Description
Technical Field
[0001] This application relates to the field of oil extraction equipment technology, and in particular to intelligent adjustable nozzles for ultra-high pressure oil wells. Background Technology
[0002] In the oil extraction industry, the efficiency and stability of oil wells have always been key concerns. With continuous technological advancements, the extraction technology for ultra-high pressure oil wells is also constantly evolving. Ultra-high pressure oil wells operate in complex environments with extremely high pressures. Precisely controlling well output and pressure is crucial for ensuring safe and stable production and improving oil extraction efficiency. Effective well control technologies can reduce extraction costs, minimize resource waste, and positively contribute to the sustainable development of the entire oil industry.
[0003] In traditional ultra-high pressure oil well production, fixed nozzles or simple manually adjustable nozzles were typically used. Fixed nozzles had pre-set oil output and pressure parameters based on experience. Manually adjustable nozzles required periodic on-site visits to the well to manually rotate the adjustment knob based on observation and experience, thus regulating oil output and pressure. Some nozzles used mechanical feedback mechanisms, employing springs, pistons, or other mechanical structures to automatically adjust the nozzle opening based on changes in well pressure; however, this method had limited adjustment precision.
[0004] Existing technologies have significant shortcomings in regulating oil production and pressure in ultra-high pressure oil wells. Fixed nozzles cannot be adjusted in real time according to the actual operating conditions of the well. When the well pressure or oil production changes, they cannot respond promptly, which can easily lead to unstable well production and even safety accidents. Manually adjusting nozzles is not only inefficient but also requires a large amount of manpower, and the accuracy of manual adjustment is difficult to guarantee, greatly affected by the operator's experience and skill level. Mechanical feedback nozzles have low adjustment accuracy and cannot meet the precise control requirements of ultra-high pressure oil wells for oil production and pressure. Utility Model Content
[0005] To ensure efficient and stable extraction processes, this utility model provides an intelligent adjustable nozzle for ultra-high pressure oil wells.
[0006] The intelligent adjustable nozzle for ultra-high pressure oil wells provided by this utility model adopts the following technical solution: An intelligent adjustable nozzle for ultra-high pressure oil wells includes a valve body assembly and a control assembly. The valve body assembly includes a cavity structure with a first flow channel and a second flow channel, as well as an output flow channel. A rotatably mounted valve core is disposed within the cavity structure. The valve core has several guide holes of different diameters distributed along the axial direction of the valve core. Several oil passage holes are provided on the side wall of the cavity structure. The cavity structure is connected to the output flow channel through one of the guide holes and one of the oil passage holes. The control assembly includes an intelligent controller and a transmission rod. The intelligent controller is connected to one end of the transmission rod, and the other end of the transmission rod passes through the cavity structure and is connected to the valve core. A first pressure gauge and a flow meter are connected to the input end of the first flow channel, and a second pressure gauge is connected to the output flow channel. The first pressure gauge, the flow meter, and the second pressure gauge are all electrically connected to the intelligent controller, and the intelligent controller is communicatively connected to a display.
[0007] By adopting the above technical solution, the arrangement of the first flow channel, the second flow channel, and the output flow channel enables the oil to flow orderly within the intelligent adjustable nozzle for ultra-high pressure oil wells. Several guide holes distributed along the axial direction on the valve core and several oil passage holes on the sidewall of the cavity structure, with the cavity structure connecting to the output flow channel only through one guide hole and one oil passage hole at a time, allow for oil flow and regulation. The first pressure gauge, flow meter, and second pressure gauge transmit oil pressure and flow data to the intelligent controller. The intelligent controller can then control the valve core rotation via a transmission rod based on this data, thereby regulating the oil flow. Simultaneously, the display connected to the intelligent controller displays relevant data for easy observation by the operator. Furthermore, the coordinated arrangement of channels and holes allows the nozzle to effectively regulate and control the oil to adapt to different operating conditions.
[0008] Preferably, there is an included angle between the axes of any two of the guide holes.
[0009] By adopting the above technical solutions, the flow path of oil between different guide holes becomes more complex and variable, enabling more precise regulation of oil flow and pressure, and enhancing the control capability of the nozzle.
[0010] Preferably, the plurality of oil passages are spaced apart along the axial direction of the cavity structure.
[0011] By adopting the above technical solutions, the flow path of the oil in the cavity structure becomes more diverse, which can adapt to different flow and pressure regulation requirements, and facilitates the precise flow control of the oil when the valve core rotates and cooperates with different guide holes.
[0012] Preferably, each of the guide holes is provided with a corresponding oil passage hole, and the diameter of the oil passage hole is larger than the diameter of the corresponding guide channel.
[0013] By adopting the above technical solution, it is ensured that the oil in each guide hole can flow in conjunction with the corresponding oil passage hole, and the larger diameter of the oil passage hole can reduce the oil flow resistance and improve the oil flow efficiency.
[0014] Preferably, an expansion-type turbulent buffer cavity is formed at the intersection of the first flow channel and the second flow channel.
[0015] By adopting the above technical solutions, the fluid can transition more stably, reducing pressure fluctuations and energy loss.
[0016] Preferably, the first flow channel and the second flow channel are arranged perpendicularly.
[0017] By adopting the above technical solution, the intelligent adjustable nozzle for ultra-high pressure oil wells is designed with an angle structure, which makes matching with the wellhead simple and quick, and can meet the installation and use of wellhead wellheads of different models.
[0018] In summary, this utility model has the following beneficial effects: 1. The design of the first flow channel, second flow channel, and output flow channel allows for the orderly flow of oil within the intelligent adjustable nozzle of the ultra-high pressure oil well. Several guide holes distributed along the axial direction on the valve core and several oil passage holes on the sidewall of the cavity structure, with the cavity structure connecting to the output flow channel only through one guide hole and one oil passage hole at a time, enable oil flow and regulation. The first pressure gauge and flow meter at the input end of the first flow channel, and the second pressure gauge connected to the output flow channel, transmit oil pressure and flow data to the intelligent controller. The intelligent controller uses this data to control the valve core rotation via a transmission rod, connecting different guide holes and oil passage holes to the output flow channel. This allows for real-time and precise adjustment of the oil output and pressure of the ultra-high pressure oil well, preventing instability in well production and safety accidents. Simultaneously, the display connected to the intelligent controller shows relevant data for easy observation by operators.

[0026] Intelligent adjustable nozzles for ultra-high pressure oil wells, refer to Figure 1 and Figure 2The system includes a valve body assembly 1 and a control assembly 4. The valve body assembly 1 includes a cavity structure 11 and an output flow channel 12, which communicates with the cavity structure 11. A rotatable valve core 2 is located within the cavity structure 11, and the valve core 2 has several guide holes 21 of different diameters. Several oil passage holes 3 are located on the side wall of the cavity structure 11. The control assembly 4 includes an intelligent controller 41 and a transmission rod 42. One end of the transmission rod 42 is connected to the intelligent controller 41, and the other end passes through the cavity structure 11 and is fixedly connected to the valve core 2. By controlling the rotation of the valve core 2, the flow channel of the oil is changed, thereby achieving precise regulation of the oil output and pressure of the ultra-high pressure oil well, improving the stability and safety of oil well production. A first pressure gauge 5 and a flow meter 6 are connected to the input end of the cavity structure 11, and a second pressure gauge 7 is connected to the output flow channel 12. The first pressure gauge 5, flow meter 6, and second pressure gauge 7 are all electrically connected to the intelligent controller 41, which is communicatively connected to a display.
[0027] The first pressure gauge 5, flow meter 6, and second pressure gauge 7 can transmit data such as oil pressure and flow rate to the intelligent controller 41. The intelligent controller 41 can control the valve core 2 to rotate through the transmission rod 42 based on these data, so that different guide holes 21 and oil passage holes 3 are connected to the output flow channel 12. This can adjust the oil output and pressure of the ultra-high pressure oil well in real time and accurately, avoiding unstable oil well production and safety accidents.
[0028] Reference Figure 1 The cavity structure 11 is provided with a first flow channel 111 and a second flow channel 112 to guide the oil into the cavity structure 11. The intersection of the first flow channel 111 and the second flow channel 112 forms an expanding turbulent buffer cavity 113, which functions to create turbulence in the oil at the intersection, thereby buffering and mixing the oil and reducing the impact and fluctuation of the oil. The first flow channel 111 and the second flow channel 112 are arranged perpendicularly, which allows for better mixing of the oil at the intersection and further optimizes the flow characteristics of the oil.
[0029] Reference Figure 1 The valve core 2 can be a cylindrical structure, and the guide holes 21 are spaced apart along the axis of the valve core 2, with the axis of the guide holes 21 perpendicular to the axis of the valve core 2. The guide holes 21 are circular through holes, and their function is to cooperate with the oil passage holes 3 on the side wall of the cavity structure 11 when the valve core 2 rotates to form different oil flow channels.
[0030] Reference Figure 1 and Figure 2 The number of guide holes 21 and the number of oil passage holes 3 can be set according to the actual situation. In this embodiment, there are three guide holes 21 and three oil passage holes 3. The guide holes 21 and the oil passage holes 3 correspond one-to-one, and the diameter of the oil passage hole 3 is larger than the diameter of the corresponding guide hole 21.
[0031] The oil in each guide hole 21 can flow with the corresponding oil passage hole 3, and the larger diameter of the oil passage hole 3 can reduce the oil flow resistance and improve the oil flow efficiency.
[0032] Reference Figure 1 and Figure 2 There is an included angle between the axes of any two guide holes 21. Multiple oil passage holes 3 are distributed at intervals along the axis of the cavity structure 11, and the axes of the multiple oil passage holes 3 are all located on the same vertical plane.
[0033] The flow path of the oil in the cavity structure 11 is more diverse, which can adapt to different flow and pressure regulation requirements, and facilitates the precise flow control of the oil when the valve core 2 rotates and cooperates with different guide holes 21.
[0034] Reference Figure 1 The intelligent controller 41 can be a microprocessor-based control device with data processing and control functions. The intelligent controller 41 is fixedly connected to one end of the transmission rod 42, and the other end of the transmission rod 42 passes through the cavity structure 11 and is fixedly connected to the valve core 2. The transmission rod 42 converts the control signal of the intelligent controller 41 into the rotational action of the valve core 2.
[0035] Reference Figure 1 The first pressure gauge 5 measures the input pressure of the oil well, and the flow meter 6 measures the flow rate of the oil. The second pressure gauge 7 measures the pressure of the oil after adjustment. The first pressure gauge 5, flow meter 6, and second pressure gauge 7 are all electrically connected to the intelligent controller 41, and they transmit the measured data to the intelligent controller 41. The intelligent controller 41 is connected to a display, which can be an LCD screen, to display data such as the oil well's pressure and flow rate, facilitating real-time monitoring of the oil well's operating status by operators.
[0036] The operating principle of this application is as follows: Pressure and flow data of the oil well are acquired in real time through the first pressure gauge 5, flow meter 6, and second pressure gauge 7, and this data is transmitted to the intelligent controller 41. The intelligent controller 41 calculates the required flow and pressure values based on preset parameters and real-time data. Then, it controls the valve core 2 to rotate via the transmission rod 42, aligning the appropriate guide hole 21 with the oil passage hole 3, thereby achieving precise adjustment of the oil well's output and pressure. The display shows the oil well's operating status in real time, facilitating monitoring and management by operators. This intelligent adjustable nozzle overcomes the problems of fixed nozzles that cannot be adjusted in real time, the low efficiency and insufficient precision of manual nozzle adjustment, and the limited adjustment precision of mechanical feedback nozzles in existing technologies. It improves the stability and safety of ultra-high pressure oil well extraction and reduces extraction costs.
[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
