Description

Technical Field

[0001] The present invention relates to the technical field of drag reducer mixing preparation, and particularly to a device and method for proportioning and synthesizing a clean drag reducer for oil and gas wells. Background Technique

[0002] With the extension of oil and gas field development to deep wells, ultra-deep wells and complex formations, the downhole high-temperature and high-pressure, multiphase fluid environment has put forward higher requirements for the performance of drilling fluids. As the core treatment agent for reducing the friction of the pipe string and inhibiting the deposition of cuttings, the mixing uniformity of the clean drag reducer for oil and gas wells directly affects the smooth effect of the operation.

[0003] At present, the traditional synthesis device uses a combination of a single reaction kettle and mechanical stirring to stir and mix the synthesized substances. Before mixing, the substances of each component need to be proportioned in advance and then poured into the reaction kettle at one time for stirring and mixing. Especially for high-viscosity materials such as clean drag reducers, one-time input is likely to cause a sudden increase in stirring resistance, and the substances are prone to caking and sedimentation. At the same time, for components with intense exothermic or fast reaction rates (such as acid substances and alkaline regulators), local overheating is likely to cause decomposition or side reactions, resulting in the risk of reaction out of control. It is impossible to achieve batch synchronous feeding during normal operation, and the equipment needs to be started and stopped multiple times, which is likely to cause the risk of operation errors, as well as the problems of cumbersome operation and low efficiency. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device and method for proportioning and synthesizing a clean drag reducer for oil and gas wells, which have the advantages of being able to feed multiple substances synchronously and batchwise during operation, improving the mixing uniformity of substances, reducing the stirring resistance and the risk of reaction out of control, etc., and solving the problems of sudden increase in stirring resistance, easy caking and sedimentation of substances, as well as intense exothermic, high reaction rate, and easy decomposition and side reactions caused by local overheating in the current stage of one-time feeding.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: A device for proportioning and synthesizing a clean drag reducer for oil and gas wells, comprising a reaction kettle, an inner cylinder, a cover plate, a cleaning member and a stirring member. A regulation groove is opened in the reaction kettle, and a main spring and a secondary spring are fixed in the regulation groove. The elastic forces of the main spring and the secondary spring are the same. There is one main spring, which is fixed at the central position in the regulation groove, and there are four secondary springs, which are equidistantly fixed in the regulation groove and are located between the center and the edge.

[0008] An inner cylinder is movably sleeved in the regulation groove. One ends of the main spring and the auxiliary spring are fixed to the bottom of the inner cylinder. The diameter of the side part of the inner cylinder matches the diameter in the regulation groove, so as to ensure the stability of the up-and-down displacement of the inner cylinder in the regulation groove. When the inner cylinder is displaced downward under pressure, the main spring and the auxiliary spring are compressed. When there is no pressure on the top of the inner cylinder, the inner cylinder is pushed upward to return to the initial position by the expansion of the main spring and the auxiliary spring.

[0009] A plurality of interfaces penetrating through the regulation groove are provided on the reactor. Fasteners are installed on the interfaces. At the same time, a flexible hose is movably sleeved on the side part of the inner cylinder, and the fasteners are movably connected to the side of the flexible hose. The plurality of interfaces are arranged at equal intervals in the vertical direction. A flexible hose is sleeved in each interface, and the flexible hose is fixed in the interface through the fasteners in the interface. Different components of materials are conveyed into the inner cylinder through the flexible hose and an external feeding device.

[0010] The flexible hose has a high elastic force and can be stretched intensively, ensuring the flexibility of the flexible hose and facilitating connection and storage.

[0011] A cover plate is movably connected to the reactor. A driving groove is provided in the cover plate. A sealing cover is installed on the driving groove. A driving member one is installed in the driving groove, and a driving member two is installed on the sealing cover. The cover plate has the same size as the top of the reactor, so as to seal the regulation groove by closing the cover plate and the top of the reactor. At the same time, the driving member one is used to provide a rotational force, and the driving member two is used to provide a lifting force for height change.

[0012] A cleaning member and a stirring member are movably connected to the bottom of the cover plate and are movably sleeved in the inner cylinder. The cleaning member is used for scraping the material on the inner wall of the inner cylinder, and the stirring member is used for fully stirring the material in the inner cylinder.

[0013] The cleaning member and the stirring member are connected to the driving member one and the driving member two, and are used to control the rotation and height displacement change of the cleaning member and the stirring member. The driving member one controls the cleaning member to scrape the residual material on the inner wall of the inner cylinder into the inner cylinder and drives the stirring member to fully stir the material, so that the material is fully mixed. The driving member two controls the lifting of the cleaning member and the stirring member and simultaneously pushes the inner cylinder to displace in height. When the inner cylinder displaces, the feeding rate and size are controlled by the misaligned extrusion of the flexible hose.

[0014] As a further improvement of the above solution, a pneumatic telescopic rod is provided at the bottom of the cover plate. At the same time, an interface is provided on the reactor, and one end of the pneumatic telescopic rod is fixed in the interface.

[0015] A limiting ring is also fixed to the bottom of the cover plate, and the limiting ring fits on the top of the inner cylinder.

[0016] Through the above technical solution, pneumatic telescopic rods are installed at the four corner positions at the bottom of the cover plate. At the same time, interfaces are provided at the four corner positions at the top of the reactor. The output ends of the pneumatic telescopic rods are fixed in the interfaces. At the same time, the four pneumatic telescopic rods operate synchronously, so as to realize the stable opening and closing of the cover plate and the reactor.

[0017] As a further improvement of the above solution, the fastener includes a retaining ring fixed on the interface. A stabilizing ring is movably sleeved in the retaining ring, and the stabilizing ring is fixed on the side of the hose.

[0018] A fixing screw is threadedly connected to the side of the retaining ring. One end of the fixing screw penetrates into the stabilizing ring and abuts against the side of the hose.

[0019] Through the above technical solution, the overall diameter of the stabilizing ring is consistent with the diameter inside the retaining ring, improving the stability of the stabilizing ring sleeved in the retaining ring. After the stabilizing ring is sleeved at an appropriate position on the side of the hose, it is fixed by glue bonding. When the stabilizing ring is sleeved in the retaining ring, by rotating the fixing screw, the front end of the fixing screw is pressed against the side of the stabilizing ring, so as to fix the stabilizing ring and the hose, avoiding the phenomenon of hose detachment caused by misalignment extrusion during the height displacement of the inner cylinder.

[0020] As a further improvement of the above solution, a pressing plate is movably sleeved in the stabilizing ring. A stabilizing rod is fixed on the pressing plate. The stabilizing rod penetrates through the side of the stabilizing ring, and at the same time, the pressing plate abuts against the side of the hose.

[0021] Through the above technical solution, the fixing screw is inserted into the round hole of the stabilizing ring it penetrates. In the state of continuous rotation, the front end of the fixing screw gradually moves into the stabilizing ring, thereby pushing the pressing plate to squeeze the hose, so as to set the flow rate of material transportation.

[0022] As a further improvement of the above solution, on the basis of Embodiment 1 and Embodiment 2, this embodiment further includes that the driving member 1 includes a gear 1 and a gear 2 rotatably connected in the driving groove. The gear 1 and the gear 2 are meshed with each other, and a conduction gear is fixed on the gear 2.

[0023] The driving member 1 further includes a motor fixed in the driving groove. A driving gear is fixed on the output end of the motor. A transmission belt is meshed with the side parts of the driving gear and the conduction gear.

[0024] Through the above technical solution, when the motor operates, the output end drives the driving gear to rotate. Under the transmission of the transmission belt, the conduction gear rotates synchronously. The conduction gear drives the gear 2 at the bottom to rotate. Through the meshing action with the gear 1, the gear 1 rotates in the reverse direction.

[0025] As a further improvement of the above solution, a special-shaped rod one is fixed at the bottom of the first gear. A special-shaped rod two is movably sleeved inside the second gear and the transmission gear. A linkage button is provided on the special-shaped rod one and the special-shaped rod two, and a linkage plate is rotatably connected to the side of the linkage button.

[0026] Through the above technical solution, a linkage button is movably sleeved on the side of the special-shaped rod one, and a linkage button is fixed at one end of the special-shaped rod two. When the height of the special-shaped rod two changes, the linkage button is driven by the linkage plate to move up and down, so that the special-shaped rod two and the special-shaped rod one achieve synchronous height displacement, and when the displacement changes, it does not affect the rotation effect of the special-shaped rod one and the special-shaped rod two.

[0027] As a further improvement of the above solution, a rotating rod is movably sleeved at one end of the special-shaped rod one.

[0028] The cleaning part includes a connecting rod fixed at one end of the rotating rod. Shrinkable rods are movably sleeved on both sides of the connecting rod. An installation rod is fixed at one end of the shrinkable rod, and a scraper is fixed at one end of the installation rod. The scraper fits on the inner wall of the inner cylinder.

[0029] Through the above technical solution, a hole matching the shape and size of the side of the special-shaped rod one is opened inside the top of the rotating rod. When the special-shaped rod one rotates, it drives the rotating rod and the connecting rod at the bottom to rotate, so that the scraper scrapes the materials left on the inner wall of the inner cylinder to the middle of the inner cylinder.

[0030] As a further improvement of the above solution, a tension spring is movably sleeved on the side of the shrinkable rod, and both ends of the tension spring are attached to the connecting rod and the installation rod.

[0031] Through the above technical solution, under the driving force of the tension spring unfolding, the installation rod drives the scraper to stably fit on the inner wall of the inner cylinder, so that when the cleaning part rotates, the scraper can fully scrape the materials on the inner wall of the inner cylinder.

[0032] As a further improvement of the above solution, a transmission gear is fixed at one end of the special-shaped rod two.

[0033] The stirring part is composed of a sleeve and a toothed disc. The toothed disc is fixed at one end of the sleeve. The sleeve is rotatably connected to the side of the rotating rod, and at the same time the toothed disc meshes with the transmission gear.

[0034] Through the above technical solution, when the special-shaped rod two drives the transmission gear to rotate, under the meshing action of the transmission gear and the toothed disc, the toothed disc drives the sleeve to rotate in the opposite direction, realizing the reverse operation of the cleaning part and the stirring part, scraping the materials while mixing the materials, and improving the mixing degree of the material stirring.

[0035] As a further improvement of the above solution, a plurality of stirring rods are fixed on the side of the sleeve, and one end of the stirring rod is located inside the scraper.

[0036] Through the above technical solution, multiple stirring rods are arranged at equal intervals. When rotating, they can stir materials at different heights. During the rotating stirring process, since the length of the stirring rod is shorter than the horizontal length of the scraper, the collision between the stirring rod and the scraper can be avoided, ensuring the stability of the operation of the stirring rod and the scraper.

[0037] As a further improvement of the above solution, the second driving member includes an electric telescopic rod fixed on the sealing cover. A connecting plate is fixed on the output end of the electric telescopic rod, and one end of the connecting plate is rotatably connected to the second special-shaped rod.

[0038] Through the above technical solution, when the electric telescopic rod operates, the output end drives the second special-shaped rod through the connecting plate to achieve height change, and at the same time, it does not affect the rotation of the second special-shaped rod.

[0039] An implementation method of an oil and gas well cleaning drag reducer proportioning and synthesizing device includes the following steps:

[0040] S1: Pass the front ends of multiple hoses through the corresponding interfaces and fasteners, and connect them to the feeding devices of different materials. At the same time, the fasteners fix the tail ends of the hoses to complete the connection and operation of the feeding relationship between the feeding device and this device.

[0041] S2: By rotating the fixing screws on different fasteners, adjust the extrusion deformation degree of the pressing plate on the hose to adjust the difference in the feeding volume ratio of different hoses during synchronous feeding.

[0042] S3: Control the first driving member to operate, so that the cleaning member and the stirring member rotate in opposite directions, so that the cleaning member scrapes off the materials on the inner wall of the inner cylinder and concentrates them towards the middle, and at the same time, the stirring member fully stirs the materials.

[0043] S4: Control the second driving member to operate, so that the output end of the electric telescopic rod retracts downward into the interior, so that the rotating rod pushes the inner cylinder downward to misalign and squeeze the hoses to control the flow rate and flow volume of the material transportation.

[0044] S5: Control the output end of the electric telescopic rod to retract completely, so that the inner cylinder moves down to the lowest end, and the hoses are completely squeezed into a flat shape and closed. At this time, under the continuous operation of the first driving member, the cleaning member and the stirring member fully stir and scrape the materials until the materials are fully mixed.

[0045] Compared with the prior art, the present invention provides an oil and gas well cleaning drag reducer proportioning and synthesizing device and method, which have the following beneficial effects:

[0046] 1. The device and method for proportioning and synthesizing a cleaning and drag-reducing agent for oil and gas wells install multiple hoses on the side of the inner cylinder. Under the control of the second driving member to lift the rotating rod and the reverse pushing force of the main spring and the auxiliary spring, the misaligned extrusion of the hoses on the interface is realized. Thus, under the normal operation of the stirring member, the synchronous batch feeding of multiple substances and the synchronous control of the feeding flow rate are achieved, and then the materials are gradually and fully mixed, effectively avoiding the sudden increase in stirring resistance caused by the one-time input of high-viscosity materials. At the same time, the efficiency of heat dispersion and release of substances is improved, preventing decomposition and side effects caused by local overheating, and reducing the risk of reaction runaway.

[0047] 2. The device and method for proportioning and synthesizing a cleaning and drag-reducing agent for oil and gas wells control the synchronous operation of the cleaning member and the stirring member through the first driving member. While the stirring member stirs the mixed substances, the cleaning member rotates in the opposite direction. The substances adhered to the inner wall and bottom of the inner cylinder are scraped off by the scraper and concentrated towards the center along the rotating direction, avoiding the formation of an adhesion layer. At the same time, under the action of the opposite rotation of the cleaning member and the stirring member, extrusion stirring is realized, thereby further improving the mixing quality of the substances.

[0048] 3. The device and method for proportioning and synthesizing a cleaning and drag-reducing agent for oil and gas wells, through the design of fasteners on the interface, can preset the proportions of different substances transported in the preparation of the same batch of drag-reducing agents, thus effectively reducing the operational complexity of preparing the same batch of drag-reducing agents multiple times. At the same time, it can be manually adjusted during the normal operation of the device, further improving the practicability and flexibility of the device. Description of the Drawings

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Embodiment 1

[0068] Please refer to Figures 1-4As shown in the figure, a device for proportioning and synthesizing a cleaning and drag - reducing agent for oil and gas wells proposed in this embodiment includes a reaction kettle 1, an inner cylinder 2, a cover plate 3, a cleaning part 4, and a stirring part 5. A regulation groove 11 is provided in the reaction kettle 1. A main spring 111 and auxiliary springs 112 are fixed in the regulation groove 11. The elastic forces of the main spring 111 and the auxiliary springs 112 are the same. There is one main spring 111, which is fixed at the central position in the regulation groove 11. There are four auxiliary springs 112, which are equidistantly fixed in the regulation groove 11 and are located between the center and the edge.

[0069] An inner cylinder 2 is movably sleeved in the regulation groove 11. One end of the main spring 111 and the auxiliary springs 112 is fixed to the bottom of the inner cylinder 2. The diameter of the side part of the inner cylinder 2 matches the diameter in the regulation groove 11, so as to ensure the stability of the up - and - down displacement of the inner cylinder 2 in the regulation groove 11. When the inner cylinder 2 is displaced downward under pressure, the main spring 111 and the auxiliary springs 112 are compressed. When there is no pressure on the top of the inner cylinder 2, the main spring 111 and the auxiliary springs 112 expand to push the inner cylinder 2 back to the initial position upward.

[0070] It should be further noted that the main spring 111 plays a major role in supporting and resetting, while the auxiliary springs 112 are used to ensure the stability of the inner cylinder 2 during height displacement changes and prevent tilting.

[0071] A plurality of interfaces 12 penetrating the regulation groove 11 are provided on the reaction kettle 1. Fasteners 13 are installed on the interfaces 12. At the same time, a flexible hose 21 is provided on the side of the inner cylinder 2 and is movably sleeved in the interface 12, and the fastener 13 is movably connected to the side of the flexible hose 21.

Different components of materials are transported into the inner cylinder 2 through the flexible hose 21 and an external feeding device.

[0072] The flexible hose 21 has a high elastic force and can be stretched strongly, ensuring the flexibility of the flexible hose 21 and facilitating connection and storage.

[0073] It should be further noted that the materials transported by each feeding device are all components for preparing the cleaning and drag - reducing agent for oil and gas wells, such as: polymer, surfactant, acid substance, chelating agent, dispersant, corrosion inhibitor, pH regulator, solvent, bactericide, defoamer, etc. Specifically, it is determined according to the actual material composition for manufacturing the drag - reducing agent, and no specific limitation is made here, so as to realize the transportation of different components of materials into the inner cylinder 2.

[0074] A cover plate 3 is movably connected to the reactor 1. A driving groove 31 is provided inside the cover plate 3. A sealing cover 32 is installed on the driving groove 31. A first driving member 33 is installed in the driving groove 31. A second driving member 34 is installed on the sealing cover 32. The cover plate 3 has the same size as the top of the reactor 1. Thus, by closing the top of the reactor 1 with the cover plate 3, the regulation groove 11 can be sealed. At the same time, the first driving member 33 is used to provide a rotational force, and the second driving member 34 is used to provide a lifting force for height change.

[0075] A cleaning member 4 and a stirring member 5 are movably connected to the bottom of the cover plate 3 and are movably sleeved in the inner cylinder 2. The cleaning member 4 is used for scraping the inner wall of the inner cylinder 2, and the stirring member 5 is used for fully stirring the materials in the inner cylinder 2.

[0076] The cleaning member 4 and the stirring member 5 are connected to the first driving member 33 and the second driving member 34 to control the rotation and height displacement changes of the cleaning member 4 and the stirring member 5. The first driving member 33 controls the cleaning member 4 to scrape the remaining materials on the inner wall of the inner cylinder 2 into the inner cylinder 2 and drives the stirring member 5 to fully stir the materials to make the materials fully mixed. The second driving member 34 controls the lifting of the cleaning member 4 and the stirring member 5, and at the same time pushes the inner cylinder 2 to displace in height. When the inner cylinder 2 displaces, by misaligned extrusion of the hose 21, the flow rate and size of the feeding amount are controlled.

[0077] Further, a pneumatic telescopic rod 35 is provided at the bottom of the cover plate 3. At the same time, an interface 12 is opened on the reactor 1, and one end of the pneumatic telescopic rod 35 is fixed in the interface 12.

[0078] A limiting ring 36 is also fixed at the bottom of the cover plate 3, and the limiting ring 36 fits on the top of the inner cylinder 2.

At the same time, interfaces are opened at the four corner positions at the top of the reactor 1. The output ends of the pneumatic telescopic rods 35 are fixed in the interfaces. At the same time, the four pneumatic telescopic rods 35 operate synchronously, so as to realize the stable opening and closing of the cover plate 3 and the reactor 1.

[0080] Embodiment 2

[0081] Please refer to Figures 4-5 and Figure 11 As shown, the oil and gas well cleaning and drag reduction agent proportioning and synthesizing device proposed in this embodiment, on the basis of Embodiment 1, this embodiment further includes that the fastener 13 includes a retaining ring 131 fixed on the interface 12. A stabilizing ring 132 is movably sleeved in the retaining ring 131, and the stabilizing ring 132 is fixed on the side of the hose 21.

[0082] A fixing screw 133 is threadedly connected to the side of the retaining ring 131. One end of the fixing screw 133 passes through the stabilizing ring 132 and fits on the side of the hose 21.

[0083] More specifically, the diameter of the whole stabilizing ring 132 matches the diameter inside the retaining ring 131, improving the stability of the stabilizing ring 132 sleeved inside the retaining ring 131. After the stabilizing ring 132 is sleeved at an appropriate position on the side of the hose 21, it is fixed by glue bonding. Thus, when the stabilizing ring 132 is sleeved inside the retaining ring 131, by rotating the fixing screw 133, the front end of the fixing screw 133 is closely attached to the side of the stabilizing ring 132, realizing the fixation of the stabilizing ring 132 and the hose 21, and avoiding the phenomenon that the hose 21 falls off due to the misalignment extrusion caused by the height displacement of the inner cylinder 2.

[0084] Furthermore, a pressing plate 134 is movably sleeved inside the stabilizing ring 132. A stabilizing rod 135 is fixed on the pressing plate 134. The stabilizing rod 135 penetrates through the side of the stabilizing ring 132, and at the same time, the pressing plate 134 is attached to the side of the hose 21.

[0085] More specifically, the fixing screw 133 is inserted into the circular hole of the stabilizing ring 132 it penetrates through. In the state of continuous rotation, the front end of the fixing screw 133 gradually moves towards the inside of the stabilizing ring 132, thereby pushing the pressing plate 134 to extrude the hose 21, realizing the setting of the flow rate of material transportation.

[0086] It should be further noted that by rotating the fixing screws 133 on different interfaces 12, the pressing plate 134 extrudes the hose 21 to different deformation sizes, realizing the setting of the proportion of material components.

[0089] The driving member 33 further includes a motor 334 fixed in the driving groove 31. A driving gear 335 is fixed on the output end of the motor 334. A transmission belt 336 is meshed with the side parts of the driving gear 335 and the conducting gear 333.

[0090] More specifically, when the motor 334 operates, the output end drives the driving gear 335 to rotate. Under the transmission of the transmission belt 336, the conducting gear 333 rotates synchronously. The conducting gear 333 drives the gear 332 at the bottom to rotate, and under the meshing action with the gear 331, the gear 331 rotates in the opposite direction.

[0091] Further, a special-shaped rod one 337 is fixed to the bottom of the gear one 331. A special-shaped rod two 338 is movably sleeved inside the gear two 332 and the transmission gear 333. A linkage button 339 is provided on the special-shaped rod one 337 and the special-shaped rod two 338. A linkage plate 340 is rotatably connected to the side of the linkage button 339.

[0092] More specifically, the linkage button 339 is movably sleeved on the side of the special-shaped rod one 337, and the linkage button 339 is fixed to one end of the special-shaped rod two 338. When the height of the special-shaped rod two 338 changes, the linkage button 339 is driven by the linkage plate 340 to move up and down, so that the special-shaped rod two 338 and the special-shaped rod one 337 achieve synchronous height displacement, and when the displacement changes, it does not affect the rotation effect of the special-shaped rod one 337 and the special-shaped rod two 338.

[0093] Further, a rotating rod 3371 is movably sleeved on one end of the special-shaped rod one 337.

[0094] The cleaning part 4 includes a connecting rod 41 fixed to one end of the rotating rod 3371. Shrinkage rods 411 are movably sleeved on both sides of the connecting rod 41. An installation rod 412 is fixed to one end of the shrinkage rod 411. A scraper 42 is fixed to one end of the installation rod 412. The scraper 42 is attached to the inner wall of the inner cylinder 2.

[0095] More specifically, a hole is formed inside the top of the rotating rod 3371, which is in line with the shape and size of the side of the special-shaped rod one 337. When the special-shaped rod one 337 rotates, the rotating rod 3371 and the connecting rod 41 at the bottom are driven to rotate, so that the scraper 42 scrapes the materials remaining on the inner wall of the inner cylinder 2 to the middle of the inner cylinder 2.

[0096] It should be further noted that the shrinkage rod 411 is perpendicular to the connecting rod 41, so that the two shrinkage rods 411 on both sides are arranged horizontally opposite to each other. The installation rod 412 is in a right-angled shape, and one end faces downwards and is used to fix the scraper 42. At the same time, the scraper 42 is in a right-angled shape, one end is attached to the bottom of the inner cylinder 2, and the other end is attached to the inner wall of the inner cylinder 2, so that it can effectively scrape the materials remaining in the inner cylinder 2 and concentrate them towards the central position.

[0097] Further, a tension spring 413 is movably sleeved on the side of the shrinkage rod 411. The two ends of the tension spring 413 are attached to the connecting rod 41 and the installation rod 412.

[0098] More specifically, under the driving force of the tension spring 413 unfolding, the installation rod 412 drives the scraper 42 to be stably attached to the inner wall of the inner cylinder 2, so that when the cleaning part 4 rotates, the scraper 42 can fully scrape the materials on the inner wall of the inner cylinder 2.

[0099] Further, a transmission gear 3381 is fixed to one end of the special-shaped rod two 338.

[0100] The stirring member 5 is composed of a sleeve 51 and a toothed disc 52. The toothed disc 52 is fixed to one end of the sleeve 51. The sleeve 51 is rotatably connected to the side of the rotating rod 3371. At the same time, the toothed disc 52 meshes with the transmission gear 3381.

[0101] More specifically, when the special-shaped rod two 338 drives the transmission gear 3381 to rotate, under the meshing force of the transmission gear 3381 and the toothed disc 52, the toothed disc 52 drives the sleeve 51 to rotate in the reverse direction, realizing the reverse operation of the cleaning member 4 and the stirring member 5, scraping the material while mixing the material, and improving the mixing degree of the material stirring.

[0102] Further, a plurality of stirring rods 511 are fixed to the side of the sleeve 51. One end of each stirring rod 511 is located inside the scraper 42.

[0103] More specifically, the plurality of stirring rods 511 are arranged at equal intervals. When rotating, they can stir the materials at different heights. During the rotating stirring process, since the length of the stirring rod 511 is shorter than the horizontal length of the scraper 42, the stirring rod 511 can be prevented from colliding with the scraper 42, ensuring the stability of the operation of the stirring rod 511 and the scraper 42.

[0104] Further, the driving member two 34 includes an electric telescopic rod 341 fixed to the sealing cover 32. A connecting plate 342 is fixed to the output end of the electric telescopic rod 341. One end of the connecting plate 342 is rotatably connected to the special-shaped rod two 338.

[0105] More specifically, when the electric telescopic rod 341 operates, the output end drives the special-shaped rod two 338 to change its height through the connecting plate 342, without affecting the rotation of the special-shaped rod two 338.

[0106] The working principle of the device and method for proportioning and synthesizing the cleaning and drag-reducing agent for oil and gas wells proposed in this embodiment is as follows: First, in the shutdown state, by rotating the fixed screw 133, the pressing plate 134 squeezes the hose 21 to adjust the proportion of the conveying amounts of different materials, and the other ends of multiple hoses 21 are respectively connected to different feeding devices and operated. At this time, control the operation of the first driving member 33 and the second driving member 34, so that the cleaning member 4 and the stirring member 5 rotate synchronously in the opposite direction. The materials on the inner wall of the inner cylinder 2 are scraped off by the scraper 42 and concentrated towards the middle of the inner cylinder 2 along the rotation direction. At this time, the stirring member 5 stirs the materials to fully mix the materials while stirring. At the same time, by controlling the telescopic operation of the output end of the electric telescopic rod 341, the rotating rod 3371 pushes the inner cylinder 2 downward, so that the hose 21 is misaligned with the interface 12 to control the flow rate and flow amount of the materials conveyed in the hose 21 in real time. After the materials in the inner cylinder 2 reach the upper limit of the required preparation amount, the output end of the electric telescopic rod 341 is completely retracted into the interior, so that the rotating rod 3371 pushes the inner cylinder 2 downward to the limit. At this time, the hose 21 is completely flattened and closed under the misaligned extrusion, and then stop the operation of the external feeding device. At this time, relying solely on the acting force of the first driving member 33, the cleaning member 4 and the stirring member 5 fully mix the materials, and then control all components to stop operating, and control the output end of the pneumatic telescopic rod 35 to extend, so that the cover plate 3 is separated from the top of the reaction kettle 1. At this time, the cleaning member 4 and the stirring member 5 are separated from the inner cylinder 2, and then the mixed and prepared materials can be taken out.

[0107] Example 4

[0108] Please refer to Figures 1-10 The implementation method of any of the devices for proportioning and synthesizing the cleaning and drag-reducing agent for oil and gas wells is as follows:

[0109] S1: Pass the front ends of multiple hoses 21 through the corresponding interfaces 12 and fasteners 13, and connect them to the feeding devices of different materials. At the same time, the fasteners 13 fix the tail ends of the hoses 21 to complete the connection and operation of the feeding relationship between the feeding device and this device.

[0110] S2: By rotating the fixed screws 133 on different fasteners 13, adjust the extrusion deformation degree of the pressing plate 134 on the hose 21 to adjust the difference in the feeding amount ratio of different hoses during synchronous feeding.

[0111] S3: Control the operation of the first driving member 33 to make the cleaning member 4 and the stirring member 5 rotate in the opposite direction, so that the cleaning member 4 scrapes and processes the materials on the inner wall of the inner cylinder 2 and concentrates them towards the middle, and at the same time the stirring member 5 fully stirs the materials.

[0112] S4: Control the operation of the second driving member 34 to make the output end of the electric telescopic rod 341 retract downward into the interior, so that the rotating rod 3371 pushes the inner cylinder 2 downward to misalign and squeeze the hose 21 to control the flow rate and flow amount of the material conveyance.

[0113] S5: Control the output end of the electric telescopic rod 341 to retract completely, lower the inner cylinder 2 to the bottommost position, and completely squeeze the hose 21 into a flat shape and close it. At this time, under the continuous operation of the first driving member 33, the cleaning member 4 and the stirring member 5 fully stir and scrape the material until the material is fully mixed.
