Crude oil out of closing and circulating heating tube has the function of avoiding wax and reducing viscosity. The utility model has the advantages of simple structure, convenient management, great saving of energy and reduction of consumption, decrease of resistance and increase of yield, is suitable for mining of avoiding wax and reducing viscosity without crude oil of heating source, and can also be applied extensively in heat transforming field of vacuum tube of solar energy and other heat source.
Description
The utility model be a kind of oil well from thermal source superconduction wax-proof viscosity reducing device, belong to vacuum tube heat transfer technology frontier.
In oil field development, sand, wax, water, thick, gas are the technical barriers of the efficient exploitation in restriction oil field.Be to solve the puzzlement of viscous crude and wax deposition, at present both at home and abroad except that the paraffin control with inhibitor viscosity reducing process, conventional method is that oil well heat is washed with heating sucker rod and heated.But, all there are energy consumption height, the high and many management inconvenience of material consumption no matter take above-mentioned which kind of method.Oil well heat is washed the water-sensitive reflection that also often causes the stratum, influences the normal exploitation in oil field, needs the wax-proof viscosity reducing device of a kind of low-consumption high-efficiency of exploitation badly, to solve the exploitation difficult problem in high viscosity high waxy oil field.
The purpose of this utility model is a kind of superconduction heat transfer unit (HTU) of design, the higher temperature at oil reservoir pump barrel position self is transmitted to the easy wax deposition of pit shaft position and full well section rapidly, realizes oil well from the thermal source wax-proof viscosity reducing, to reduce running cost, improve development effectiveness, start the frontier of vacuum tube heat transfer technology.
For achieving the above object, the utility model has been broken through the traditional hot clean-up well exploitation pattern in high viscosity high waxy oil field, adopt the vacuum tube super heat conduction, the higher temperature at oil reservoir pump barrel position self is transmitted to the easy wax deposition of pit shaft position and full well section rapidly, has realized utilizing oil-well self thermal source wax-proof viscosity reducing, efficiently developed purpose.
Technical solution of the present utility model is: vacuum tube (1) is tightly connected to vacuumize by the multi-stage hollow sucker rod and forms.Vacuum tube (1) bottom connects the lower contact (3) that links to each other with oil well pump, fills heat-conducting medium (2) in the pipe.Vacuum tube (1) top connects topping up air extraction connector (4), and topping up air extraction connector (4) top connects top connection (5), and each connecting portion uses " O " shape sealing ring (6) and stop-leak compound (7) to do radial seal and axial end sealing respectively.
Operating principle of the present utility model is as shown in the figure: the high-efficiency heat conduction medium (2) in the higher crude oil self heat of oil reservoir pump barrel position temperature (below 1600 meters generally greater than 70 ℃) the heating, vacuum pipe (1), be subjected to heat absorption and discharge latent heat of vaporization sealing and circulating in vacuum tube (1) to transmit heat by heat-conducting medium, be transmitted to easy paraffin-troubled well section rapidly until full pit shaft, the outer easily crude oil heat exchange of paraffin-troubled well section of quick and vacuum tube (1) realizes the purpose that wax-proof viscosity reducing, efficient low-consume recover the oil.Because heat-conducting medium (2) has distinctive physical characteristics such as cold-starting, when medium is heated phase transformation, produce high-energy physics and change, and almost under the state of no thermal resistance, finish, so heat transfer rate is fast, heat waste is little, the thermal efficiency is high.
The utility model oil well is from thermal source superconduction wax-proof viscosity reducing device and conventional oil well heat is washed and the heating sucker rod heating technique compares, and has tangible technical advantage aspect following six.
1. utilize the self heat of oil reservoir pump barrel position crude oil, vacuum tube superconduction high energy heat transfer technology can promptly reach the purpose of wax-proof viscosity reducing without any need for additional heat, and is energy-saving and cost-reducing significantly.
2. heat-conducting medium start-up temperature low (30 ℃), heat transfer rate fast (being more than thousand times of copper), heat waste is little, thermal efficiency height.
3. can replace conventional methods such as oil well heat is washed, heating sucker rod heating, reduce cost for oil production and management workload significantly, prolong pump detection period, improve rate and crude output when recovering the oil.
4. because superconduction heat transfer heat waste is little, and the well head oil outlet temperature can improve 10-20 ℃, helps reducing back pressure, improve output, and create conditions, reduce construction costs significantly for simplifying three pipe companion thermal flow processes.
5. owing to the heat conduction of single tube sealing and circulating, need only heat-conducting medium and do not reveal, can long-term non-maintaining use.
6. because the well head oil outlet temperature improves, and frictional resistance reduces, promote load and alleviate, help the economize on electricity consumption reduction.
