Description

Technical Field

[0001] This utility model relates to the field of fracturing oil and gas reservoir technology, and in particular to an automatic proportioning and injection device for fracturing bactericides. Background Technology

[0002] my country's oil and gas reservoirs all contain a certain amount of clay minerals (such as kaolinite, montmorillonite, illite, chlorite, and illite-montmorillonite mixed layers). Fracturing refers to a method of creating fractures in oil and gas reservoirs using hydraulic force during oil or gas production; it is also known as hydraulic fracturing. Fracturing artificially creates fractures in the formation, improving the underground flow environment for oil and increasing well production. It plays an important role in improving bottomhole flow conditions, mitigating interlayer flow, and improving reservoir dynamics. Fracturing requires the use of fracturing fluid, and bactericides need to be added to the fracturing fluid, or bactericides can be sprayed at the fracturing site during the fracturing process to facilitate the operation.

[0003] In existing proportioning devices, the bottom of the proportioning cylinder is generally equipped with a connected discharge pipe. When the proportioning cylinder is mixing and proportioning various raw materials, the added raw materials will accumulate inside the connected discharge pipe, thereby increasing the residue in the later mixing process.

[0004] Therefore, it is necessary to provide a new automatic proportioning and dispensing device for fracturing bactericides to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic proportioning and dispensing device for fracturing bactericides.

[0007] The support frame is provided in two and fixedly installed on the two side walls of the mixing cylinder. A motor is fixedly installed on one side of the support frame. A lead screw is fixedly connected to the output end of the motor. A mating plate is threadedly connected to the lead screw. The other end of the lead screw is rotatably connected to the support frame. A guide rod is fixedly connected between the support frames. The guide rod is slidably connected to the mating plate.

[0008] The outer wall of the docking plate abuts against and slides against the inner wall of the docking groove, and both the inner wall of the docking groove and the outer wall of the docking plate are fixedly fitted with rubber sleeves.

[0009] Preferably, a mounting groove is provided on one side wall of the mixing cylinder and a mixing component is installed inside the mixing cylinder. The mixing component includes a side plate, and the outer wall of the side plate abuts against the inner wall of the mounting groove and is fixedly connected by bolts. A mixing motor is fixedly installed on the outer wall of the side plate, and a drive rod extending into the interior of the mixing cylinder is fixedly connected to the output end of the mixing motor.

[0010] Preferably, a support plate is vertically fixed on the drive rod, and multiple evenly distributed mixing frames are rotatably mounted on the support plate; a scraper is fixedly installed at the bottom end of the support plate, and the outer wall of the scraper abuts against and slides in connection with the inner wall of the proportioning cylinder and the outer wall of the docking plate.

[0011] Preferably, the top of the mixing cylinder is provided with a dispensing component for adding bactericide. The dispensing component includes a guide hopper, the interior of which is connected to and fixedly connected to the interior of the mixing cylinder, and a water pipe connected to the interior of the guide hopper is fixedly installed in the center of the interior of the guide hopper.

[0012] Preferably, the guide hopper is fixedly connected to multiple filling pipes, the top end of each filling pipe is fixedly installed with a connected storage cylinder, and a flow meter and a solenoid valve are fixedly installed on the filling pipe.

[0014] Compared with related technologies, the automatic proportioning and dispensing device for fracturing bactericides provided by this utility model has the following advantages:

[0015] 1. By setting up a docking component, this utility model allows the docking plate in the docking component to be moved from the side away from the docking hole to the part opposite to the docking groove in the mixing cylinder during the mixing process of various raw materials. At this time, the docking plate and the docking groove abut against each other, which can seal the inside of the mixing cylinder, so that a more regular plane can be formed inside the mixing cylinder. This reduces the probability of dead corners and residues of raw materials inside the mixing cylinder during mixing, thus improving the uniformity of raw material mixing in the later stage.

[0016] 2. Through the insertion and installation of the mixing component, the operator can disconnect the side plate from the mounting slot in the mixing cylinder as needed during subsequent use. Then, the drive rod and mixing frame can be disassembled and removed from the inside of the mixing cylinder through the side plate, which facilitates the operator to clean the inner wall of the mixing cylinder and inspect and replace the components in the mixing component.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 The present invention provides an automatic mixing and dispensing device for fracturing bactericide, which includes a frame 1.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4A mixing cylinder 2 for mixing disinfectant is fixedly installed on the frame 1. A docking groove 21 is opened at the bottom of the mixing cylinder 2. A docking assembly 3 is provided on the mixing cylinder 2, and a controller 11 is fixedly installed on the frame 1. The docking assembly 3 includes a support frame 31. Two support frames 31 are provided and fixedly installed on the two side walls of the mixing cylinder 2. A motor is fixedly installed on one side of the support frame 31. A lead screw 312 is fixedly connected to the output end of the motor. A docking plate 32 is threadedly connected to the lead screw 312. The other end of the lead screw 312 is rotatably connected to the support frame 31. A guide rod 311 is fixedly connected between the support frames 31. The guide rod 311 is slidably connected to the docking plate 32. The outer wall of the docking plate 32 abuts against and is slidably connected to the inner wall of the docking groove 21. Both the inner wall of the docking groove 21 and the outer wall of the docking plate 32 are fixedly installed with rubber sleeves.

[0026] A through-hole 321 is provided on one side of the inside of the docking plate 32. A pump body 33 is fixedly installed at the bottom of the docking plate 32 opposite to the docking hole 321. The input end of the pump body 33 is connected to the inside of the docking hole 321. A discharge pipe 331 is fixedly installed at the output end of the pump body 33, and a connected nozzle 332 is fixedly installed at the end of the discharge pipe 331 away from the pump body 33.

[0027] It should be noted that by movably installing the docking plate 32 and fitting a rubber sleeve on the outer wall of the docking plate 32 and the inner wall of the docking groove 21, when the docking plate 32 and the docking groove 21 come into contact, the rubber sleeve is deformed by compression, which makes the docking part of the docking plate 32 and the docking groove 21 more tightly sealed. This prevents the raw materials inside the mixing cylinder 2 from leaking from the connection between the docking groove 21 and the docking plate 32. Therefore, in subsequent use, when it is necessary to mix the raw materials, the side of the docking plate 32 away from the docking hole 321 can be moved to the position opposite to the docking groove 21 to seal the docking groove 21 in the mixing cylinder 2. This makes the inner wall of the mixing cylinder 2 form a regular planar structure, thereby reducing the phenomenon of dead corner residue of raw materials in the mixing cylinder 2 during mixing, thus helping to improve the mixing uniformity of the raw materials.

[0028] After the raw materials are mixed, the side of the docking plate 32 with the docking hole 321 can be moved to the opposite position of the docking groove 21. Then, when the pump body 33 is working, the mixed bactericide can flow into the pump body 33 through the docking hole 321, and the bactericide can be discharged outward through the nozzle 332 at the end of the discharge pipe 331.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4A mounting groove 22 is provided on one side wall of the mixing cylinder 2. A mixing component 5 for mixing and stirring the bactericide is installed inside the mixing cylinder 2. The mixing component 5 includes a side plate 51, and the outer wall of the side plate 51 abuts against the inner wall of the mounting groove 22 and is fixedly connected by bolts. A mixing motor 511 is fixedly installed on the outer wall of the side plate 51. A drive rod 52 extending into the interior of the mixing cylinder 2 is fixedly connected to the output end of the mixing motor 511.

[0030] A support plate 521 is vertically fixed on the drive rod 52. Multiple evenly distributed mixing frames 53 are rotatably mounted on the support plate 521. A scraper 522 is fixedly mounted at the bottom end of the support plate 521. The outer wall of the scraper 522 abuts against and slides with the inner wall of the proportioning cylinder 2 and the outer wall of the docking plate 32.

[0031] It should be noted that: by inserting and installing the mixing component 5, during subsequent use, the operator can disconnect the side plate 51 from the mounting slot 22 in the proportioning cylinder 2 as needed. Then, the drive rod 52 and the mixing frame 53 can be disassembled and removed from the inside of the proportioning cylinder 2 through the side plate 51, which facilitates the cleaning of the inner wall of the proportioning cylinder 2 and the inspection and replacement of the components in the mixing component 5.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 The top of the mixing cylinder 2 is provided with a filling component 4 for adding bactericide. The filling component 4 includes a guide hopper 41. The interior of the guide hopper 41 is connected to and fixedly connected to the interior of the mixing cylinder 2. A water filling pipe 43 connected to the interior of the guide hopper 41 is fixedly installed in the center of the guide hopper 41. Multiple filling pipes 411 are fixedly connected to the outside of the guide hopper 41. A storage cylinder 42 is fixedly installed at the top of the filling pipe 411. A flow meter 412 and a solenoid valve 413 are fixedly installed on the filling pipe 411.

[0033] It should be noted that when adding the bactericide raw materials, the flow meter 412 on the injection pipe 411 can monitor the added raw materials, thereby achieving automatic and accurate addition of the raw materials.

[0034] The working principle of the automatic proportioning and dispensing device for fracturing bactericides provided by this utility model is as follows:

[0035] When using this device, the operator can first control the lead screw 312 in the docking assembly 3 to rotate. The rotating lead screw 312 will drive the docking plate 32 to move on the outer wall of the guide rod 311 through the thread structure until the docking plate 32 moves to the side away from the docking hole 321 and to the part of the bottom of the mixing cylinder 2 that is opposite to the docking groove 21. This can achieve the sealing of the inside of the mixing cylinder 2 and make the inner wall of the mixing cylinder 2 form a more regular surface.

[0036] Then, as needed, the solenoid valves 413 on multiple filling pipes 411 can be opened, so that the raw materials inside the corresponding storage cylinder 42 flow into the mixing cylinder 2 through the guide bucket 41. At the same time, the external water pump can be controlled to work so that water is added into the mixing cylinder 2 through the water filling pipe 43. During this process, the controller 11 can monitor the added raw materials through the flow meter 412 to achieve accurate addition of raw materials.

[0037] After the various raw materials are added, the mixing motor 511 in the mixing assembly 5 can be controlled to work. The working mixing motor 511 will drive the drive rod 52 and its external scraper 522 and mixing frame 53 to rotate. At this time, the rotating scraper 522 will scrape the bottom of the inner wall of the mixing cylinder 2, thereby turning the raw materials inside the mixing cylinder 2 over. The rotating mixing frame 53 can smoothly mix and stir the various raw materials. During this process, due to the relatively regular planar structure of the inner wall of the mixing cylinder 2, the residue of dead corners on the inner wall of the mixing cylinder 2 during mixing can be reduced, thus helping to improve the uniformity of the raw materials during mixing.

[0038] After the various raw materials are mixed, when the bactericide to be mixed and shaped needs to be added, the screw 312 can be controlled to rotate. The rotating screw 312 will drive the docking plate 32 to move until the docking hole 321 in the docking plate 32 moves to the part in the proportioning cylinder 2 opposite to the docking groove 21. Then the docking hole 321 can be connected to the inside of the proportioning cylinder 2. After the docking plate 32 is moved, the pump body 33 can be controlled to work. The working pump body 33 will be introduced into the nozzle 332 at the end of the discharge pipe 331 through the docking hole 321 and discharged outward through the nozzle 332, thereby realizing the addition of bactericide.

[0039] When the device is no longer in use, the staff can loosen the bolts connecting the side plate 51 to the mixing cylinder 2 as needed. Then, by holding the handle on the side plate 51, the staff can move the drive rod 52 and its components out of the mixing cylinder 2. This makes it easier for the staff to clean the inner wall of the mixing cylinder 2 and to repair and replace components such as the mixing frame 53.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
