Description

Technical Field

[0001] This utility model relates to the field of oilfield station production equipment, and more specifically, to an electromagnetic heating intelligent oil collecting, chemical dosing and pellet collecting device. Background Technology

[0002] In oilfield station production processes, various equipment combinations are required, including chemical dosing equipment, pigging equipment, heating equipment, and oil-gas separation equipment. In the chemical dosing stage, conventional dosing units need to be equipped with a stirring system, using a motor for active stirring to ensure thorough mixing of the added demulsifiers, wax removers, and other chemicals with the petroleum. Some chemicals, due to their properties, require matching temperatures, necessitating independent heating devices to promote dissolution and prevent freezing at low temperatures and decomposition at high temperatures. In the pellet collection stage, the general process requires pellet collection before chemical dosing; clean pellets must not enter the chemical mixing tank.

[0003] Oilfield station production systems require modular assembly. To accommodate universality and standardized interfaces, the integration and coupling between equipment are relatively low. Heating devices are needed for both reagent dosing and pellet collection, resulting in redundant configuration and resource waste. Furthermore, they cannot be linked with the heating process when oil enters the station, lacking intelligence and resulting in low heating efficiency. The mixing of reagents and oil requires active stirring by a motor, making the equipment complex. Utility Model Content

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figure 1As shown in the figure, an electromagnetic heating intelligent oil collecting, dosing and ball collecting device according to an embodiment of the present invention includes a heater 10, a first diverter 20, a stirrer 30, a second diverter 40, a flow limiter 50, a dosing device 60, a ball collecting cylinder 70, a dosing tank 80, and an oil storage tank 90. Heater 10 has a first inlet end and a first outlet end, and a first thermometer 11 is provided at the first inlet end; the first inlet end is used to introduce the oil to be treated, and heater 10 is used to heat the introduced oil; First distributor 20 has a second inlet end, a second outlet end and a first distributor port, the second inlet end is detachably connected to the first outlet end, and a second thermometer 21 and a first valve 22 are provided on the first distributor 20; the first distributor 20 is used to divide the fluid in the pipeline; Agitator 30 has a third inlet end and a third outlet end, and a drug inlet 31 is provided on the front side wall of agitator 30, the third inlet end is detachably connected to the second outlet end, and drug inlet 31 is used to introduce a preset drug; agitator 30 is used to fully mix the introduced preset drug and the oil divided by the first distributor 20; Ball collecting cylinder 7 The system is connected to the first diversion port, and the ball receiving cylinder 70 is used to collect the cleaning balls that have passed through the heater 10; the second diversion device 40 has a fourth inlet end, a fourth outlet end, and a second diversion port. The fourth inlet end is detachably connected to the third outlet end. The second diversion device is equipped with a second valve 41, and the fourth outlet end serves as an expansion interface for connection to an external pipeline; the dosing device 60 is connected to the dosing port 31 through a flow restrictor 50. The dosing device 60 is used to control the dosage, and the flow restrictor 50 is used to limit the flow rate and cross-sectional shape of the drug fluid; the drug storage tank 80 is connected to the dosing device 60 and is used to store the drug to be added and transport it to the agitator 30; the oil storage tank 90 is connected to the second diversion port of the second diversion device 40 and is used to store the finally processed oil. By simplifying the device and increasing its integration, this equipment allows the heater to be reused and can simultaneously perform auxiliary cleaning, oil heating, and drug dosing. Simultaneously, the internal flow guiding structure of the heater and agitator guides the oil to form a laminar flow state, improving heating and dosing efficiency. This solves the problems of low integration and low heating and dosing efficiency in existing oilfield station equipment.

[0027] In specific implementation, such as Figure 1 and Figure 2As shown, the heater 10 has a cylindrical structure. The outermost layer of the heater is an explosion-proof layer 12, which is mounted on a skid platform. The explosion-proof layer not only prevents overheating expansion caused by internal heating device failure but also provides support. The explosion-proof layer can be made of a relatively robust material. The second layer of the heater is an insulation layer 13, which is coaxial with the explosion-proof layer 12 and aligned at both ends. It is nested inside the explosion-proof layer 12 and is connected by adhesive to slow down heat loss. Inside the insulation layer, a spiral electromagnetic heating outer ring 14 is set. The spiral electromagnetic heating outer ring 14 is coaxial with the insulation layer 13 and aligned at both ends. It is connected by adhesive. The axial length of the spiral electromagnetic heating outer ring 14 is the same as the axial length of the insulation layer 13, ensuring that the device can provide a large heating area while being miniaturized.

[0028] Furthermore, such as Figure 2 As shown, the pipeline through which the oil flows is the oil conduit 15, which consists of a straight pipe 151 and a guide pipe 152. The straight pipe 151 is collinear with the outer ring 14 of the spiral electromagnetic heating and its two ends are aligned, and it is connected by adhesive. The straight pipe has a large diameter and is used to install other devices in the middle. The guide pipe 152 is shaped like a truncated cone. The larger end of the guide pipe 152 is welded to the straight pipe 151, and the smaller end is detachably connected to the first distributor 20 through a flange. The inner layer of the oil conduit 15 is the guide pipe 16, which is collinear with the axis of the oil conduit 15 and its two ends are aligned. The function of the guide pipe 16 is to guide the flow of oil. The guide pipe 16 and the oil conduit 15 are connected by welding.

[0029] Furthermore, such as Figure 2As shown, the guide pipe 16 includes a guide cylinder 161 and a guide plate 162. The guide cylinder 161 is disposed in the inner layer of the straight pipe 151, and is collinear with the axis of the straight pipe 151 and aligned at both ends. The guide plate 162 is disposed in the inner layer of the guide cylinder 161, and is collinear with the axis of the guide cylinder 161 and aligned at both ends. During the equipment production process, not only will there be viscous oil flowing, but also cleaning balls passing through the heater 10 to clean the pipe, which will have a large impact on the device inside the pipe. In order to ensure the reliability of the equipment during operation, the guide cylinder 161 and the guide plate 162, and the straight pipe 151 and the guide cylinder 161 are all connected by welding. The inner layer of the guide cylinder 161 is provided with a spiral guide groove 1611, which is a spiral groove. The spiral guide plate 162, which is a spiral-shaped long blade, serves as the first device inside the heater 10 to guide the flow of petroleum fluid. It is the second device inside the heater 10 to guide the flow of petroleum fluid. The spiral guide groove 1611 can be composed of multiple sets of grooves, and the guide plate 162 can be composed of multiple sets of blades. In this embodiment, six sets of grooves are used to form the spiral guide groove, and six sets of blades are used to form the guide plate 162. The common purpose of both the spiral guide groove 1611 and the guide plate 162 is to guide the petroleum to form laminar flow during its flow, avoiding turbulence and improving the heating efficiency of the petroleum in the pipeline, so that the liquid in the pipeline can be heated evenly. Simultaneously, when the cleaning ball is working, it can also guide the cleaning ball to rotate, improving the cleanliness of the pipeline.

[0030] Furthermore, such as Figure 2 The heater 10 also includes an inner heating cylinder 17, which is coaxial with the guide plate 162 and aligned at both ends. They are connected by welding. The inner heating cylinder 17 and the guide plate 161 together restrict the flow of oil. The inner heating cylinder 17 includes a support cylinder 171, a spiral electromagnetic heating inner ring 172, and a support cylinder end cylinder 173. The spiral electromagnetic heating inner ring 172 is coaxial with the support cylinder 171 and aligned at both ends. It is connected by adhesive and is located inside the support cylinder 171. It serves as an internal heating device and together with the spiral electromagnetic heating outer ring 14, it heats the fluid in the pipeline, further increasing the heating area. The cross-sectional shape of the fluid in the pipeline is cylindrical. Through double-layer heating, the device can be miniaturized while increasing the heating area and heating efficiency. The support cylinder end cylinder 173 is conical in shape to reduce the impact of the fluid in the pipeline. The support cylinder 171 and the support cylinder end cylinder 173 are welded at both ends.

[0031] Furthermore, such as Figure 3The agitator 30 includes an outer cylinder 32, an inner stirring device 33, and an end cylinder 34. The outer cylinder 32 is mounted on a skid-mounted platform and serves to fix and support the agitator 30. The inner stirring device 33 is coaxial with the outer cylinder 32 and is located inside the outer cylinder 32. The two are connected by welding. Oil heated by the heater is introduced from the third inlet end of the agitator 30 and initially mixed with the reagent entering through the inlet. After passing through the inner stirring device 33, the oil is fully mixed. The outer cylinder 32 and the end cylinder 34 are connected by welding at their respective ends. The end cylinder 34 is truncated cone-shaped. The larger end is welded to the outer cylinder 32, and the smaller end is the third outlet end, which is detachably connected to the fourth inlet end of the second distributor 40 via a flange.

[0032] Furthermore, such as Figure 4 The inner stirring device 33 includes: two support plates 331, a support shaft 334, multiple bearings 333, and multiple spiral fan blades 332; the two support plates 331 are located at both ends of the inner wall of the outer cylinder 32 of the stirrer and are connected by welding. The two support plates 331 are thin-walled straight plates arranged in a circle to fix the middle support shaft 334. The thin-walled shape is used to reduce axial impact during oil flow; the two ends of the support shaft 334 are fixedly welded to the center of the two support plates 331; the multiple spiral fan blades 332 are... Multiple bearings 333 are evenly spaced and rotatably arranged on the support shaft 334 along the axial direction of the support shaft 334. In this embodiment, two sets of spiral fan blades 332 and two sets of bearings 333 are used. The two sets of bearings 333 and the two sets of spiral fan blades 332 are arranged correspondingly. The spiral fan blades 332 are non-powered fan blades. During the oil flow process, the power of the oil flow is used to drive the spiral fan blades 332 to rotate. During the rotation of the spiral fan blades 332, the oil fluid is guided to form laminar flow, reducing turbulence and accelerating the mixing of the reagents.

[0033] Furthermore, such as Figure 5The flow restrictor 50 includes: two motors 51, two adjusting screws 52, a flow restrictor block 53, and a flow restrictor cylinder 54. The two ends of the flow restrictor cylinder are detachably connected to the dosing device 60 and the agitator 30 via flanges. A first flow restrictor hole 541 is provided in the middle of the flow restrictor cylinder 54, through which the agent dispensed by the dosing device 60 passes. The flow restrictor block is movably disposed within the flow restrictor cylinder 54 along its transverse direction. The flow restrictor block 53 has a second flow restrictor hole 531 corresponding to the first flow restrictor hole 541 and two adjusting holes 532 perpendicular to the second flow restrictor hole 531. The diameter of the second flow restrictor hole is the same as that of the first flow restrictor hole 541. Internal threads are provided in the two adjusting holes 532, connecting to the two motors 51 and the agitator 30. The adjusting screws 52 are connected by threads, and the two adjusting screws 52 are rotatably inserted into the two adjusting holes 532. The output shafts of the two motors 51 are fixedly connected to one end of the two adjusting screws 52 to drive the two adjusting screws 52 to rotate. The rotation of the two adjusting screws 52 drives the flow limiting block 53 to move to adjust the degree of overlap of the first flow limiting hole 541 and the second flow limiting hole 531 to limit the flow of oil. Different types of oil require different types and dosages of reagents. The flow limiter can accurately control the flow rate of the reagent entering the stirrer 30 from the inlet 31 by limiting the flow.

[0034] Furthermore, such as Figure 1 and Figure 2 The first thermometer 11 and the second thermometer 21 are used to measure the temperature of the oil entering and exiting the heater 10. The displayed temperature can be used to determine whether the heating process of the heater 10 has reached the temperature required for oil production, cleaning ball pipe cleaning and chemical dosing. The temperature of the fluid inside the pipeline can be affected by adjusting the outer spiral electromagnetic heating ring 14 and the inner spiral electromagnetic heating ring 172 to achieve intelligent production.

[0035] Furthermore, such as Figure 1 The dosing device 60 consists of a pump 62 and a flow meter 61. The dosing device 60 is detachably connected to the drug storage tank and the flow restrictor via a flange. The pump 62 can be used to provide kinetic energy to the drug fluid, and the flow meter 61 is used to monitor the amount of drug dispensed. Together, they are used to control the flow rate of the preset drug.

[0036] In operation, oil enters from the first inlet of heater 10. The explosion-proof layer 12 and insulation layer 13 protect the production environment. The outer spiral electromagnetic heating ring 14 and the inner spiral electromagnetic heating ring 172 work together to heat the oil. The oil passes through the guide pipe 16, forming a laminar flow state while being heated. The first thermometer 11 and the second thermometer 21 are used to measure the temperature of the oil entering and exiting heater 10. The temperature of the fluid inside the pipe is affected by adjusting the outer spiral electromagnetic heating ring 14 and the inner spiral electromagnetic heating ring 172 based on the displayed temperature. After being uniformly heated, the oil enters the stirrer 30 from the first distributor 20. The reagent... Simultaneously, the oil enters the inlet 31 from the storage tank 80 via the dosing device 60 and the flow restrictor 50, and is initially mixed with the petroleum. As the oil and chemical mixture flows forward, its own kinetic energy drives the spiral fan blades 332 on the inner stirring device 33. The rotation of the spiral fan blades 332 guides the oil and chemical mixture to form a laminar flow state, promoting thorough mixing of the chemical and oil. Afterward, the oil enters the storage tank 90 through the second diverter 40. When cleaning is required, the first valve 22 is closed, and the cleaning ball enters through the heater 10, then passes through the heater and the first diverter 20 and directly enters the ball receiving cylinder 70.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
