Description

Technical Field

[0001] This utility model belongs to the field of multiphase flow detection technology, and in particular relates to an experimental platform for multiphase flow detection of oil and natural gas with flow regulation function. Background Technology

[0002] Oil and natural gas are vital global energy resources, and multiphase flow phenomena are widespread during their extraction, transportation, and processing. Accurate detection and measurement of parameters such as the flow rate and composition of each phase in multiphase flow are crucial for improving oil and gas recovery, optimizing production processes, and reducing costs. As oil and gas field development expands into deep-sea areas and complex geological conditions, higher demands are placed on the accuracy, reliability, and adaptability of multiphase flow detection technologies, necessitating simulation experiments and technological development on experimental platforms.

[0003] In actual oil and gas production, the flow rate of multiphase flow varies with factors such as production time and extraction conditions. Therefore, the experimental setup needs to have flow rate adjustment capabilities to simulate multiphase flow under different flow rate conditions. By adjusting the flow rate, the characteristics of multiphase flow under different flow velocities and flow patterns can be studied, and the accuracy and stability of the detection technology within different flow ranges can be verified, providing more comprehensive and reliable data support for multiphase flow detection in actual production.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] like Figures 1-2 As shown, the oil and gas multiphase flow detection test bench with flow regulation function includes a base shell 1, an opening at one end of the base shell 1, a sealing cover 2 connected to the opening by a fixing bolt, and a flow control component set on the sealing cover 2. The flow control component is used to realize the flow regulation of the feed. A stirring component is provided inside the base shell 1, and a discharge port 3 is provided at the other end of the base shell 1.

[0026] The discharge port 3 is equipped with a water outlet valve, which is connected to the collection device.

[0027] like Figures 2-3As shown in Figure 4-5, the flow control assembly includes a three-way pipe 4, an adjusting rod 5, a pressure plate 6, and a slider 7. The three-way pipe 4 has an A end, a B end, and a C end. The A end of the three-way pipe 4 is inserted into the sealing cap 2. The adjusting rod 5 is threaded to the B end of the three-way pipe 4. The pressure plate 6 is fixed to the lower end of the adjusting rod 5. The slider 7 is slidably disposed inside the three-way pipe 4. The slider 7 has a through hole 8 that matches the A end of the three-way pipe 4. The C end of the three-way pipe 4 is connected to an external storage tank. The inner side of the C end of the three-way pipe 4 has a Venturi tube structure. A spring 9 is provided between the pressure plate 6 and the slider 7. A pressure sensor 10 is provided at the upper end of the slider 7.

[0028] The three-way pipe 4 is provided with three sets. The A end of the three-way pipe is inserted at intervals on the outside of the sealing cover 2, and the interior of the base shell 1 is connected to the interior of the three-way pipe through the A end of the three-way pipe. The spring 9 is set inside the three-way pipe 4. One end of the spring 9 is in contact with the lower end of the pressure plate 6, and the other end of the spring 9 is in contact with the upper end of the pressure sensor 10. The pressure sensor 10 is used to monitor the pushing force of the raw material on the slider 7. The pressure plate 6 is positioned by adjusting the thread structure of the rod 5 and the B end of the three-way pipe 4, which changes the elastic deformation of the spring 9. When the pressure of the raw material pushes the slider 7 to the point where the through hole 8 is connected to the A end of the three-way pipe 4, the raw material enters the base shell 1. The pressure control before the raw material enters the base shell 1 is changed, thereby achieving the effect of regulating the flow rate of the raw material. The pressure sensor 10 transmits the specific data of the fluid pressure to the microprocessor and the display controller to realize the data display of the flow rate.

The end of the power roller 11 that passes through the base shell 1 is poweredly connected to the power end of the rotary motor 13. The rotary motor 13 is fixed to the outside of the base shell 1. The stirrer 12 is fixed to the power roller 11. A concentration sensor is provided on the inside of the base shell 1.

[0030] The base shell 1 has a microprocessor on its outer side. One end of the microprocessor is electrically connected to the display controller via a wire. The pressure sensor 10 and the concentration sensor are also electrically connected to the microprocessor via wires. The rotary motor 13 is electrically connected to the microprocessor via wires. The stirrers 12 are arranged in a grid pattern, and there are three sets of stirrers 12. The stirrers 12 are spaced apart along the central axis of the power roller 11. The raw materials are injected into the base shell 1 after being pressurized by the flow control component, so that the three-phase fluids are initially mixed. Then, the concentration of the three-phase fluids in the base shell 1 is monitored by the concentration sensor inside the base shell 1. The microprocessor controls the rotary motor 13 to drive the stirrers 12 to stir and mix the three-phase fluids. The stirring speed is adjusted by the display controller according to different experimental requirements to ensure that the multiphase flow is mixed evenly.
