Description

Technical Field

[0001] This invention relates to the field of instruments for testing the suspension performance of proppant, and more particularly to instruments for testing the suspension performance of self-suspended proppant. Background Technology

[0002] In deep oil and gas well development, hydraulic fracturing is one of the main measures to increase well production in the oil and gas industry. The physicochemical properties of proppant directly affect its production enhancement effect. By mixing proppant into fracturing fluid and injecting it into fractures in deep rock, the proppant forms a filler or support at the fracture site to maintain and open the fracture, supporting the fracture and creating a highly permeable crude oil flow channel, ensuring smooth crude oil passage and maximizing the well's production potential.

[0003] Imparting the property of existing proppants to float in water without immediately sinking allows them to suspend directly in water, forming self-suspended proppants. This eliminates the need for thickeners to create a more viscoelastic fracturing fluid, representing a promising area of ​​development in fracturing proppant technology. The hydratable molecules on the surface of self-suspended proppants swell rapidly upon contact with water, forming a stable hydration layer around the proppant core. This hydration layer reduces the proppant's density in water, increasing lubricity between proppant molecules. Simultaneously, a small number of organic molecules on the proppant surface extend into the aqueous solution, increasing the water's viscosity. This synergistic effect allows self-suspended proppants to easily suspend in clear water for extended periods without the aid of thickeners.

[0004] A test instrument for the suspension performance of self-suspended proppant, disclosed in CN106248537B, includes a container with an open top. A gas collecting plate is located at the bottom of the container and contains a hollow cavity. A vent is located on the upper surface of the gas collecting plate, communicating with the hollow cavity. A vent pipe is also located on the gas collecting plate and communicates with the hollow cavity. When self-suspended proppant particles come into contact with a large number of fine, uniform air bubbles in clear water, the bubbles adsorb onto the surface of the proppant particles, increasing the volume of water occupied by the proppant particles. This increases the buoyancy of the self-suspended proppant particles, making the suspension state of the self-suspended proppant particles more closely resemble their actual usage state during testing.

[0005] The above technical solution makes it difficult to thoroughly clean the components after testing, which can easily lead to residues and affect the accuracy of subsequent testing. Therefore, improvements are needed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-suspending proppant suspension performance testing instrument.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A self-suspension proppant suspension performance testing instrument includes a mounting base, on which a mounting frame is fixed. A collar assembly is detachably connected to the upper end of the mounting frame. A conical sealing gasket assembly is detachably connected inside the collar assembly. An aeration plate assembly is fixed to the upper end of the conical sealing gasket assembly. An aeration mechanism is provided at the lower end of the aeration plate assembly. A measuring tube is provided through the collar assembly, and a clamping mechanism is provided inside the collar assembly. The clamping mechanism abuts against the measuring tube, and the lower end of the measuring tube is sealed to the conical sealing gasket assembly. The mounting frame houses a drive mechanism, which includes a timing belt assembly, a crossbar, and a connecting pipe. The connecting pipe is fixedly connected to the conical sealing gasket assembly, and the aeration mechanism is connected to the connecting pipe. A transmission mechanism is mounted on one side of the upper end of the mounting base, and the timing belt assembly is connected to the transmission mechanism. A stirring element is detachably connected to the transmission mechanism, and the lower end of the stirring element extends into the measuring pipe. A positioning mechanism is installed at one end of the crossbar, and the positioning mechanism is connected to the mounting bracket. The connecting pipe is rotatably sleeved on the end of the crossbar away from the positioning mechanism.

[0008] Compared with the prior art, this application achieves full contact between air bubbles and self-suspended proppant particles. Furthermore, by stirring and rotating the measuring tube, the reaction time between the self-suspended proppant particles and water can be shortened, and the flow effect can be simulated to achieve the effect of testing the deposition of suspended particles as needed. In addition, the components in this application can be quickly disassembled for thorough cleaning, avoiding residues and ensuring the accuracy of subsequent testing.

[0009] Preferably, the aeration mechanism includes an aeration component mounted on a mounting base, the aeration component being disposed through the mounting frame, one end of the aeration component being connected to a rotatable connecting pipe, and one end of the rotatable connecting pipe being connected to an aeration pipe with a one-way valve.

[0010] Furthermore, the corresponding water is injected into the measuring pipe fitting. The aeration component is the air supply component. In actual operation, the air inlet pipe of the aeration component is equipped with a filter and purification component, which can effectively improve the air quality. Moreover, the air enters the aeration pipe with a one-way valve through the aeration component and the rotating connecting pipe fitting. When the one-way valve on the aeration pipe with a one-way valve is subjected to the air pressure in the rotating connecting pipe fitting, the gas can be opened so that the gas can enter the aeration plate assembly through the rotating connecting pipe fitting and the aeration pipe with a one-way valve to effectively form bubbles and enter the measuring pipe fitting. The operation of the aeration components can be controlled by the control cabinet assembly, so as to control the amount of air bubbles in the pipe fittings. When the air bubbles are stable, adding self-suspended proppant particles can make the self-suspended proppant particles fully contact the air bubbles, slow down the settling speed, and make it easier for the self-suspended proppant particles to react with the water.

[0011] Preferably, a plurality of mounting grooves are equally spaced on the circumferential sidewall of the collar assembly. A bushing is rotatably fitted on one end of the mounting groove. A telescopic rod assembly is rotatably fitted on the bushing. A spring is fitted on the telescopic rod assembly. The two ends of the spring are respectively fixed to the two ends of the bushing. A locking ball assembly is rotatably fitted on the end of the telescopic rod assembly away from the bushing. One end of the locking ball assembly passes through the mounting groove and extends into the collar assembly. An annular groove is formed at the upper end of the mounting bracket, and the plurality of locking ball assemblies extend into the annular groove.

[0012] Furthermore, during assembly, the mounting bracket and mounting base are fixedly connected. The operator can align the collar assembly with the mounting bracket, and ensure that the end of the collar assembly without the notch faces downwards. This facilitates pressing down the collar assembly, allowing the upper end of the mounting bracket to insert into the collar assembly. The upper end of the mounting bracket will press against the locking ball assembly, which can rotate against the outer wall of the mounting bracket and transmit pressure to the telescopic rod assembly and the spring. The two ends of the spring are fixed to the sleeve end and the telescopic end inside the telescopic rod assembly, respectively. The telescopic end of the telescopic rod assembly can be inserted into the sleeve end of the telescopic rod assembly, causing the spring to retract. When the locking ball assembly aligns with the annular groove, the spring returns to its original shape, allowing the locking ball assembly to insert into the annular groove, thus completing the connection between the collar assembly and the mounting bracket. Meanwhile, the locking ball assembly can rotate relative to the telescopic rod assembly, and the telescopic rod assembly can rotate around its center line, which facilitates the rotation of the collar assembly relative to the mounting bracket.

[0013] Preferably, the conical sealing gasket assembly is sealed and installed inside the collar assembly, and a positioning connecting bolt is provided through the collar assembly, with one end of the positioning connecting bolt threaded into the conical sealing gasket assembly.

[0014] Furthermore, by rotating the positioning bolts, the relative positions between the conical sealing gasket assembly and the collar assembly can be fixed. In actual production and processing, workers can add corresponding sealing components around the conical sealing gasket assembly, which can make it fully contact the inner wall of the collar assembly and fill the gaps through deformation, thus preventing leakage and seepage.

[0015] Preferably, the clamping mechanism includes multiple notches evenly spaced on the inner sidewall of the collar assembly, an abutting shaft is installed on one end sidewall of the notch, an abutting point is abutted on one side of the abutting shaft, and one end of the abutting point abuts against the measuring tube fitting. A movable frame is fixed to one side of the contact point. The lower end of the movable frame is inserted through the notch. The side of the movable frame away from the contact point abuts against the contact shaft. A slide rail is fixed to the top of the movable frame. A lifting rod is slidably installed on the slide rail. An annular cavity is opened in the mounting frame. A circular ring is installed in the annular cavity. The lower ends of multiple lifting rods extend into the annular cavity and are fixedly connected to the circular ring. A screw is threaded onto the collar assembly, and the lower end of the screw is rotatably mounted on the upper end of the ring.

[0016] Furthermore, during use, once the conical sealing gasket assembly is fixed and the collar assembly and mounting bracket are connected, the operator can make the measuring tube fitting and the conical sealing gasket assembly come into contact, and the aeration plate assembly is located inside the measuring tube fitting. The operator can rotate the screw to push the ring down, which in turn drives the lifting rod down. The lifting rod then drives the moving frame down via the slide rail. When the moving frame descends, its inclined inner sidewall comes into contact with the abutment shaft, causing the moving frame to move toward the axis of the collar assembly. This movement of the moving frame causes the abutment point to come into contact with the outer wall of the measuring tube. As the screw continues to rotate, the moving frame causes the abutment point to move downward and inward. Multiple abutment points are evenly spaced and come into contact with the lower end of the measuring tube, allowing the measuring tube to come into full contact with the conical sealing gasket assembly to complete the seal. After the inspection is completed, the staff can rotate the screw to make the screw drive the ring to rise, so that the contact point no longer exerts a downward or inward force on the measuring tube.

[0017] Preferably, the drive mechanism includes a motor assembly mounted on one side wall of the mounting bracket, wherein the lower end of the crossbar is rotatably sleeved with a vertical shaft, and a drive belt assembly is mounted on both the vertical shaft and the connecting pipe. The lower end of the vertical shaft and the end of the output shaft of the motor assembly are both equipped with a contact transmission disc, and the two contact transmission discs abut against each other. An opening is provided on one side of the mounting bracket, and the timing belt assembly is disposed through the opening. One end of the timing belt assembly is connected to the output shaft of the motor assembly.

[0018] Furthermore, the motor assembly is connected to the corresponding power supply components and control cabinet assembly, which can control the rotation speed of the motor assembly. When the collar assembly and the mounting bracket are connected, the two abutting transmission discs can abut against each other. In order to ensure the transmission effect, friction textures or corresponding gears can be set on the opposite side of the two abutting transmission discs to ensure the transmission effect. When the drive disc rotates under the action of the motor assembly, it enables the vertical shaft to drive the drive belt assembly. The operation of the drive belt assembly enables the connecting pipe to rotate, which in turn drives the conical sealing gasket assembly, the aeration plate assembly, and the measuring pipe to rotate. The drive belt assembly consists of two pulleys and a belt fitted on the two pulleys. Both the pulleys and the belt are equipped with teeth. The meshing of the teeth ensures the power transmission effect and facilitates the rotation of the measuring pipe.

[0019] Preferably, the transmission mechanism includes a support frame fixed to one side of the upper end of the mounting base, a transmission shaft assembly rotatably sleeved inside the support frame, the transmission shaft assembly being connected to a synchronous belt assembly, and the transmission shaft assembly being connected to a linkage shaft; A detachable component is installed at the lower end of the linkage shaft, and the detachable component is detachably connected to the stirring component.

[0020] Furthermore, in actual operation, two corresponding pulleys and belt components are installed on the upper end of the support frame. The two pulleys are fixed on the drive shaft assembly and the linkage shaft respectively, and the drive shaft assembly and the linkage shaft can rotate synchronously through the action of the belt. The rotation of the output shaft of the motor assembly enables the synchronous belt assembly to drive the transmission shaft assembly to rotate. The synchronous belt assembly consists of two pulleys and a belt sleeved on the pulleys. The toothed structure enables the transmission shaft assembly to rotate under the action of the motor assembly, thus enabling the linkage shaft to rotate. In actual operation, the detachable component has a detachable locking structure, which allows the upper end of the agitator to be connected to the detachable component, so that the agitator and the detachable component are firmly connected, and the linkage shaft can drive the agitator to rotate, that is, both the agitator and the measuring tube can rotate. During operation, the presence or absence of a stirring component, depending on the actual situation, can simulate the suspension state under flowing conditions by determining whether the self-suspended proppant particles are agitated.

[0021] Preferably, a control cabinet assembly is fixed to one side of the support frame.

[0022] Furthermore, in actual operation, the corresponding circuits and control components of the automation components set in this application are all installed on the control cabinet assembly, and the circuits are equipped with corresponding switching components. The installation and setting methods are conventional technical means in this field, and the operation of the automation components in this application can be controlled through the control cabinet assembly.

[0023] Preferably, the positioning mechanism includes a notch formed on one side wall of the mounting frame, a positioning rod fixed at the bottom of the notch, a positioning block fixed at one end of the crossbar, the positioning block being disposed through the notch, and the positioning rod being disposed through the positioning block.

[0024] Furthermore, when connecting the collar assembly and the mounting bracket, the conical sealing gasket assembly and the collar assembly are fixed, and the positioning block and the notch are aligned, and the positioning rod is inserted into the positioning block so that the vertical shaft and the connecting pipe will not rotate arbitrarily through the action of the notch, the positioning block and the crossbar, ensuring their relative stability. For example, it can fully ensure that the two abutting transmission discs can abut and transmit power. Furthermore, during actual production, the connection point between the vertical shaft and the contact transmission disc can be equipped with an elastic telescopic component, which can adapt to errors during processing and ensure that the two contact transmission discs can fully contact each other.

[0025] Preferably, the movable frame is tilted on the side away from the contact point.

[0026] Furthermore, the downward and inward movement of the moving frame is controlled by the contact between the inclined edge of the moving frame and the contact axis.

[0027] The beneficial effects of this invention are: 1. During operation, the aeration components enable the aeration plate components to quickly spray a large number of uniform and stable bubbles into the water inside the vector pipe, so as to add self-suspended proppant particles inside the vector pipe. The bubbles can slow down the settling speed of the self-suspended proppant particles, making it easier to react with the water and achieve the purpose of accurately detecting the self-suspension status. Simultaneously, the rotation of the agitator and measuring tube can simulate the suspension in flowing water. 2. The connections between components in this application are detachable, which facilitates quick assembly and allows for replacement as needed in case of damage or other issues. Furthermore, after each test, the components can be completely disassembled to avoid residue and ensure the accuracy of the next test. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1-9 The self-suspension proppant suspension performance testing instrument includes a mounting base 1, on which a mounting frame 3 is fixed to ensure the stability of the mounting frame 3 and the overall structural stability. A collar assembly 4 is detachably connected to the upper end of the mounting frame 3. A conical sealing gasket assembly 14 is detachably connected inside the collar assembly 4. An aeration plate assembly 13 is fixed to the upper end of the conical sealing gasket assembly 14, and an aeration mechanism is provided at the lower end of the aeration plate assembly 13. A measuring tube 5 is inserted through the collar assembly 4. The measuring tube 5 is transparent. The tube is made of clear glass and has through-holes at both ends. Scale lines are provided on the tube. The collar assembly 4 has a clamping mechanism that abuts against the measuring tube 5. The lower end of the measuring tube 5 is sealed to the conical sealing gasket assembly 14. Through the clamping mechanism and detachable connection, the connection and sealing between the mounting frame 3, the collar assembly 4, and the measuring tube 5 can be completed. The collar assembly 4 and the measuring tube 5 can be sealed and fixed. The collar assembly 4 can rotate relative to the mounting frame 3 to simulate suspension in flowing water.

[0031] In this embodiment, a drive mechanism is installed inside the mounting frame 3. The drive mechanism is equipped with a synchronous belt assembly 11, a crossbar 28, and a connecting pipe 27. The connecting pipe 27 is fixedly connected to the conical sealing gasket assembly 14. The aeration mechanism and the connecting pipe 27 are connected through each other. A transmission mechanism is installed on one side of the upper end of the mounting base 1. The synchronous belt assembly 11 is connected to the transmission mechanism. A stirring element 6 is detachably connected to the transmission mechanism. The lower end of the stirring element 6 extends into the measuring pipe 5. A positioning mechanism is installed at one end of the crossbar 28. The positioning mechanism is connected to the mounting frame 3. The connecting pipe 27 is rotatably sleeved on the end of the crossbar 28 away from the positioning mechanism. The measuring pipe 5 and the stirring element 6 can be rotated through the drive mechanism and the transmission mechanism. The stirring element 6 is detachably connected, and it can be determined whether to install the stirring element 6 as needed. The structure in this application adopts an assembly type, which can thoroughly clean the components before the next test to avoid residue and ensure the quality of the test.

[0032] In this embodiment, the aeration mechanism includes an aeration component 2 mounted on the mounting base 1. The aeration component 2 is installed through the mounting frame 3. One end of the aeration component 2 is connected to a rotating connecting pipe 16, and one end of the rotating connecting pipe 16 is connected to an aeration pipe 15 with a one-way valve. Water is injected into the measuring pipe 5. The aeration component 2 is an air supply component. In actual operation, a filter and purification component is installed on the air inlet pipe of the aeration component 2, which can effectively improve the air quality. Moreover, the air enters the aeration pipe 15 with a one-way valve through the aeration component 2 and the rotating connecting pipe 16. When the one-way valve on the aeration pipe 15 is subjected to the air pressure in the rotating connecting pipe 16, the gas can be opened so that the gas can enter the aeration plate assembly 13 through the rotating connecting pipe 16 and the aeration pipe 15 with a one-way valve to effectively form bubbles and enter the measuring pipe 5. The operation of the aeration component 2 can be controlled by the control cabinet component 41, so as to control the amount of air bubbles in the measuring pipe 5. When the air bubbles are stable, the addition of self-suspended proppant particles can make the self-suspended proppant particles fully contact the air bubbles, slow down the sinking speed, and make it easier for the self-suspended proppant particles to react with the water.

One end of the locking ball assembly 17 passes through the mounting groove 18 and extends into the collar assembly 4. An annular groove 36 is formed at the upper end of the mounting bracket 3, and multiple locking ball assemblies 17 extend into the annular groove 36. The mounting bracket 3 and the mounting base 1 are fixedly connected, allowing the operator to align the collar assembly 4 with the mounting bracket 3 and make... With the end of the collar assembly 4 without the notch 34 facing downwards, it is easy for the collar assembly 4 to be pressed down so that the upper end of the mounting bracket 3 can be inserted into the collar assembly 4. The upper end of the mounting bracket 3 will squeeze the locking ball assembly 17, which can rotate against the outer wall of the mounting bracket 3 and transmit pressure to the telescopic rod assembly 39 and the spring 38. The two ends of the spring 38 are respectively fixed to the sleeve end and the telescopic end inside the telescopic rod assembly 39. The telescopic end of the telescopic rod assembly 39 can be inserted into the sleeve end of the telescopic rod assembly 39, and the spring 38 will retract. When the locking ball assembly 17 corresponds to the annular groove 36, the spring 38 returns to its original state, which will allow the locking ball assembly 17 to be inserted into the annular groove 36, thus completing the connection between the collar assembly 4 and the mounting bracket 3. Meanwhile, the locking ball assembly 17 can rotate relative to the telescopic rod assembly 39, and the telescopic rod assembly 39 can rotate around its center line, which facilitates the rotation of the collar assembly 4 relative to the mounting frame 3; the upper edge of the mounting frame 3 is arc-shaped, which facilitates the mounting frame 3 and the locking ball assembly 17 to abut against each other, and facilitates the locking ball assembly 17 to retract into the mounting groove 18.

[0034] In this embodiment, the conical sealing gasket assembly 14 is sealed and installed inside the collar assembly 4. A positioning connecting bolt 21 is provided through the collar assembly 4, and one end of the positioning connecting bolt 21 is threaded into the conical sealing gasket assembly 14. By rotating the positioning connecting bolt 21, the relative position between the conical sealing gasket assembly 14 and the collar assembly 4 can be fixed. In actual production and processing, workers can add corresponding sealing components around the conical sealing gasket assembly 14 to ensure that it is in full contact with the inner wall of the collar assembly 4. By deforming and filling the gaps, leakage and seepage can be avoided.

[0035] In this embodiment, the clamping mechanism includes a plurality of notches 34 that are equally spaced on the inner sidewall of the collar assembly 4. An abutting shaft 19 is installed on one sidewall of the notch 34. One side of the abutting shaft 19 abuts against an abutting point 23. One end of the abutting point 23 abuts against the measuring tube 5. A movable frame 22 is fixed on one side of the contact point 23. The lower end of the movable frame 22 is inserted through the notch 34. The side of the movable frame 22 away from the contact point 23 abuts against the contact shaft 19. A slide rail 25 is fixed at the top inside the movable frame 22. A lifting rod 26 is slidably installed on the slide rail 25. An annular cavity 40 is opened inside the mounting frame 3.

The operator can rotate the screw 20 to push the ring 24 down. The descent of the ring 24 can drive the lifting rod 26 down. The lifting rod 26 can drive the moving frame 22 down through the slide rail 25. When the moving frame 22 descends, its inclined inner sidewall will abut against the contact shaft 19, which can make the moving frame 22 move towards the axis of the collar assembly 4. The movement of the moving frame 22 can make the contact point 23 abut against the outer wall of the measuring tube 5. As the screw 20 continues to rotate, the moving frame 22 can drive the contact point 23 to move downward and inward. Multiple contact points 23 abut against the lower end of the measuring tube 5 at equal intervals, which can make the measuring tube 5 fully abut against the conical sealing gasket assembly 14 to complete the seal. After the test is completed, the staff can rotate the screw 20 so that the screw 20 drives the ring 24 to rise, so that the contact point 23 no longer applies a downward and inward force to the measuring tube 5. The movable frame 22 is tilted on the side away from the contact point 23; the movable frame 22 is in contact with the contact shaft 19 through the tilted side of the movable frame 22 so as to control the movable frame 22 to move downward and inward.

One end of the timing belt assembly 11 is connected to the output shaft of the motor assembly 12. The motor assembly 12 is connected to the corresponding power supply components and the control cabinet assembly 41, which can control the rotation speed of the motor assembly 12. When the collar assembly 4 and the mounting bracket 3 are connected, the two abutting transmission discs 33 can abut against each other. In order to ensure the transmission effect, friction textures or corresponding gears can be set on the opposite side of the two abutting transmission discs 33 to ensure the transmission effect. When the abutment transmission disc 33 rotates under the action of the motor assembly 12, it enables the vertical shaft 29 to drive the drive belt assembly 31 to operate. The operation of the drive belt assembly 31 enables the connecting pipe 27 to rotate. The connecting pipe 27 can drive the conical sealing gasket assembly 14, the aeration plate assembly 13 and the measuring pipe 5 to rotate. The drive belt assembly 31 consists of two wheels and a belt sleeved on the two wheels. Both the wheels and the belt are equipped with teeth. The meshing of the teeth can ensure the power transmission effect and facilitate the rotation of the measuring pipe 5.

The two pulleys are fixed to the transmission shaft assembly 9 and the linkage shaft 8 respectively, and the transmission shaft assembly 9 and the linkage shaft 8 can rotate synchronously through the action of the belt. The rotation of the output shaft of the motor assembly 12 enables the synchronous belt assembly 11 to drive the transmission shaft assembly 9 to rotate. The synchronous belt assembly 11 consists of two pulleys and a belt sleeved on the pulleys. The toothed structure enables the transmission shaft assembly 9 to rotate under the action of the motor assembly 12, which in turn enables the linkage shaft 8 to rotate. In actual operation, the detachable component 7 adopts a detachable locking structure, such as a press-type buckle, a plug-in buckle, etc., and corresponding components are installed on the upper end of the stirring component 6 to complete the locking. The stirring component 6 and the detachable component 7 can be quickly connected and their relative positions are fixed. The linkage shaft 8 drives the stirring component 6 to rotate, so that both the stirring component 6 and the measuring tube 5 can rotate. During operation, the agitator 6 can be set or not set depending on the actual situation, which can simulate the suspension state under flow conditions by whether the self-suspended proppant particles are agitated.

[0038] In this embodiment, a control cabinet assembly 41 is fixed on one side of the support frame 10.

The positioning rod 32 can be inserted into the positioning block 30 so that the vertical shaft 29 and the connecting pipe 27 will not rotate arbitrarily through the action of the notch 34, the positioning block 30, and the crossbar 28, ensuring their relative stability. For example, it can fully ensure that the two abutting transmission discs 33 can abut and transmit power. Furthermore, during actual production, the connection position between the vertical shaft 29 and the contact transmission disc 33 can be equipped with an elastic telescopic component, which can adapt to errors during processing and ensure that the two contact transmission discs 33 can fully contact each other.

[0040] In this invention, controlling the rotation direction of the screw 20 can limit the lifting and lowering of the ring 24, allowing the contact point 23 and the measuring tube 5 to contact or separate. Furthermore, lifting the collar assembly 4 can separate it from the mounting bracket 3, enabling efficient cleaning of the measuring tube 5, the conical sealing gasket assembly 14, and the collar assembly 4, facilitating high-quality subsequent testing. The aeration assembly 2 can inject clean, high-pressure gas into the rotating connecting pipe 16, the aeration pipe 15 with a one-way valve, and the aeration plate assembly 13. Simultaneously, the motor assembly 12 can control the rotation of the stirring component 6 and the measuring tube 5 to perform suspension performance testing of the self-suspending proppant.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
