Abstract
The utility model relates to a crude oil heating device for oil production well heads and oil pipelines in oil fields. The utility model is characterized in that a casing is composed of a circular cylinder wall and sealing ends at both ends, and the casing is fixed on a base, forming a lower water chamber; the sealing end at the lower end is provided with a plurality of circular holes which are connected with one end of a heat-transfer pipe which is filled with flowing heat medium, one side of an upper water chamber in the casing is provided with a plurality of holes which are connected with the other end of the heat-transfer pipe, and the other side of the upper water chamber is provided with a hole connected with a connecting pipe which passes through the sealing end at the upper end of the casing; one side of the lower water chamber is fixed with a heating element, and the other side and the bottom are respectively provided with a hole respectively connected with a water inlet pipe and an elbow pipe. The utility model has the advantages of quick temperature rise, high heat efficiency, uniform heating, convenient maintenance, low cost and long service life. The utility model can be used for heating crude oil of different qualities and reducing viscosity, keeping the pipelines smooth; the utility model is especially suitable for pipelines in low-temperature oil fields.
Description
The utility model relates to oil well mouth and oil pipeline raw oil heater.
At present, in the oil field oil recovery conveyance conduit,, make crude oil flow not smooth, even solidify, cause line clogging because crude oil viscosity difference adds some ground low temp area.Stop up for fear of oil pipeline, generally adopt water batch heater and electric tube heater, the thermal efficiency is low, and it keeps in repair inconvenient, the maintenance cost height; Electric tube heater sometimes electrothermal tube fragile be difficult for found to cause line clogging by the people, the life-span is short.
The purpose of this utility model is exactly that a kind of not fragile, easy-maintaining, long production wellhead Crude oil heater of life-span are provided in order to overcome the deficiencies in the prior art.
The purpose of this utility model reaches by the following technical programs: it is made up of housing, heating element, oil inlet pipe, flowline, its middle shell is made up of the end socket at round tube wall and two ends, be fixed on the base, form lower header, heat-transfer pipe is some, be arranged in the housing, housing lower end end socket is opened heat-transfer pipe one end that flowing heat medium is arranged in several circular holes connections; Upper tank one side that is arranged in the housing is opened the several holes connection heat-transfer pipe other end, and the upper tank opposite side is opened a hole and connected the adapter of passing housing upper end end socket; Lower header one side is heating element fixedly, and opposite side is opened a hole and connected water inlet pipe, and a hole bridge piece is opened in its bottom.
The utility model compared with prior art has following advantage: owing to adorn thermal medium anti-icing fluid or water in the heat-transfer pipe, switch on back 30 minutes oil pipelines of heater element can reach the temperature value of design, can add hot oil wells oil pipeline crude oil effectively, need not special messenger operation, reduce the amount of labour and do not damage; Moreover this heater is easy to maintenance, only needs to change heating element or thermal medium, and workload is little, and expense is low, and the life-span is long.
Accompanying drawing 1 is a structure chart of the present utility model;
Accompanying drawing 2 is the utility model A-A cut-away views.
The utility model is described in further detail below in conjunction with accompanying drawing:
In the accompanying drawing 12, housing 9 is welded by the end socket at round tube wall and two ends, be fixed on the base 12, form lower header 1, heat-transfer pipe 3 is some, be arranged in the housing 9, the circular hole that housing 9 lower end end sockets have with heat-transfer pipe 3 radicals equate is connected to pass and is welded on plate 10 that several nozzle openings 14 are arranged on housing 9 inwalls and fixing heat-transfer pipe 3 one ends; Upper tank 4 one sides that are arranged in the housing 9 are opened the other end that the circular hole that equates with heat-transfer pipe 3 radicals is connected heat-transfer pipe 3, upper tank 4 opposite sides are opened a circular hole and are connected the adapter 6 of passing housing 9 upper end end sockets, take over an end of 6 and connect pressure transmitter, outage when being used to control housing 9 internal pressures and overflowing; Lower header 1 one sides are opened a hole and are connected water inlet pipe 5 with the fixing heating element 11 of screw, opposite side, and an end of water inlet pipe 5 connects valve and funnel, is used to add flowing heat medium anti-icing fluid or water; The bottom of lower header 1 is an inclined-plane and opens a hole bridge piece 12 at the inclined-plane lower, is used for conveniently taking out stains.Flowline 8 is provided with temperature pick up 7 with the interface of housing 9, is used to control housing 9 interior temperature and cuts off the power supply self-opening power supply when being lower than design load automatically above design load.Heating element 11 is connected in the control cabinet.The selection of pipe seamless steel pipe wherein, the seamless steel plate of board selection.
When this heater is installed, should be at first with on, lower header (4,1) and heat-transfer pipe 3 clean up, after the pressure testing of dress water is put only, pour anti-icing fluid into from managing 5 funnel again, sealing then, by the steering handle oil pipeline of crude oil flow with advance, flowline (2,8) connect, open into, flowline (2,8) valve, this moment, crude oil entered in the housing 9 of heater, and this moment, temperature was lower than set temperature value, signal passes to the control cabinet self-opening power supply by temperature pick up 7, crude oil is realized turbulent condition by nozzle opening 14 oil spout in housing 9 on the dividing plate 10, makes crude oil steady flow in housing 9.Energising back heating element 11 is heated anti-icing fluid, and the anti-icing fluid temperature is risen, and passes to the crude oil heat by heat-transfer pipe 3 walls, every stream, better forms convection circulation by dividing plate 15, realizes oil pipeline and well head pipeline heating crude oil.When temperature in the housing 9 surpassed design load, signal passed to control cabinet by temperature pick up 7 and cuts off the power supply automatically, and heating stops, and has so just reached the purpose of heating; When housing 9 internal pressures surpassed design load, pressure transmitter passed to control cabinet to signal and cuts off the power supply automatically.
In use, heating element 11 and thermal medium should be made regular check on, and only need unload the screw of heating element 11 when needing to change, heating element 11 maintenances or replacing; Thermal medium only need be opened bend pipe 13 and bleed off, and pours thermal medium into and gets final product from managing 5 funnel again.
This heater can be installed in stripper well, heavy oil wells, edge well, individual well and draw the wet goods well head, improves the pipeline crude oil temperature in the feeder line, avoids oil transportation wax deposition midway, and it is not smooth to flow, and the frozen plug pipeline is to realize not having stifled oil-collecting and carry at a distance.
