The crude oil heating system is high in heating efficiency and low in energy consumption, can effectively avoid wax precipitation of oil conveying pipes and heat crude oil through natural gas generated during oil extraction, thereby achieving the aim of energy saving and emission reduction and being capable of rapidly switching between an electric heating mode and a natural gas heating mode as required.
Description
Technical field
The utility model relates to petroleum recovering device field, especially a kind of oil extraction well head crude oil heating system.
Background technology
In recover petroleum process, crude oil during from underground extraction because being subject to the impact of stratum and air themperature, its temperature reduces gradually, especially winter, the crude oil speed that in transmitting procedure, temperature reduces in pipeline was faster, thereby be easy to occur wax deposition phenomenon on the oil pipeline inwall of outer wellhead, cause the reduction of oil transportation efficiency, in order to prevent wax deposition phenomenon, oil exploitation mining site is generally used heating furnace to heat well head petroleum pipeline at present, heating furnace is mainly water batch heater, water batch heater is to add coil pipe in water jacket, in water jacket, after water heating, transfer heat to coil pipe inner fluid, this heating furnace is for yielding poorly, intermittently fuel-displaced oil well is inapplicable, when fuel-displaced, fluid is heated, when fuel-displaced, furnace heat does not distribute and does not go out, cause water jacket internal pressure too high dangerous, the bad adjustment of combusting firepower, the efficiency of heating surface is low, equipment is heavy.In oil recovery process, can produce a large amount of natural gases, in order to prevent the pollution to air, this part natural gas generally adopts combustion method that natural gas is burnt, and a large amount of natural gases is wasted in vain.
Summary of the invention
In order to overcome the above-mentioned technical deficiency of existing oil pipeline warmer, the utility model provides a kind of crude oil heating system, not only the efficiency of heating surface is high for this heating system, saving energy consumption, and security reliability is high during to heating crude oil, can utilize the natural gas producing in oil recovery process to heat crude oil, thereby reach the object of energy-saving and emission-reduction, and can realize as required the quick conversion of electrical heating and two kinds of modes of heated by natural gas.
The utility model solves the technical scheme that its technical problem adopts: a kind of crude oil heating system, be provided with gas fired-boiler, the outlet side that it is characterized in that combustion air intake pipeline and natural gas intake pipeline is arranged in the burner hearth of gas fired-boiler, the smoke vent opening of gas fired-boiler is connected with chimney through air-introduced machine, the oil-feed termination crude oil make-up pump of crude oil intake pipeline, the input of the heat-exchange tube of another termination gas fired-boiler of crude oil intake pipeline, the inlet port of the temporary tank of output termination of the heat-exchange tube of gas fired-boiler, the oil-out of temporary tank connects circulation pump through export pipeline, after straight-through valve is in parallel with electrical heating tank, its two ends connect respectively oil-out and crude oil export pipeline one end of circulation pump, the oil inlet pipe of another termination crude oil storage tank of crude oil export pipeline.
The beneficial effects of the utility model are, the efficiency of heating surface is high, energy consumption is few, and there is higher safety, simple in structure, can effectively prevent petroleum pipeline wax deposition phenomenon, can utilize the natural gas producing in oil recovery process to heat crude oil, thereby reach the object of energy-saving and emission-reduction, and can realize as required the quick conversion of electrical heating and two kinds of modes of heated by natural gas.
Accompanying drawing explanation
