Description

Technical Field

[0001] The utility model relates to the technical field of oil increasers, and more specifically, to a super strong viscosity reducing and wax preventing oil increaser. Background Art

[0002] A super strong viscosity reducing and wax preventing oil increaser is a device used to improve the crude oil recovery rate and solve the problems of high viscosity and wax deposition encountered during the exploitation process. The super strong viscosity reducing and wax preventing oil increaser comprises components such as a vortex ejector, a vortex diversion groove, a flow-through nipple, an outer cylinder of a sonic oscillator, a support for a sonic vibration piece, and a jet generator. Through their coordinated use, the fluidity problem of crude oil can be improved, wax deposition in the pipeline can be reduced, and the oil well output can be increased.

[0003] When the existing super strong viscosity reducing and wax preventing oil increaser works, it is connected to a crude oil connecting pipe through an upper joint and a nipple. The crude oil is pumped through the connecting pipe and the upper joint into the nipple by starting a submersible pump on the surface of the connecting pipe. When the fluid passes through, the vortex ejector generates high-speed fluid flow to form a vortex, which helps to stir the crude oil and reduce the viscosity; the steel ball and the ball seat play a role in controlling the flow rate. When they flow into the vortex diversion groove and the flow-through nipple along the flow direction, they guide the fluid to form a vortex and enhance the mixing effect. When they enter the outer cylinder of the sonic oscillator, the support for the sonic vibration piece, and the sonic vibration piece, high-frequency sonic vibrations can be generated through their interaction to break the formation of wax crystals in the crude oil and promote the smoother flow of the crude oil.

[0004] In the actual use process of the existing technology, since wax and impurities contained in the crude oil adhere to the pipe wall of the flow-through nipple during the long-term flow of the crude oil, the effective flow area of the pipeline is easily reduced, the flow resistance is increased, and thus the crude oil flow rate drops. Therefore, a super strong viscosity reducing and wax preventing oil increaser is proposed now. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the utility model provides a super strong viscosity reducing and wax preventing oil increaser.

When the rotating blades and the stirring rod drive a plurality of stirring rods to rotate, the wax crystal structure and other solid particles in the crude oil can be broken, so that the crude oil is more uniformly mixed and local high-concentration wax deposition is reduced.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] (1) In this solution, the vortices formed by the flow of crude oil through fluid dynamics can drive the rotation of a plurality of rotating blades. When the rotating blades and the stirring rod drive the rotation of a plurality of stirring rods, the wax crystal structure and other solid particles in the crude oil can be broken, making the crude oil mix more evenly, reducing the high-concentration wax deposition in local areas. By stirring the crude oil, its fluidity can be further improved, making the more uniform and low-viscosity crude oil easier to be pumped to the ground, improving the pumping efficiency. At the same time, when the stirring rod rotates, it will drive the scraper to remove the deposits on the inner wall of the over-current short section, keeping the pipeline clean and avoiding blockage.

[0018] (2) Through the viscosity detector body, this solution can monitor the viscosity change of crude oil in real time and start or adjust the heating component as needed. When it is detected that the viscosity of the crude oil is too high, the spiral heating wire is started to heat the cooling oil, and the temperature can be transferred to the inside of the flow-through nipple through transmissive heating, enabling efficient heat transfer, ensuring uniform heating of the crude oil, thereby improving its heating efficiency. By heating, the formed wax crystals can be redissolved back into the crude oil, further reducing the possibility of wax deposition and keeping the pipeline unobstructed. The heat preservation layer on the surface of the heating chamber can effectively reduce the loss of heat to the external environment.

[0019] (3) At the same time, when the rotating rod drives the stirring rod and the scraper to rotate, it can not only stir the crude oil, but also repeatedly bring the crude oil into contact with the inner wall of the heated flow-through nipple, thereby making more efficient use of heat, quickly reducing the viscosity of the crude oil, and improving the fluidity and anti-wax effect.

[0030] Embodiment 1

[0031] Referring to Figures 1 - 5 , which is the first embodiment of the present utility model. This embodiment provides a super strong viscosity reducing, wax preventing and oil increasing device, including an upper joint 1 and a short section 101. The short section 101 is installed inside the upper joint 1, and an overcurrent short section 104 is installed inside the short section 101. A stirring assembly 2 is installed inside the overcurrent short section 104.

[0032] Specifically, the stirring assembly 2 includes a support plate 201 fixedly installed on the inner wall of the flow-through nipple 104. The upper surface of the support plate 201 is rotatably connected to a stirring rod 202 through a bearing seat. The outer surface of the stirring rod 202 is fixedly connected with stirring rods 204. The outer surface of the stirring rod 202 is fixedly connected with a plurality of rotating blades 203 near the upper end of the stirring rod 204. The rotating blades 203 are inclined. The outer surface of the stirring rod 204 is fixedly connected with a scraper 205. A viscosity detector body 206 is installed inside one of the stirring rods 204. An eddy current injector 102 is installed inside the nipple 101. A ball seat 1031 is installed on the central axis inside the nipple 101. A steel ball 103 is installed on the outer surface of the ball seat 1031. An eddy current diversion groove 1032 is installed between the inner cavities of the nipple 101 and the flow-through nipple 104.

[0033] Further, the vortex of the crude oil drives the plurality of rotating blades 203 to rotate. When the rotating blades 203 rotate, they drive the stirring rod 202 to rotate. When the stirring rod 202 rotates, it drives the stirring rod 204 to rotate. When the stirring rod 204 rotates, it drives the scraper 205 to scrape off the crude oil deposits adhering to the inner wall of the flow-through nipple 104, keeping the pipeline clean. At the same time, the stirring rod 204 stirs the crude oil to break the wax crystal structure.

[0034] Embodiment 2

[0035] Refer to Figures 1 - 5 , which is the second embodiment of the present invention. Based on the previous embodiment, a heating assembly 3 is installed on the outer surface of the flow-through nipple 104.

[0036] Specifically, the heating assembly 3 includes a heating chamber 301 fixedly installed on the outer surface of the flow-through nipple 104. A spiral heating wire 302 is installed inside the heating chamber 301. The outer surface of the heating chamber 301 is fixedly connected with a heat preservation layer 303. The heat preservation layer 303 is made of heat preservation materials. An acoustic oscillator outer cylinder 105 is installed inside the flow-through nipple 104. An acoustic vibration piece bracket 1051 is installed inside the acoustic oscillator outer cylinder 105. A jet generator 1052 is installed at the bottom of the acoustic vibration piece bracket 1051. An acoustic vibration piece 1053 is installed on the upper surface of the acoustic vibration piece bracket 1051.

[0037] Further, the viscosity detector body 206 is used to monitor the viscosity of the crude oil in real time. When the viscosity of the crude oil is high, the spiral heating wire 302 is started to heat the cooling oil in the heating chamber 301. Its temperature can be transferred through heat transfer to the inside of the flow-through nipple 104 for heating. The rotating scraper 205 repeatedly contacts the liquid in the flow-through nipple 104 with its inner wall to ensure uniform heat distribution.

[0038] Working principle: During use, by connecting the upper sub - joint 1 and the nipple 101 to the crude oil connecting pipe, a complete fluid channel is formed. Start the oil pump on the surface of the connecting pipe, and the crude oil enters the nipple 101 through the connecting pipe and the upper sub - joint 1. When the crude oil passes through, the eddy current ejector 102 generates high - speed fluid flow, forming an eddy current, which helps to stir the crude oil, reduce its viscosity, and thus can initially break up the wax crystal structure in the crude oil, promoting more uniform mixing. The flow rate and pressure of the fluid are adjusted by the steel ball 103 and the ball seat 1031 to prevent the flow rate from being too fast or too slow from affecting the treatment effect and ensure an appropriate residence time of the crude oil in the equipment. When it flows into the eddy current diversion groove 1032 and the flow - through nipple 104 along the flow direction, it guides the fluid to form an eddy current, enhancing the mixing effect. At the same time, the rotation of the multiple rotating blades 203 is driven by the crude oil vortex. When the rotating blades 203 rotate, they drive the stirring rod 202 to rotate. When the stirring rod 202 rotates, it drives the stirring bar 204 to rotate. When the stirring bar 204 rotates, it drives the scraper 205 to scrape off the crude oil deposits adhering to the inner wall of the flow - through nipple 104, keeping the pipeline clean. At the same time, the stirring bar 204 stirs the crude oil, destroying the wax crystal structure.

[0039] Meanwhile, the viscosity detector body 206 monitors the viscosity of the crude oil in real - time. If the viscosity of the crude oil is high, the spiral heating wire 302 is started to heat the cooling oil in the heating chamber 301. Its temperature can be transferred to the inside of the flow - through nipple 104 through transitive heating. The rotating scraper 205 repeatedly contacts the liquid in the flow - through nipple 104 with its inner wall to ensure uniform heat distribution and improve the heating efficiency. The heat preservation layer 303 on the surface of the heating chamber 301 can effectively reduce the heat dissipation to the external environment. When it enters the area of the acoustic oscillator outer cylinder 105, the acoustic vibration piece support 1051, and the acoustic vibration piece 1053, high - frequency acoustic vibrations are generated to destroy the formation of wax crystals in the crude oil and prevent wax deposition. The jet generator 1052 provides high - pressure jets to strongly stir the crude oil, increasing its fluidity and promoting the smoother flow of the crude oil.

[0040] The above - mentioned is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent replacements or changes, and all should be covered by the protection scope of the present utility model.
