However, existing water injection well profile adjustment and water drive injection devices are single-pump systems with limited pump capacity, unable to meet the needs of large-volume injection.

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] See Figures 1 to 3The figure shows a preferred structure of the online profile control and drive skid-mounted device in this embodiment. As shown, the online profile control and drive skid-mounted device includes: a support device 1, a drug delivery mechanism 2, a mixing tank 3, at least one partition 4, at least two mixing devices 6, at least two drug discharge mechanisms 7, and a confluence pipe 8. The support device 1 is a frame structure, specifically, it is cuboid in shape and includes: a base plate, a top plate 101, multiple parallel uprights 102, and multiple parallel crossbars 103; wherein the base plate and the top plate 101 are parallel, each upright 102 is vertically positioned between the base plate and the top plate 101, and each crossbar 103 is horizontally positioned between two adjacent uprights 102.
[0021] In practice, the support device 1 is a frame welded from 180×70×9 mm hot-rolled channel steel and 90×70×4 mm square tube, and the maximum stress of the support device 1 is 89.2 MPa.
[0022] The top of the support device 1 is provided with multiple lifting rings 14, specifically, the lifting rings 14 are spaced apart on the top plate 101. The lifting rings 14 facilitate the lifting of the support device 1, thus realizing the lifting of the online profile adjustment and drive skid mounting device. In specific implementation, there are four lifting rings 14, each located at one of the four corners of the top plate 101. Each lifting ring 14 is welded to the top of the support device 1. In specific implementation, each lifting ring 14 uses a 10 mm radius arc transition to eliminate the risk of stress concentration.
[0023] The drug delivery mechanism 2, the mixing tank 3, the various drug discharge mechanisms 7, and the confluence pipe 8 are all housed within the support device 1. The partitions 4 are arranged side-by-side, and are spaced apart within the mixing tank 3, thus dividing the interior of the mixing tank 3 into at least two mixing chambers 5. Specifically, the mixing tank 3 is rectangular in shape, with the partitions 4 parallel to each other and perpendicular to the length of the mixing tank 3, thus each partition 4 is horizontally positioned within the mixing tank 3, dividing the mixing tank 3 along its length. Each mixing chamber 5 has a preset volume, which can be determined based on actual conditions; this embodiment does not impose any limitations on this.
[0024] The drug delivery mechanism 2 is positioned above the mixing tank 3 (relative to...). Figure 1 In addition, the drug delivery mechanism 2 is connected to the inlet of each stirring chamber 5, and the drug delivery mechanism 2 is used to deliver the drug into each stirring chamber 5.
[0025] The number of stirring devices 6 is the same as the number of stirring chambers 5. Each stirring device 6 corresponds one-to-one with each stirring chamber 5. Each stirring device 6 is set in the corresponding stirring chamber 5. Each stirring device 6 is used to stir the medicine in the stirring chamber 5.
[0026] The number of dispensing mechanisms 7 is the same as the number of mixing chambers 5, with each dispensing mechanism 7 corresponding to one of the mixing chambers 5. Each dispensing mechanism 7 is connected to the outlet of its corresponding mixing chamber 5, and each dispensing mechanism 7 is connected to a manifold 8. Each dispensing mechanism 7 is used to transport the mixed agent to the manifold 8. The manifold 8 is used to connect to the injection well, and it is used to mix the agents transported by each dispensing mechanism 7 and then transport the mixed agent to the injection well.
[0027] Each dispensing mechanism 7 and the manifold 8 are located below the mixing tank 3. Specifically, each dispensing mechanism 7 is located below each mixing chamber 5, and the manifold 8 is located below each dispensing mechanism 7.
[0028] In practice, each partition 4 can be a 3 mm thick 316L stainless steel partition. The volume of each mixing chamber 5 is 1 cubic meter.
[0029] As can be seen, in this embodiment, the partitions 4 are arranged side by side inside the mixing tank 3, thereby dividing the interior of the mixing tank 3 into at least two mixing chambers 5. The drug delivery mechanism 2 delivers the drug to each mixing chamber 5 inside the mixing tank 3. The stirring device 6 in each mixing chamber 5 stirs the drug, making the drug evenly mixed and avoiding drug stratification. The evenly mixed drug in each mixing chamber 5 is delivered to the manifold 8 through the corresponding drug discharge mechanism 7. The manifold 8 delivers the drug to the injection well. In this way, the mixing tank 3 is no longer a single chamber as in the prior art, and can hold more drugs. The drugs are then delivered to the injection well through each drug discharge mechanism 7 and the manifold 8, which greatly increases the drug delivery volume and can meet the needs of large-dose injection. This solves the problem of small single pump displacement and uneven drug mixing in the prior art of water injection well profile adjustment and drive injection devices. In addition, the drug delivery mechanism 2 is placed above the mixing tank 3, and each drug discharge mechanism 7 and the manifold 8 are placed below the mixing tank 3, resulting in a compact layout and saving floor space.
[0030] See Figures 1 to 2 In the above embodiments, each dispensing mechanism 7 includes a first pipe 71, a second pipe 72, and a metering pump 73. The inlet of the first pipe 71 is connected to the outlet of the corresponding stirring chamber 5, the outlet of the first pipe 71 is connected to the inlet of the second pipe 72 through the metering pump 73, and the outlet of the second pipe 72 is detachably connected to the manifold 8.
[0031] In specific implementation, the metering pump 73 can be a plunger-type metering pump, with each plunger-type metering pump having a power of 18.5 kW, a plunger stroke accuracy of ±0.01 mm, and an adjustable displacement of 0-600 liters / hour per pump. The maximum working pressure is 25 MPa, and the flow deviation is calibrated in real time (≤±2%) through a PID algorithm.
[0032] Preferably, the outlet of the second pipe 72 is connected to the manifold 8 via a flange-type quick-release connector 9. In this way, when a certain pipe malfunctions or needs maintenance, only the malfunctioning or maintenance-required pipe needs to be removed, without the need to shut down the entire machine for maintenance. This facilitates maintenance and saves disassembly time, improving the continuity of operations.
[0033] In practical implementation, the flange face of the flange quick-release joint 9 is overlaid with Stellite 6 alloy to improve wear resistance, and the matching metal spiral wound gasket (08Cr18Ni9 + graphite layer) has a leakage rate of ≤1×10^-6Pa·m / s under 25 MPa conditions.
[0034] Preferably, the second pipe 72 and the manifold 8 have a preset angle, which is greater than or equal to 90° and less than 180°. More preferably, the preset angle is 120°, which can reduce pressure drop.
[0035] Preferably, each first pipe 71 is equipped with a viewing mirror, which can be a glass viewing mirror, enabling real-time observation of the fluid state.
[0036] Multiple baffles are arranged horizontally at intervals along the length of the confluence pipe 8. The baffles are arranged in parallel, and each baffle has a damping hole to eliminate pressure pulsation. Specifically, the diameter of each damping hole is 2 to 5 mm.
[0037] The manifold 8 is equipped with check valves 10 and safety valves 11 at intervals. Specifically, the check valve 10 is a dart-type check valve to prevent backflow. The safety valve 11 can be a spring-loaded micro-opening safety valve, which provides instantaneous pressure relief in case of overpressure (response time ≤ 0.1 seconds). Furthermore, the safety valve 11 adopts a dual-spring redundant design (main spring stiffness 50 N / mm, auxiliary spring 30 N / mm) to ensure that the auxiliary spring is opened first to relieve pressure under extreme conditions, thus avoiding overload of the main structure.
[0038] In practice, the manifold 8 is also equipped with a pressure gauge switch 12 for real-time monitoring.
[0039] In practice, the manifold 8 is made of forged 316L stainless steel with a diameter of DN80 mm and a pressure rating of PN250.
[0040] In the above embodiments, the online profile control and drive skid-mounted device further includes a control device and multiple detection devices. Each detection device corresponds one-to-one with each of the first pipes 71, and each detection device is installed in its corresponding first pipe 71. Each detection device is used to detect the flow rate of its corresponding first pipe 71.
[0041] The control device is connected to each detection device and each metering pump 73. The control device is used to adjust the flow rate of the corresponding metering pump 73 according to the flow rate of the first pipeline 71 detected by each detection device. Specifically, the control device provides unified control of each metering pump 73, achieving a flow rate deviation of ≤2% for each channel, thus meeting the requirements for high-dose flow regulation.
[0042] See Figure 1 and Figure 2 Each dispensing mechanism 7 further includes a mixing chamber 74 and two branch pipes 75. The inlets of both branch pipes 75 are connected to a metering pump 73, and the outlets of both branch pipes 75 are connected to the inlet of the mixing chamber 74. The outlet of the mixing chamber 74 is connected to the inlet of the second pipe 72. Specifically, the agent in each mixing chamber 5 is delivered to the first pipe 71 by the metering pump 73. The first pipe 71 delivers the agent to the metering pump 73, which then delivers the agent to the two branch pipes 75. The two branch pipes 75 then deliver the agent to the mixing chamber 74, where the agent is combined and mixed before being delivered to the second pipe 72. The second pipe 72 then delivers the agent to the confluence pipe 8. Thus, by setting up two branch pipes 75 and a mixing chamber 74, a Y-shaped flow distribution structure is formed, reducing turbulence losses. In specific implementation, the inner wall of the branch pipes 75 is electrolytically polished (roughness Ra ≤ 0.8 micrometers).
[0043] See Figures 1 to 2 In the above embodiments, the drug delivery mechanism 2 includes: a connecting pipe 21, a delivery pump 22, and at least two delivery pipes 23. The inlet of the connecting pipe 21 is used to receive the drug, and the outlet of the connecting pipe 21 is connected to the inlet of each delivery pipe 23 via the delivery pump 22. Each delivery pipe 23 corresponds one-to-one with each stirring chamber 5, and the outlet of each delivery pipe 23 is connected to the inlet of the corresponding stirring chamber 5. Each delivery pipe 23 is equipped with a ball valve 13.
[0044] In practice, the inlet of the connecting pipe 21 is connected to the water distribution room 25 to receive the chemicals.
[0045] In practice, each drug delivery pipe 23 is connected to a delivery pipe 24, which is connected to the outlet of the delivery pump 22. Under the action of the delivery pump 22, the drug is delivered from the connecting pipe 21 through the delivery pump 22 to the delivery pipe 24, and then the delivery pipe 24 delivers the drug to each mixing chamber 5 through the respective drug delivery pipes 23. Each drug delivery pipe 23 is positioned above the mixing tank 3, and part of the delivery pipe 24 is positioned above the mixing tank 3, while the other part is determined according to the positions of the delivery pump 22 and the connecting pipe 21; this embodiment does not impose any restrictions on this.
[0046] See Figures 1 to 2In the above embodiments, each stirring device 6 includes a drive motor 61, a stirring shaft 62, and multiple stirring blades 63. The drive motor 61 is mounted on the support device 1 and is located outside the stirring tank 3. The first end of the stirring shaft 62 is also located outside the stirring tank 3 and is connected to the drive end of the drive motor 61. The stirring shaft 62 is rotatably inserted through the stirring tank 3, and the second end of the stirring shaft 62 is located within the corresponding stirring chamber 5.
[0047] Each stirring blade 63 is spaced apart on the shaft of the stirring shaft 62, which is located within the stirring chamber 5. Specifically, each stirring blade 63 is placed within the stirring chamber 5 and is spaced apart along the length of the stirring shaft 62. The length of each stirring blade 63 gradually decreases from the second end of the stirring shaft 62 to the connection point with the stirring tank 3. Specifically, within the portion of the stirring shaft 62 within the stirring chamber 5, the length of each stirring blade 63 gradually decreases from the end of the second end of the stirring shaft 62 to the point where the stirring shaft 62 connects to the stirring tank 3. Preferably, the length of each stirring blade 63 gradually changes from 200 mm to 150 mm from the second end of the stirring shaft 62 to the connection point with the stirring tank 3, forming an axial-radial composite flow field, thereby increasing the mixing efficiency of the reagent by 50% compared to existing single-chamber mixing.
[0048] In specific implementation, each stirring blade 63 includes multiple blades. These blades are evenly arranged along the circumference of the stirring shaft 62, and the first end of each blade is connected to the stirring shaft 62, while the second end of each blade is a free end. Each blade has the same length, which is the distance between its first and second ends, and this length is the same as the length of the stirring blade 63. (Appendix) Figure 2 The attached figure shows only one stirring blade 63. This figure is just an example. In actual implementation, one or more stirring blades 63 can be set according to the actual situation. This embodiment does not impose any restrictions on this.
[0049] As can be seen, in this embodiment, each stirring device 6 has a simple structure and is easy to implement. The stirring blades 63 of the stirring device 6 stir the medicine to ensure that the medicine is mixed evenly.
[0050] In practical implementation, there are three partitions 4, resulting in four mixing chambers 5. Correspondingly, there are four discharging mechanisms 7 and four mixing devices 6. In practical implementation, the mixing shaft 62 and mixing blades 63, driven by a 1.5 kW drive motor 61, generate turbulence at an adjustable speed of 0-200 rpm, ensuring sufficient homogenization of the agent (mixing uniformity CV ≤ 5%), thereby improving the mixing uniformity of the agent by 40%.
[0051] In practice, the waste liquid generated after cleaning the online profile control and drive skid-mounted device can be connected to the treatment system through the waste liquid recovery branch pipe, and the waste liquid can be treated by the treatment system.
[0052] In summary, in this embodiment, the partitions 4 are arranged side by side inside the mixing tank 3, thereby dividing the interior of the mixing tank 3 into at least two mixing chambers 5. The drug delivery mechanism 2 delivers the drug into each mixing chamber 5 within the mixing tank 3. The stirring device 6 in each mixing chamber 5 stirs the drug, ensuring uniform mixing and improving the uniformity of the drug's mixing, thus preventing drug stratification. Furthermore, each mixing chamber 5 is stirred independently, and the partitioned design avoids cross-contamination of the drug. The uniformly mixed drug in each mixing chamber 5 is then discharged through the corresponding drug discharge mechanism 7. The agent is delivered to the manifold 8, which then delivers the agent to the injection well. In this way, the mixing tank 3 is no longer a single-chamber setup as in the prior art, allowing it to hold more agents. The metering pumps 73 in each dispensing mechanism 7 are connected in parallel to increase the pressure, expanding the agent delivery capacity and meeting the needs of large-dose injection. This achieves efficient driving operation. Furthermore, the delivery mechanism 2 is located above the mixing tank 3, while each dispensing mechanism 7 and the manifold 8 are located below the mixing tank 3. This results in a compact layout that saves floor space. At the same time, the lifting ring makes the device easy to lift.
