section, insulation centralizer and cable one end directly to be connected with insulating short section, the other end is connected with electric control box by well head, make more than the polished rod all not charged, saved electric energy, improved the safety of well head, transformer and power distribution cabinet are molten to be one, constructing operation is convenient, it is simple in structure, and is reasonable in design, is well suited for field popularization application.
Description of drawings
Accompanying drawing is the structural representation of invention.
The present invention is further described below in conjunction with accompanying drawing.
As shown in the figure; by polished rod 1; insulation sucker rod 2; insulating short section 3; insulation centralizer 4; sucker rod 5; oil pipe 6; pump barrel 7; expansion loop 8; contactor 9; sleeve pipe 10; pipe string 11; cable 12; transformer 13; terminal plate 14; well head 15; sensor 16; electric control box 17 is formed; with the power supply of adjustable dry type 380V transformer 13 as used power supply; it is 100KW that 380V voltage is introduced the dry type power-adjustable; voltage is by 23V; 63V; 105V; 155V; 210V; 260V; 310V; 340V and 370V9 adjustable special transformer; adjustable transformer 13 and control circuit are in an electric control box 17, and electric control box 17 also is provided with circuit breaking protective system output current voltage input and current voltage and shows the down-hole liquid temperature display system.
The temperature required certain voltage of being transferred to of oil well is introduced under first oil pipe through the electric pump well head, make the following electrical heat energy that produces of second oil pipe, for preventing first oil pipe and first charged well head that returns of sucker rod, on connect glass fibre reinforced plastic insulating pipe nipple 3, second following generation electric current with voltage of oil pipe forms power makes oil pipe produce heat energy, heat penetration is lowered to desired depth then by oil jacket contactor 9 according to the production characteristics requirement of producing well, returns ground from sleeve pipe 10 ground connection.
Mainly solve oil well paraffinication, viscosity reduction, raising crude exports temperature.
Its applicable cases is compared with the heating of hollow stem cable and is economized on electricity 2/3, and the well head outlet temperature is identical, and it is easy that the down-hole does not have cable heating operation technique in addition, and once investment is lower.
