Description
Technical field
The present invention relates to the petroleum recovering device field, especially a kind of electric heating of petroleum recovering well head crude oil, combustion gas heating apparatus.
Background technology
In the recover petroleum process, crude oil during from underground extraction because of being subjected to the influence of stratum and air themperature, its temperature reduces gradually, especially winter, the crude oil speed that temperature reduces in the transmission course in pipeline was faster, thereby on the oil pipeline inwall of outer wellhead, be easy to occur the wax deposition phenomenon, cause the reduction of oil transportation efficient, in order to prevent the wax deposition phenomenon, the oil exploitation mining site generally uses heating furnace that the well head petroleum pipeline is heated at present, heating furnace is mainly water batch heater, and water batch heater is to add coil pipe in the water jacket, in the water jacket after the water heating with heat transferred coil pipe inner fluid, this heating furnace is for yielding poorly, intermittently fuel-displaced oil well is inapplicable, fluid is heated when fuel-displaced, and furnace heat does not distribute and do not go out when fuel-displaced, causes the water jacket internal pressure too high dangerous, the bad adjustment of combusting firepower, the efficiency of heating surface is low, the equipment heaviness.Can produce a large amount of natural gases in the oil recovery process, in order to prevent the pollution to air, this part natural gas generally adopts firing 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 invention provides a kind of electric heating, combustion gas warmer of petroleum recovering well head, this warmer is efficiency of heating surface height, saving energy consumption not only, and security reliability height during to heating crude oil, can utilize the natural gas that produces in the oil recovery process that crude oil is heated, thereby reach the purpose of energy-saving and emission-reduction, and can realize the quick conversion of electrical heating and natural gas heating dual mode as required.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric heating of petroleum recovering well head, the combustion gas warmer, be provided with the heating work chamber, the indoor circulation pipe that is provided with of heating work, it is characterized in that circulation pipe is connected with the combustion of natural gas chamber, the heating work chamber is connected with the negative pressure service depot, negative pressure is equipped with petroleum pipeline in the service depot, the indoor superconductive medium that is full of of heating work, the indoor electric heating tube that is equipped with of heating work, the natural gas separator is installed outside the negative pressure service depot, and the natural gas separator is connected with burning shower nozzle in the combustion of natural gas chamber through appendix.
The invention has the beneficial effects as follows, efficiency of heating surface height, energy consumption are few, and has higher safety, simple in structure, can prevent petroleum pipeline wax deposition phenomenon effectively, can utilize the natural gas that produces in the oil recovery process that crude oil is heated, thereby reach the purpose of energy-saving and emission-reduction, and can realize the quick conversion of electrical heating and natural gas heating dual mode as required.
