Description
The utility model relates to a kind of electric heater unit that is used for oil, gas well manufacturing process to well head oil (gas) muzzle position heat-preserving anti-freezing.
In oil, gas well manufacturing process, in order to control produce oil, gas output, guarantee the exploitation steady in a long-term under rational working system of oil, gas well, generally need on well head production tree or well site fuel-displaced (gas) pipeline, install oil (gas) mouth.Because oil (gas) mouth aperture is less, the gas flow at this position of flowing through is bigger, and flow velocity is higher, and oil gas is after through oil (gas) mouth, and it is big that flow area becomes suddenly, and flow velocity reduces, and absorbs a large amount of heats, causes near temperature decrease oil (gas) muzzle.As not taking the heat tracing measure, then very easily freeze to stop up influence oil, gas well ordinary production for this kind process of refrigerastion.At present, the on-the-spot heat tracing mode such as water jacket furnace that adopts usually prevents that oil (gas) muzzle position from freezing, but needs greatlyyer with equipment volume, and thermal loss is more, and cost of production is higher.
The purpose of this utility model is to provide that a kind of volume is less, concentrate at the heating position, high, the lower-cost combined type oil of the thermal efficiency, gas well mouth electric heater.
The utility model is to realize like this.This kind combined type oil gas well well head electric heater is made up of parts such as outer tube, heating outer tube, heating lumen, electrical bar sleeve pipe, electrical bar and plug flange, electrothermal piece plug, inner chamber plug, electrical bar plug, insulation shutoff, between outer tube and heating outer tube and heating lumen front end, heat outer tube and heat between the lumen and constitute outer ring space and interior annular space respectively.Electrical heating elements is annular space and sealing and fixing in plug with holes penetrates, and falling heat-transfer oil is as the heat conduction carrier in the interior annular space, and filled heat insulating material (rock wool) in the outer ring space prevents that heat from distributing.This heaters set is contained in well mouth of oil well fuel-displaced (gas) Oil of Oil Pipeline (gas) muzzle outside, and whole heater is provided with 3 fairleads altogether, and one of them is drawn with fuel-displaced (gas) pipeline through inside and outside annular space from oil (gas) muzzle side and is connected; Heating lumen side from the interior annular space outside is drawn through outer ring space; Another is then drawn from oil (gas) mouth coaxial direction, installation intake as heating, latter two fairlead all can be used as oil-gas pipeline and uses, can according to circumstances use one of them, another fairlead is then screwed on the thread protector cap as standby, and two fairleads can use simultaneously when the gas production extra-high-speed.During this electric heater work, the electrical bar heating of power supply energising back, with the heat-conducting oil heating in the annular space in this heater, form the high-temperature area of an annular, can to suit within it oil (gas) muzzle and the oil-gas pipeline of front and back heat, prevent frosting, freeze the generation of phenomenon, guarantee oil, gas well ordinary production.
The utility model volume is little, and compact conformation is easy to implement, and convenient management heats effectively, utilizes it can solve oil, gas well mouth oil (gas) muzzle position frozen problem effectively, guarantees oil, gas well ordinary production.This device cost of manufacture is low, and obvious energy conservation is suitable for and applies.
Accompanying drawing is a general structure schematic diagram of the present utility model.Among the figure, label " 20 " is oil (gas) mouth, and " 22 " are oil (gas) muzzle, and " 23 " are oil (gas) muzzle plug.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of insulation plug 1, electrical bar plug 2, tubing coupling 3, tubing nipple 4, plug flange 5, sealing mat 6, overcoat flange 7, bolt 8, outer tube 9, heat preservation rock 10, heating lumen 11, temperature pick up 12, sensor sleeve 13, heating outer tube 14, conduction oil 15, electrical bar sleeve pipe 16, electrical bar 17,28, magnesia 18, fairlead 19,25, inner chamber plug 21, thread protector cap 24, fairlead 26, electrical bar connector lug 27 and electrothermal piece plug 29.Its assembling, architectural feature are as follows: be provided with heating outer tube 14 in the outer tube 9, be provided with heating lumen 11 in the heating outer tube 14; Outer tube 9 left ends are equipped with overcoat flange 7 and plug flange 5, are provided with sealing mat 6 therebetween, and connect with bolt 8 fastening, the right-hand member plug flange 5 that is welded, outer tube 9 left bottom are provided with a mouth of pipe that is used for picking out fairlead 19; Heating outer tube 14 two ends be welded respectively electrothermal piece plug 29 and inner chamber plug 21, left end top penetrates sensor sleeve 13, wherein be provided with temperature pick up 12 (this sensor lead-out wire is connected with power supply), the bottom penetrates electrical bar 28, electrical bar 28 outsides are provided with the connector lug 27 that picks out lead-in wire usefulness, and the top, right side has a mouth of pipe that picks out fairlead 19; Heating lumen 11 left ends and the tubing nipple 4 inserting ends welding that penetrates in it, right-hand member is welded on oil (gas) muzzle 22 front sides, heating lumen 11 left bottom and oil (gas) muzzle 22 tops are welded with fairlead 25,19 respectively, and thread protector cap 24 is equipped with in fairlead 25 lower ends; In the space between outer tube 9 and heating outer tube 14 and the heating lumen 11 heat preservation rock 10 is housed, in the space between heating outer tube 14 and the heating lumen 11 conduction oil 15 is housed; Tubing nipple 4 left ends link to each other with tubing coupling 3 right-hand members with screw thread, and tubing coupling 3 left ends are equipped with electrical bar plug 2, and rubber mass insulation shutoff 1 is equipped with in electrical bar plug 2 outer ends; Electrical bar 17 is packed into from electrical bar sleeve pipe 16 left ends in it, and graininess magnesia 18 is housed in the sleeve pipe 16, in order to play a thermolysis.
