Description

Technical Field

[0001] The utility model relates to the technical field of oil production equipment, in particular to a vortex type wax prevention and viscosity reduction device for an oil pumping pipe. Background Art

[0002] The crude oil produced by most of my country's oil fields has the characteristics of high wax content, high pour point and high viscosity. At room temperature, the fluidity of this type of oil is quite poor, so transportation through gathering pipelines becomes a difficult point, especially the distance from the wellheads to the metering stations. Therefore, viscosity reduction is a key issue in the extraction and transportation of heavy oil.

[0003] During the long-distance transportation of crude oil through pipelines, changes in external conditions such as temperature and flow rate lead to increased crude oil viscosity, wax deposition on the pipe walls, and increased flow resistance. This affects the normal gathering and transportation of crude oil, reduces crude oil gathering and transportation capacity, increases crude oil gathering and transportation energy consumption, and may even cause pipeline blockage accidents, posing a great safety hazard to crude oil transportation. Currently, most methods used to reduce viscosity and prevent wax are mechanical and chemical, which are not only labor-intensive and time-consuming, but also have poor results. Utility Model Content

[0004] The purpose of the utility model is to provide a vortex type anti-wax viscosity reduction device for oil pumping pipes to solve the problem in the above background technology that most of the current methods of viscosity reduction and anti-wax are mechanical, chemical, etc., which are not only labor-intensive and time-consuming but also have poor effects.

[0005] The utility model provides the following technical solution: a vortex type anti-wax viscosity reduction device for an oil pumping pipe, comprising an upper shell, a lower shell provided at the lower end of the upper shell, internal threads provided at both ends of the upper shell and the lower shell, and an anti-wax viscosity reduction mechanism provided inside the upper shell and the lower shell; the anti-wax viscosity reduction mechanism comprises a clamping groove, a mounting bracket, a turbofan, and a constant temperature heating pipe. The upper shell and the lower shell are provided with a clamping groove inside, the mounting bracket is clamped inside the clamping groove, the turbofan is mounted on one end of the mounting bracket, and two constant temperature heating pipes are provided on the left and right sides of the turbofan, respectively. Due to the arrangement of the turbofan, after the oil enters the anti-wax viscosity reduction device, the oil forms a vortex state after passing through the turbofan, thereby breaking up paraffin molecules accumulated in the oil and preventing the paraffin from agglomerating into large clumps and condensing on the pipe wall to cause blockage. At the same time, the constant temperature heating pipes provided on both sides of the turbofan can heat the oil, thereby reducing the viscosity and freezing point of the crude oil, softening and destroying the wax layer, and preventing the surface aggregation of paraffin molecules, thereby achieving the effect of reducing viscosity and preventing wax.

[0006] Preferably, the interior of the upper shell and the lower shell is wrapped with a carbon felt insulation layer, and the outer end of the carbon felt insulation layer is wrapped with an asbestos insulation layer. Through the coordinated arrangement between the carbon felt insulation layer and the asbestos insulation layer, the interior of the device is easily insulated, avoiding heat loss resulting in poor heating effect, increased oil viscosity, and wax deposition on the pipe wall that affects use.

[0007] Preferably, an upper connecting plate is provided at each of the left and right ends of the upper shell, and a lower connecting plate is provided at each of the left and right ends of the lower shell; a plurality of connecting holes are provided at the upper ends of the upper connecting plate and the lower connecting plate, and the inner ends of the connecting holes are connected with connecting bolts. The setting of the connecting holes facilitates the connection of the upper connecting plate and the lower connecting plate together by connecting bolts, thereby completing the assembly of the device.

[0008] Preferably, the outer end of the lower part of the connecting bolt is connected to a connecting screw sleeve through a thread, the lower end of the connecting screw sleeve is provided with a hand wheel, and the interior of the connecting screw sleeve is provided with a thread to facilitate connection with the connecting bolt through the thread.

[0009] Preferably, the outer end of the hand wheel is evenly provided with a plurality of grooves for facilitating finger rotation. The provision of the plurality of grooves facilitates the user to rotate the connecting screw sleeve through the hand wheel to complete assembly or disassembly.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The coordination between the carbon felt insulation layer and the asbestos insulation layer facilitates heat preservation inside the device, preventing heat loss and poor heating effect, which leads to increased oil viscosity and wax deposition on the pipe wall, thus improving the practicality of the eddy current anti-wax and viscosity reduction device for oil pumping pipes;

[0012] 2. When the turbofan or constant temperature heating tube inside the anti-wax viscosity reduction device is damaged and needs to be replaced, it is convenient to disassemble and replace. BRIEF DESCRIPTION OF THE DRAWINGS

Fan 6, two constant temperature heating tubes 7 are respectively provided on the left and right sides of the turbofan 6. Through the setting of the turbofan 6, after the oil body enters the anti-wax viscosity reduction device, the oil forms a vortex state after passing through the turbofan 6, thereby breaking up the paraffin molecules gathered in the oil, and preventing the paraffin from gathering into large clumps and condensing on the pipe wall to cause blockage. At the same time, the constant temperature heating tubes 7 provided on both sides of the turbofan 6 can heat the oil, which can reduce the viscosity and freezing point of the crude oil, and at the same time, soften and destroy the wax layer, which is not conducive to the surface aggregation of paraffin molecules, thereby playing a role in viscosity reduction and wax prevention.

[0020] Preferably, the interior of the upper shell 1 and the lower shell 2 is wrapped with a carbon felt insulation layer 8, and the outer end of the carbon felt insulation layer 8 is wrapped with an asbestos insulation layer 9. The coordinated arrangement between the carbon felt insulation layer 8 and the asbestos insulation layer 9 facilitates insulation of the interior of the device, avoids heat loss resulting in poor heating effect, increased oil viscosity, and wax deposition on the pipe wall that affects use.

[0021] Preferably, an upper connecting plate 10 is provided at each of the left and right ends of the upper shell 1, and a lower connecting plate 11 is provided at each of the left and right ends of the lower shell 2; the upper ends of the upper connecting plate 10 and the lower connecting plate 11 are provided with a plurality of connecting holes 12, and the inner ends of the connecting holes 12 are connected with connecting bolts 13. The setting of the connecting holes 12 facilitates the connection of the upper connecting plate 10 and the lower connecting plate 11 together through the connecting bolts 13, thereby completing the assembly of the device.

[0022] Preferably, the outer end of the lower portion of the connecting bolt 13 is connected to a connecting screw sleeve 14 via a thread, a hand wheel 15 is provided at the lower end of the connecting screw sleeve 14, and a thread is provided inside the connecting screw sleeve 14 to facilitate connection with the connecting bolt 13 via the thread.

[0023] Preferably, the outer end of the hand wheel 15 is evenly provided with a plurality of grooves for easy rotation by fingers. The provision of the plurality of grooves makes it easy for the user to rotate the connecting screw sleeve 14 through the hand wheel 15 to complete assembly or disassembly.

[0024] When the utility model is in use, the anti-wax viscosity reduction device is connected to the oil pumping pipe through the internal threads 3 at both ends for use. The turbofan 6 is set so that after the oil body enters the anti-wax viscosity reduction device, the oil forms a vortex state after passing through the turbofan 6, thereby breaking up the paraffin molecules gathered in the oil, and preventing the paraffin from gathering into large clumps and condensing on the pipe wall to cause blockage. At the same time, the constant temperature heating tubes 7 set on both sides of the turbofan 6 can heat the oil, which can reduce the viscosity and freezing point of the crude oil, and at the same time soften and destroy the wax layer, which is not conducive to the surface aggregation of paraffin molecules, and plays the role of reducing viscosity and preventing wax. The coordinated setting between the carbon felt insulation layer 8 and the asbestos insulation layer 9 facilitates the insulation of the interior of the device to avoid heat loss and improve the heating effect. Poor quality leads to increased oil viscosity and wax deposition on the tube wall, which affects its use. When the turbofan 6 or the constant temperature heating tube 7 inside the anti-wax viscosity reduction device is damaged and needs to be replaced, the user can drive the connecting screw sleeve 14 to rotate by turning the hand wheel 15, thereby removing the connecting screw sleeve 14, and then pull out the connecting bolt 13 to separate the upper shell 1 and the lower shell 2. The user can then clean the inside of the device and replace the damaged parts. After the replacement is completed, the upper shell 1 and the lower shell 2 can be put together to align the upper connecting plate 10 and the lower connecting plate 11, and then insert the connecting bolt 13 into the connecting hole 12, and turn the hand wheel 15 to drive the connecting screw sleeve 14 and the connecting bolt 13 to connect together, thereby completing the assembly.
