Abstract
A heating furnace with double coil pipes comprises a chimney (1), a furnace body (2), an external coil pipe (3), an internal coil pipe (4) and a pedestal (5). The heating furnace with the double coil pipes is characterized in that the furnace body (2) is formed via overlap of a cylinder and a cone; the top of the furnace body (2) is provided with the chimney (1); the internal cavity of the pedestal (5) is a hearth; and the spring-shaped external coil pipe (3) and the internal coil pipe (4) are sleeved together and both arranged in the furnace body (2). The heating furnace with double coil pipes has novel structure, convenient installation, high heat efficiency and long service life; liquid produced by an oil well and mixed water can be heated at the same time; mixed liquid temperature can be effectively increased; thickened oil viscosity, well mouth return pressure and ton liquid electricity consumption can be reduced; and a thickened oil well can be hot-washed via high temperature mixed water, so hot-washing cost can be saved.
Description
Technical field
The utility model relates to oil-field thick-oil exploitation ground heating and water-doped viscosity reduction heating furnace technology, specifically a kind of dual coil pipes heating furnace.
Background technology
Continuous reduction along with oil field high-quality recoverable reserves, the shared ratio of viscous crude is increasing, viscous crude has the features such as viscosity is high, density large, flow difficulties, enter after ground flow because temperature reduces, viscosity of crude raises rapidly, and flowage friction resistance is large, causes the load of ground oil-gas gathering and transportation system generally to increase, operational efficiency is lower, and system energy consumption is higher.The heating furnace of on-the-spot application is by batch-type furnace, vertical heater, vertical cylindrical heater, large-scale side's stove etc. at present.But they can only adapt to a kind of heat medium, and disposable input cost is higher.The viscosity reduction technique of implementing has the technological measures such as ground watering, sleeve pipe dosing viscosity reduction, hollow rod.The problem existing is: the one, and water mixing temperature is low, and the loss of water mixing transfer heat especially is in the winter time large.The water mixing temperature of part well is also lower than the temperature of produced liquid in oil well, then causes the temperature of mixed liquor to reduce, and viscosity reducing effect is poor.The 2nd, sleeve pipe dosing exists that casing pressure is high can add the problems such as medicament, the easy frozen block of adding medicine pipeline in winter, and medicament price comparison is expensive, causes production cost to increase.The 3rd, hollow stem sealing and circulating heating process exists cost high, and heating power is low, needs often to add problems such as purifying demineralized water simultaneously, and field conduct has with certain limitation.For viscosity of crude, there is thermally sensitive feature, utilize heating furnace to heat up to produced liquid in oil well or water mixing, can obtain good viscosity reducing effect.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, has designed a kind of dual coil pipes heating furnace.
The utility model comprises: chimney, body of heater, outer coil pipe, inner coil pipe, base.Its annular dual coil pipes heating
The body of heater of stove is that cylinder and cone are formed by stacking, and top is provided with chimney, and the inner chamber of base is burner hearth, and the outer coil pipe of spring-like, inner coil pipe are set in together, and are arranged in body of heater.
The outer import of the outer coil pipe in above-mentioned dual coil pipes heating furnace is arranged on the bottom of body of heater, and outer vent is arranged on upper of furnace body.
The interior import of the inner coil pipe in above-mentioned dual coil pipes heating furnace is arranged on the bottom of body of heater, and inner outlet is arranged on upper of furnace body.
Outer coil pipe inner coil pipe in above-mentioned dual coil pipes heating furnace is also made as square or hexagon spring-like.
Body of heater in above-mentioned dual coil pipes heating furnace is also made as square or hexagon cylindrical shell and rectangular pyramid or hexagonal pyramid body and is formed by stacking.
The beneficial effects of the utility model are: novel structure, easy for installation, the thermal efficiency is high, long service life, can to produced liquid in oil well and water mixing, heat simultaneously, can effectively improve the temperature of mixed liquor, reduce viscosity of thickened oil and wellhead back pressure and the power consumption of ton liquid, can utilize high temperature water mixing to carry out heat for heavy oil wells and wash, save heavy oil wells heat and wash expense simultaneously.
Accompanying drawing explanation
The main TV structure schematic diagram of Fig. 1-the utility model.
In accompanying drawing, 1. chimney, 2. body of heater, 3. outer coil pipe, 301. outer imports, 302. outer vents, 4. inner coil pipe, 401. interior imports, 402. inner outlets, 5. base.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
Dual coil pipes heating furnace is comprised of chimney 1, body of heater 2, outer coil pipe 3, inner coil pipe 4, base 5.The body of heater 2 of its dual coil pipes heating furnace is for cylinder and cone are formed by stacking, and top is provided with chimney 1, and the inner chamber of base 5 is burner hearth, places natural gas stove and accessory, and the outer coil pipe 3 of spring-like, inner coil pipe 4 are set in together, and are arranged in body of heater 2.Respectively the outer import 301 of outer coil pipe 3, outer vent 302 are connected with oil pipeline, and import outside 301, outer vent 302 add respectively control valve, between add communicating valve, the interior import 401 of inner coil pipe 4 is connected with water mixing pipeline with inner outlet 402, and at interior import 401, inner outlet 402, add respectively control valve, between add communicating valve.
