Description

Technical Field

[0001] The present invention belongs to the technical field of oil extraction equipment, and particularly relates to a scale and wax prevention processor for oil wells and its usage method. Background Art

[0002] During the oil extraction process, crude oil often contains a certain proportion of paraffin and other impurities. With the decrease in temperature or pressure change, these components are prone to form deposits inside the oil pipe, pump, and other transportation equipment, resulting in pipeline blockage, equipment wear, and production efficiency decline. Especially for deep wells and oil wells in low-temperature environments, the problem of wax deposition is particularly serious, seriously affecting the normal production and maintenance cost of oil wells.

[0003] Existing Solutions and Their Limitations Mechanical wax removal: Traditional mechanical methods include tools such as wax scrapers and spiral brushes, which remove the wax layer inside the pipeline by physical means. However, this method is complex to operate, has a high labor intensity, and it is difficult to completely remove all wax, and it may also cause damage to the pipeline.

[0004] Thermal wax removal: Using steam, hot water, or electric heating to increase the oil temperature, so that the wax softens and is discharged. Although the effect is good, the energy consumption is high, and additional heat source equipment is required, increasing the operating cost.

[0005] Chemical solvent wax removal: Using specific chemical solvents to dissolve wax. This method has good dissolution ability, but improper selection and use of chemical solvents may cause environmental pollution, and there are also safety hazards, such as corroding equipment and affecting human health.

[0006] Combined treatment: Some advanced systems combine multiple wax removal means, such as first dissolving wax with chemical solvents and then performing mechanical cleaning. Although the treatment efficiency is improved, the equipment complexity increases, the maintenance difficulty is large, and the one-time investment is relatively high. Summary of the Invention

[0026] Please refer to Figures 1-8 , the present invention provides the following technical solutions: An oil well scale and wax prevention processor, comprising: A protective outer cylinder 1; An upper cover 101, the upper cover 101 is threadedly connected to the upper end of the protective outer cylinder 1 by bolts, and the lower end of the protective outer cylinder 1 is threadedly connected with a lower cover 102 by bolts; A crushing chamber 2, the crushing chamber 2 is arranged inside the protective outer cylinder 1, the upper end of the crushing chamber 2 is threadedly connected with a first upper plate 201 by bolts, a liquid inlet pipe 202 and a gas inlet pipe 203 are arranged at the upper end of the first upper plate 201, and both the liquid inlet pipe 202 and the gas inlet pipe 203 penetrate through the upper cover 101 and extend upwards; A crushing mechanism, the crushing mechanism includes a connecting column 204, a crushing auger 205, a vertical frame 206, a crushing component and a driving component; A wax melting mechanism, the wax melting mechanism is arranged at the lower end of the crushing chamber 2 for producing solution wax in the crushing chamber 2; An exhaust mechanism, the exhaust mechanism is flange-connected to the lower end of the wax melting mechanism for air circulation of the production liquid after wax melting; A heating mechanism, the heating mechanism is arranged at the lower end of the exhaust mechanism for heating the downhole production liquid; and A second upper plate 405, the second upper plate 405 is flange-connected to the lower end of the heating mechanism to realize the transportation of the downhole production liquid.

[0027] In a specific embodiment of the present invention, the protective outer cylinder 1 serves as the basic structure of the entire processor. The protective outer cylinder 1 provides necessary protection and support for the internal components. The upper end is connected to the upper cover 101 by bolt threading, and the lower end is connected to the lower cover 102 by bolt threading. This design facilitates disassembly and maintenance. The upper cover 101 is installed on the top of the protective outer cylinder 1 to enclose the system and support the access of the liquid inlet pipe 202 and the gas inlet pipe 203. The lower cover 102 is located at the bottom of the protective outer cylinder 1 and is connected to the exhaust mechanism to ensure the sealing of the system and facilitate the discharge of liquid and gas. The crushing chamber 2 is arranged inside the protective outer cylinder 1 and is the first station of the processing flow. The upper end of the crushing chamber 2 is connected to the first upper plate 201 by bolt threading to ensure stable installation and easy disassembly for cleaning or replacing components. It is responsible for initially crushing large impurities in the production liquid to prepare for subsequent processing steps. The crushing mechanism includes a connecting column 204, a crushing auger 205, a vertical frame 206, crushing components, and a driving component. The motor 104 drives the crushing auger 205 to rotate through the driving component to crush the impurities in the production liquid entering the crushing chamber 2. The crushing components such as the rectangular plate 2071, the smooth rod 2072, the spring 2073, etc. work together to ensure that large impurities are effectively crushed into small particles, improving the efficiency of subsequent processing. The wax dissolving mechanism uses chemical solvents to dissolve the wax components in the production liquid. An appropriate amount of chemical solvent is injected through the chemical solvent inlet pipe 304, and the solvent is evenly sprayed on the surface of the production liquid by using the funnel 302 and the chemical solvent spraying pipe 303 to accelerate the wax dissolving process. The chemical solvents can be the following several types: 1. Organic solvents Toluene: A common organic solvent with good dissolving ability, which can effectively dissolve paraffin and other long-chain hydrocarbon substances. It is widely used as a wax dissolving agent in the petroleum industry.

[0028] Xylene: Similar to toluene, but with lower volatility, suitable for situations where a longer acting time is required.

[0029] n-Heptane or isooctane: These light hydrocarbon solvents have good dissolving effects on paraffin and are relatively safe and environmentally friendly.

[0030] 2. Surfactant solutions Non-ionic surfactants: Such as polyoxyethylene ether compounds, which can reduce the interfacial tension between water and wax, making the wax easier to disperse and dissolve in water. These solvents are usually used in water-based systems, reducing the impact on the environment.

[0031] Cationic or anionic surfactants: Select an appropriate type according to the specific characteristics of the production liquid to enhance its interaction with the wax components.

[0032] 3. Biodegradable solvents Vegetable oil-based solvents: Certain modified vegetable oils and their derivatives can be used as environmentally friendly solvents. They can not only dissolve paraffin wax but also are easily biodegradable, reducing the long-term impact on the environment.

[0033] 4. Acid-base solutions Weak acid or weak base solutions: Sometimes, acidic or alkaline solutions of a certain concentration are used to change the pH value of the production fluid, thereby destroying the wax structure and promoting its dissolution. However, this method requires careful operation to avoid corroding equipment or affecting other components.

[0034] The exhaust mechanism allows air to circulate and expels the gas in the production fluid, avoiding the formation of bubbles or a high-pressure environment. The exhaust pipe 407 and the blocking sleeve 408 work together to prevent liquid overflow, while ensuring the smooth discharge of gas and maintaining the stable operation of the system. The heating mechanism further reduces the viscosity of the production fluid and promotes the complete dissolution of the residual wax. The heater 403 and the heating pipe 402 work together to provide the necessary heat. The high-temperature resistant ceramic tank body 401 not only protects the components in the heating chamber from high-temperature damage but also provides good heat insulation, ensuring efficient and energy-saving heating. The second upper plate 405 realizes the transportation of the downhole production fluid. The treated clean production fluid flows out of the heating chamber 4 through the second upper plate 405 and is finally transported back to the oil well or other storage facilities through the outlet at the lower end.

[0035] For details, please refer to Figures 1-8 The crushing component includes a rectangular plate 2071, a polished rod 2072, a crushing frame 2074, a spring 2073, a threaded rod 2075, and a rectangular opening 2076. The rectangular plate 2071 is fixedly connected to the circumferential surface of the connecting rod 207. The polished rod 2072 is fixedly connected to the side end of the connecting rod 207. The crushing frame 2074 is fixedly connected to the side end of the polished rod 2072. The spring 2073 is sleeved on the circumferential surface of the polished rod 2072. The threaded rod 2075 is threadedly connected between the rectangular plate 2071 and the crushing frame 2074 through bolts. The rectangular opening 2076 is opened at the side end of the crushing frame 2074. The driving component is arranged on the upper cover 101 to drive the crushing mechanism.

[0036] In this embodiment: The rectangular plate 2071, as part of the crushing process, initially impacts and crushes large impurities entering the crushing chamber 2 through its edges. It also serves to guide the material, ensuring that the impurities can smoothly enter the subsequent processing stage. The polished rod 2072 not only acts as a guiding element to ensure that the crushing frame 2074 moves along a predetermined path but also provides a mounting position for the spring 2073. The presence of the polished rod helps reduce wear and improve the stability of the system. The crushing frame 2074 is one of the core components directly involved in crushing. It is internally provided with multiple crushing teeth or cutting edges for further pulverizing the impurities that have been initially processed by the rectangular plate 2071. The design of the crushing frame allows it to float up and down along the polished rod 2072 to accommodate impurities of different sizes. The spring 2073 provides elastic support, allowing the crushing frame 2074 to have a certain displacement space when encountering greater resistance, thereby protecting the entire crushing mechanism from excessive impact forces and helping to return to the initial position to continue working. This elastic design can also improve the crushing efficiency because the crushing frame can quickly reset after each impact to prepare for the next crushing action. The threaded rod 2075 not only serves as a connecting component but also allows fine-tuning of the position of the crushing frame 2074 by adjusting the thread to accommodate impurities of different sizes and hardnesses and optimize the crushing effect. In addition, the threaded connection method facilitates disassembly and maintenance. The rectangular opening 2076 provides a passage for the impurities to enter and exit, ensuring smooth material flow during the crushing process and avoiding blockage problems. At the same time, the design of the opening also facilitates cleaning and inspection. The driving component is responsible for providing power to the entire crushing mechanism. By driving the connecting column 204 to rotate, the crushing auger 205 and the above-mentioned crushing components cooperate to achieve efficient crushing processing.

[0037] Specifically, please refer to Figures 1-8 , the driving assembly includes a mounting base 103 and a motor 104. The mounting base 103 is fixedly connected to the upper end of the upper cover 101, the motor 104 is fixedly connected to the side end of the mounting base 103, and the output end of the motor 104 is connected to the connecting column 204.

[0038] In this embodiment: The mounting base 103 serves as the support platform for the motor 104, ensuring the stable installation of the motor. It not only provides mechanical support but also ensures the coaxiality between the motor output shaft and the connecting column 204 through position setting, reducing vibration and wear during operation. The motor 104 is the power source of the entire crushing mechanism, responsible for driving the crushing auger 205 and its attached crushing components such as the rectangular plate 2071, the polished rod 2072, and the crushing frame 2074 to rotate. When the motor 104 is started, its output end drives the connecting column 204 to rotate, thereby causing the crushing auger 205 and the crushing components to start operating. The rotational movement of the crushing auger 205 guides the impurities in the production liquid to the crushing components. After the initial impact by the rectangular plate 2071, they enter the crushing frame 2074 for further crushing into small particles. The presence of the spring 2073 allows the crushing frame 2074 to have a certain displacement space when encountering greater resistance, thus protecting the system from excessive impact forces and quickly resetting after crushing to continue working. In addition, the motor 104 can be adjusted in speed through the controller to adapt to different crushing tasks. For example, when dealing with harder impurities, the rotation speed can be appropriately reduced to increase the crushing force; while when dealing with softer impurities, the rotation speed can be increased to accelerate the processing speed. Such flexibility helps to optimize the crushing effect and extend the service life of the equipment.

[0039] Specifically, please refer to Figures 1-8 , the wax melting mechanism includes a wax melting chamber 3, a mounting frame 301, a funnel 302, a chemical solvent injection pipe 303, and a chemical solvent inlet pipe 304. The wax melting chamber 3 is fixedly connected to the lower end of the crushing chamber 2, the mounting frame 301 is fixedly connected to the upper end of the wax melting chamber 3, the funnel 302 is fixedly connected to the lower end of the mounting frame 301, the chemical solvent injection pipe 303 is fixedly connected to the funnel 302 and penetrates through the funnel 302 and extends into the wax melting chamber 3, the chemical solvent inlet pipe 304 is fixedly connected to the side end of the chemical solvent injection pipe 303, the chemical solvent inlet pipe 304 is fixedly connected to the upper cover 101, and the chemical solvent inlet pipe 304 is connected to the chemical solvent injection pipe 303.

[0040] In this embodiment: The wax melting chamber 3 serves as the main place for the wax melting process, and the wax melting chamber 3 provides a sufficient mixing space for the chemical solvent and the production liquid. The installation frame 301 is used to support and fix other components, such as the funnel 302 and the chemical solvent injection pipe 303. The funnel 302 smoothly guides the production liquid after crushing treatment into the wax melting chamber 3, avoiding unnecessary wear or blockage caused by the direct impact of the material on the bottom of the wax melting chamber. In cooperation with the chemical solvent injection pipe 303, the funnel 302 can also help to evenly disperse the chemical solvent, ensuring sufficient mixing of the solvent and the production liquid. The chemical solvent injection pipe 303 is responsible for evenly spraying the chemical solvent transported from the chemical solvent inlet pipe 304 onto the surface of the production liquid in the wax melting chamber 3. The design of the injection pipe usually includes multiple small holes or nozzles to achieve a wider coverage area and better spraying effect. The injection angle and speed can be adjusted according to the actual situation to ensure the optimal mixing ratio of the solvent and the production liquid, thereby accelerating the wax dissolution process. The chemical solvent inlet pipe 304 is the key channel for transporting the chemical solvent to the wax melting chamber 3.

[0041] For details, please refer to Figures 1-8 , the exhaust mechanism includes an exhaust chamber 406, an exhaust pipe 407, and a blocking sleeve 408. The exhaust chamber 406 is fixedly connected to the lower end of the wax melting chamber 3. The exhaust pipe 407 is connected to the side end of the exhaust chamber 406, and the exhaust pipe 407 penetrates through the exhaust chamber 406 and extends inward. The lower end of the exhaust pipe 407 penetrates through the lower cover 102 and extends outward. The blocking sleeve 408 is movably clamped in the exhaust chamber 406, and the length of the exhaust chamber 406 is greater than the position where the exhaust pipe 407 is located.

[0042] In this embodiment: The wax melting chamber 3 serves as the main place for the wax melting process, and the wax melting chamber 3 provides a sufficient space for the chemical solvent and the production liquid to be fully mixed. The mounting frame 301 is used to support and fix other components, such as the funnel 302 and the chemical solvent injection pipe 303. The funnel 302 smoothly guides the production liquid after being crushed into the wax melting chamber 3, avoiding unnecessary wear or blockage caused by the material directly impacting the bottom of the wax melting chamber. In cooperation with the chemical solvent injection pipe 303, the funnel 302 can also help to evenly disperse the chemical solvent, ensuring the full mixing of the solvent and the production liquid. The chemical solvent injection pipe 303 is responsible for evenly spraying the chemical solvent transported from the chemical solvent inlet pipe 304 onto the surface of the production liquid in the wax melting chamber 3. The design of the injection pipe usually includes multiple small holes or nozzles to achieve a wider coverage area and better spraying effect. The injection angle and speed can be adjusted according to the actual situation to ensure the optimal mixing ratio of the solvent and the production liquid, thereby accelerating the wax dissolution process. The chemical solvent inlet pipe 304 is the key channel for transporting the chemical solvent into the wax melting chamber 3. When wax melting treatment is required, an appropriate amount of chemical solvent is injected into the chemical solvent injection pipe 303 through the chemical solvent inlet pipe 304. The solvent is evenly sprayed onto the surface of the production liquid in the wax melting chamber 3 through the small holes or nozzles of the injection pipe. At this time, the production liquid that has been crushed flows into the wax melting chamber 3 through the funnel 302 and is fully mixed with the sprayed chemical solvent. The action of the solvent destroys the molecular structure of the wax and gradually dissolves it in the production liquid.

[0043] For details, please refer to Figures 1-8 , the heating mechanism includes a heating chamber 4, a high-temperature resistant ceramic tank body 401, a heating pipe 402 and a second upper plate 405. The heating chamber 4 is connected to the lower end of the wax melting chamber 3 through a flange. The high-temperature resistant ceramic tank body 401 is sleeved and connected inside the heating chamber 4. The heating pipe 402 is connected between the heating chamber 4 and the high-temperature resistant ceramic tank body 401. The second upper plate 405 is connected to the upper end of the heating chamber 4 by bolt threading. The upper end of the second upper plate 405 is connected to the exhaust mechanism.

[0044] In this embodiment: The heating chamber 4 provides a heating space for the production liquid, ensuring that heat can be evenly transferred to the liquid. The flange connection method not only ensures the sealing between the heating chamber 4 and the wax melting chamber 3, but also facilitates disassembly and maintenance. The high-temperature resistant ceramic tank body 401 can withstand high-temperature environments, protecting the heating tube 402 and other components inside the heating chamber from damage. The ceramic material has good heat preservation performance, reducing heat loss, improving heating efficiency, and ensuring energy-saving and high-efficiency heating processes. The high-temperature resistant ceramic tank body 401 usually has excellent chemical stability and will not react with the components in the production liquid, avoiding secondary pollution. The heating tube 402 is the main heating element, responsible for converting electrical energy into heat energy to directly heat the production liquid. The heating tubes 402 are distributed at different positions inside the heating chamber 4 to ensure that heat can be evenly transferred to the entire production liquid, avoiding problems such as local overheating or uneven heating. It is connected to the upper end of the heating chamber 4 through bolts and threads, and its upper end is connected to the exhaust mechanism. The second upper plate 405 plays a role in sealing the heating chamber 4, preventing heat dissipation and liquid leakage. At the same time, it also provides an installation platform for other components such as the exhaust mechanism. The upper end of the second upper plate 405 is connected to the exhaust mechanism, ensuring that the gas generated during the heating process can be discharged smoothly, maintaining the pressure balance of the system. When the production liquid flows from the wax melting chamber 3 into the heating chamber 4, the heating tube 402 starts to work, converting electrical energy into heat energy to directly heat the production liquid. The high-temperature resistant ceramic tank body 401 not only protects the heating tube 402, but also provides good heat preservation effect, ensuring the effective utilization of heat. As the temperature rises, the viscosity of the production liquid gradually decreases, and the remaining wax further dissolves, making the liquid cleaner. The gas generated during the heating process is discharged smoothly through the exhaust mechanism, maintaining the stable operation of the system. In addition, as the top cover of the heating chamber 4, the second upper plate 405 not only ensures the sealing of the system, but also provides a stable installation foundation for the exhaust mechanism.

[0045] For details, please refer to Figures 1-8 , the upper end of the second upper plate 405 is connected to the electric heater 403 through bolt threads, and the heater 403 is connected to the heating tube 402.

[0046] In this embodiment: The second upper plate 405 seals the heating chamber 4 to prevent heat dissipation and liquid leakage. The heater 403, as part of the power supply and control system, is responsible for supplying the necessary electrical energy to the heating tube 402 and regulating the heating temperature through the built-in controller. The heater 403 is usually equipped with a temperature sensor and a controller, which can monitor the temperature in the heating chamber in real time and automatically adjust the heating power according to the set value to ensure the safety and efficiency of the heating process. When the heating system is started, the heater 403 converts electrical energy into heat energy through the heating tube 402 to directly heat the production liquid. The high-temperature resistant ceramic tank body 401 not only protects the heating tube 402 but also provides good heat insulation effect to ensure the effective utilization of heat. As the temperature rises, the viscosity of the production liquid gradually decreases, and the residual wax further dissolves, making the liquid cleaner. The gas generated during the heating process is discharged smoothly through the exhaust mechanism to maintain the pressure balance of the system. In addition, the temperature sensor on the heater 403 monitors the temperature change in the heating chamber in real time and feeds the data back to the controller. If the temperature exceeds the preset value, the controller will automatically reduce the heating power; otherwise, it will increase the power to maintain the best heating effect.

[0047] For details, please refer to Figures 1-8 At the upper end of the second upper plate 405, a controller 404 is connected by bolt threads, and the controller 404 is connected to the heater 403.

[0048] In this embodiment: The controller 404 receives data from the temperature of the device and automatically adjusts the output power of the heater 403 according to the preset parameters to ensure that the temperature in the heating chamber 4 is stable within the set range. When the heating system is started, the controller 404 controls the heater 403 according to the preset program, and the latter converts electrical energy into heat energy through the heating tube 402 to directly heat the production liquid. The high-temperature resistant ceramic tank body 401 not only protects the heating tube 402 but also provides good heat insulation effect to ensure the effective utilization of heat. As the temperature rises, the viscosity of the production liquid gradually decreases, and the residual wax further dissolves, making the liquid cleaner. The gas generated during the heating process is discharged smoothly through the exhaust mechanism to maintain the pressure balance of the system.

[0049] For details, please refer to Figures 1-8 The diameters of the protective outer cylinder 1, the upper cover 101, and the lower cover 102 are equal, and the thickness of the protective outer cylinder 1 is 5 cm.

[0050] In this embodiment: Since the diameters of the protective outer cylinder 1, the upper cover 101, and the lower cover 102 are equal, the assembly of the entire system is simpler, reducing installation errors and also facilitating daily inspection and maintenance. The 5-cm-thick protective outer cylinder 1 provides sufficient mechanical strength to withstand external pressure and impact, ensuring the durability and reliability of the equipment in complex working environments. Through the bolt-thread connection method, the tight sealing between the upper cover 101 and the lower cover 102 and the protective outer cylinder 1 is ensured, preventing external impurities from entering and internal liquid leakage, and maintaining the normal operation of the system.

[0051] The working principle and usage process of the present invention: First, inject the production liquid to be processed into the crushing chamber 2 through the liquid inlet pipe 202, ensuring that the liquid volume is appropriate, neither overflowing nor affecting the subsequent treatment effect. If necessary, introduce an appropriate amount of gas into the system through the gas inlet pipe 203 to assist in stirring or adjusting the internal pressure. Start the motor 104 to drive the crushing auger 205 to rotate and crush the impurities in the production liquid entering the crushing chamber 2. During the crushing process, crushing components such as the rectangular plate 2071, the polished rod 2072, and the spring 2073 work together to ensure that large impurities are effectively crushed into small particles. The crushed production liquid flows into the wax melting chamber 3. At this time, inject an appropriate amount of chemical solvent into the wax melting chamber 3 through the chemical solvent inlet pipe 304, and use the funnel 302 and the chemical solvent spraying pipe 303 to evenly spray the solvent on the surface of the production liquid. The chemical solvent in the wax melting chamber 3 is fully mixed with the production liquid to dissolve the wax components therein. This process can be accelerated at a set temperature to improve efficiency. The production liquid after the wax melting treatment enters the exhaust chamber 406. During this process, the exhaust pipe 407 allows air to circulate and discharges the gas in the production liquid, avoiding the formation of bubbles or a high-pressure environment and blocking the liquid from overflowing from the exhaust pipe 407. At the same time, it ensures the smooth discharge of gas and maintains the stable operation of the system. After the exhaust treatment is completed, the production liquid continues to flow downward to the heating chamber 4. The heater 403 and the heating pipe 402 work together to heat the production liquid, further reducing the viscosity and promoting the complete melting of the residual wax. The high-temperature resistant ceramic tank body 401 protects the components in the heating chamber 4 from high-temperature damage and provides a good heat preservation effect, ensuring efficient and energy-saving heating. The cleaned production liquid after the above treatment flows out of the heating chamber 4 through the second upper plate 405 connected by a flange and is finally transported back to the oil well or other storage facilities through the outlet at the lower end. Through the above steps, this oil well scale and wax prevention processor can effectively remove impurities and wax components in the production liquid, ensure the smooth and efficient operation of the oil well. The entire treatment process has a high degree of automation, is easy to operate, and is convenient to maintain, meeting the scale and wax prevention requirements of various oil wells.
