Description
Technical field
The utility model relates to a kind of heater, and it is used for the heating of drilling mud jar mud.
Background technology
Oil field in China northeast and northwest, also will carry out drillng operation winter, icing for preventing that mud from freezing, and usually the heating installation pipeline inserted in the slurry tank and heat mud.The drawback of the method is that each drilling team all needs to be equipped with a cover steam generator system, will be equipped with the kettleman simultaneously.Winter, burning boiler caused environment pollution, and hot water piping needs insulation, and drilling team's removal of home the time will be reinstalled the boiler heating system, and workload is very big.
Summary of the invention
In view of heating mud in the above-mentioned php slurry jar will be equipped with the problem that a cover steam generator system occurs, the purpose of this utility model aims to provide a kind of drilling mud heater.Its principle is to utilize electric heater directly to heat conduction oil, then with hot oil pump with high temperature heat conductive oil squeeze into bore and slurry tank in heat exchange coil, make conduction oil by the drilling mud forced heat-exchanging in heat exchange coil and the slurry tank after, return in the heated tank.After the electric heater heating, squeeze into heat(ing) coil by hot oil pump once more, circulation heating so repeatedly, it is icing to prevent that mud from freezing, and has guaranteed normally carrying out of drillng operation.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drilling mud heater contains heated tank, hot oil pump, heat and changes coil pipe, control cabinet.Electric heating tube and temperature pick up are housed in the heated tank, are furnished with heat exchange coil in the slurry tank, heated tank feed liquor interface links to each other with the heat exchange coil liquid outlet, and heated tank goes out liquid interface and is connected with the hot oil pump intake; The holding wire of temperature pick up is connected with control cabinet.
Above-mentioned heat exchange coil can vertically be arranged in the interior periphery of slurry tank, or the horizontal bottom that is arranged in slurry tank,
Above-mentioned heat is changed coil pipe can adopt galvanized pipe, or finned tube, or screwed pipe.
The beneficial effect of advantage of the present utility model and generation is:
Drilling mud boiler heating in the past is to utilize natural gas or fuel oil (diesel oil or gasoline) as heating boiler fuel, and indirect heating water utilizes hot water to heat drilling mud by heat exchange again; With the utility model---the drilling mud heater is compared, this device heating process is more direct, plug the aviation plug of electricity cable, utilize the electric heating tube that the heating heat-conducting oil oil tank is equipped with in insertion directly to heat, the efficiency of heating surface is higher, because adopt heat-conducting oil heating, the temperature of heat transferring medium can reach 250 ℃, removed the water fouling of boiler heating simultaneously and added hot water temperature's height, the high accident potential that exists of boiler pressure.Under reliable condition of installing, this device non-environmental-pollution, simple and reliable for structure, process route is short, and heat waste is little; The reload temperature sensor can be controlled automatically, and drilling team's removal of home is installed simple, easy to operate, has alleviated labour intensity.

The specific embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, heat exchange coil 3 is φ 40mm, and L is the vertical interior periphery that is arranged in slurry tank of 150m galvanized pipe.Hot oil pump 2 is resistant to elevated temperatures centrifugal pump, and its power is 3Kw, and the heated tank volume is 0.5M
3,, the contain conduction oil is equipped with electric heating tube 5 and temperature pick up 6 in jar, and heated tank 1 feed liquor interface goes out liquid interface with heat exchange coil 3 and links to each other, and heated tank 1 goes out liquid interface and is connected with hot oil pump 2 intakes; Utilize and insert the electric heating tube 5 direct heating conduction oils that heating heat-conducting oil oil tank 1 is housed, conduction oil after the heating sucks hot oil pump 2, squeeze into heat exchange coil 3 in the slurry tank by hot oil pump 2, by with the mud heat exchange after return heated tank 1, finish a heating heat exchange cyclic process.Return the conduction oil of heated tank 1 and after electric heating tube 5 heating, squeeze into heat exchange coil 3 by hot oil pump 2 once more, circulation heating so repeatedly, the hydronic agitator that need start simultaneously on the slurry tank stirs repeatedly or starts sand pump and circulates, make mud be in flow regime, improve heat exchange efficiency, guarantee icing the freezing of mud in the drilling mud jar.
The holding wire 6 of temperature pick up is connected with control cabinet 4.The temperature sensor signal that utilizes band upper and lower limit electrical pickoff to export is controlled the startup of electric heating tube 5 and hot oil pump 2 and is stopped.Temperature upper and lower limit in the control cabinet 4 can be set, and is higher than on the design temperature in limited time thereby reach conduction oil temperature in the heated tank 1, stops hot oil pump 2 circulations and electric heating tube 5 and heats; The conduction oil temperature is lower than under the design temperature prescribes a time limit, and starts hot oil pump 2 and electric heating tube 5 heating, satisfies the purpose of controlling energy conservation automatically.
Embodiment 2
Heat is changed coil pipe 3 and is φ 40mm, and L is the horizontal bottom that is arranged in slurry tank of 100m screwed pipe.Hot oil pump 2 is a gear pump, and its power is 1.5Kw, and the heated tank volume is 0.2M
3,, temperature pick up 6 is installed in hot oil pump 2 exits.Conduction oil circulates as embodiment 1 in heat(ing) coil 3.Heated tank 1 outside need add insulation layer.Conduction oil can not be filled in the heated tank 1, leaves the space that conduction oil expands, and steam vent, dress breather and operation manhole are installed in top.
