Description

Technical Field

[0001] This utility model relates to the field of liquid preparation device technology, and in particular to a skid-mounted profile control liquid preparation device. Background Technology

[0002] Skid-mounted profile control fluid preparation equipment is a modular, mobile oilfield chemical preparation device used to quickly and efficiently prepare profile control agents (such as polymer gels, particulate suspensions, etc.) and directly inject them into the target well formation.

[0003] Existing solution preparation devices typically prepare solution only once, then inject the prepared profile control agent. After the profile control agent is injected, solution preparation is repeated, which does not allow for continuous solution preparation. This reduces the continuity of profile control agent use and the user experience of the device.

[0004] Therefore, it is necessary to provide a new skid-mounted profile control and liquid preparation device to solve the above-mentioned technical problems. Utility Model Content

[0025] 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.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 4 The present invention provides a skid-mounted profile control and liquid preparation device, which includes a base plate 1.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4A mixing assembly 2 is mounted on a base plate 1, and a feeding assembly 3 is also mounted on the base plate 1. The mixing assembly 2 includes a mixing cylinder 21, two of which are movably mounted above the base plate 1. A mixing paddle 211 is rotatably mounted inside the mixing cylinder 21. The feeding assembly 3 includes a mounting plate 32, which is fixedly mounted at the center of the top of the base plate 1. Electric push rods 321 are fixedly connected to the four corners of the top of the mounting plate 32. The tops of the multiple electric push rods 321 are mounted on the same fixedly connected mounting frame 31, and multiple feeding cylinders 33 are fixedly mounted on the mounting frame 31. A fixedly connected support frame 12 is mounted on the base plate 1. A rotatably connected lead screw 121 is mounted inside the support frame 12. Two threaded support plates 13 are sleeved on the outer wall of the lead screw 121. The inner wall of the support plate 13 is slidably connected to the outer wall of the support rod in the support frame 12, and the top of the support plate 13 is fixedly connected to the mixing cylinder 21.

[0029] It should be noted that by setting up two movable mixing cylinders 21, after the profile control fluid in one mixing cylinder 21 is prepared, it can be moved out from under the feeding assembly 3, so that the other mixing cylinder 21 can be moved to the bottom of the feeding assembly 3. Thus, while the pump body 25 outputs the prepared profile control fluid, the profile control fluid can be prepared simultaneously in the other mixing cylinder 21. Therefore, the device can perform uninterrupted preparation, reducing idle time. When the profile control fluid on one side is used up, the profile control fluid in the other mixing cylinder 21 can be continuously transported, thereby reducing the time when the profile control fluid is interrupted and improving the user experience of the device.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4 Adjustment components 4 are provided at the four corners of the top of the base plate 1. Through holes 11 are provided at the top of the base plate 1 and the opposite parts of the four corners. The adjustment components 4 include a fixing frame 41, and the fixing frame 41 is fixedly installed at the top of the base plate 1 and the opposite part of the through hole 11. A sliding plate 42 is slidably connected on the fixing frame 41. A hydraulic rod 44 is fixedly connected between the top of the sliding plate 42 and the inner top of the fixing frame 41. A universal wheel 43 is fixedly installed at the bottom of the sliding plate 42, and the outer wall specification of the universal wheel 43 is smaller than the inner wall specification of the through hole 11.

[0031] It should be noted that when the device needs to be moved, the hydraulic rod 44 can be extended. The extended hydraulic rod 44 can drive the sliding plate 42 and the caster 43 at its bottom to move downward. When the caster 43 comes into contact with the ground, as the hydraulic rod 44 continues to extend, its force can lift the base plate 1 upward and separate it from the ground, so that the caster 43 can support the device. Therefore, the flexibility of the device in later use and relocation can be improved.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 The bottom end of the feeding cylinder 33 is fixedly connected to the feeding pipe 331. The bottom end of the feeding pipe 331 extends into the interior of the mounting frame 31. A flow meter 332 and a solenoid valve 333 are fixedly installed on the feeding pipe 331. A fixedly connected water supply pipe 34 is inserted into the interior of the mounting frame 31, and the bottom ends of the water supply pipe 34 and the feeding pipe 331 are at the same horizontal plane.

[0033] It should be noted that: by setting the flow meter 332 and solenoid valve 333 on the feed pipe 331, when the raw material inside the feed cylinder 33 is added into the mixing cylinder 21 during use, the flow meter 332 can accurately detect the amount of raw material, thereby making the addition ratio of raw material more accurate.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 4 The top of the mixing cylinder 21 is provided with a threaded cover 22. The inside of the cover 22 is provided with feeding holes 221 at the positions opposite to the feeding pipe 331 and the water supply pipe 34. Above each feeding hole 221 on the top of the cover 22, there are symmetrically distributed sealing half covers 23. The tops of the two corresponding sealing half covers 23 are inclined slope structures. The bottom of the sealing half cover 23 abuts against and slides with the top of the cover 22. A guide frame 231 is fixedly connected to the outer wall of the sealing half cover 23. A sliding support plate 24 is inserted into the outside of the guide frame 231. The bottom end of the support plate 24 is fixedly connected to the top of the cover 22. A spring 232 is fixedly connected between the guide frame 231 and the support plate 24.

[0035] It should be noted that: by setting the sealing half cover 23, after the mixing cylinder 21 moves out from under the feeding component 3, the spring 232 can squeeze the sealing half cover 23 by its own force, so that the sealing half covers 23 on both sides abut against each other to form a complete sealing cover, thereby achieving the sealing of the feeding hole 221.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 4 The bottom of each of the two mixing cylinders 21 is equipped with a pump body 25 for conveying the profile control fluid. The output ends of the two pump bodies 25 are mounted on the same fixedly connected conveying pipe 251. The conveying pipe 251 is a three-way pipe, and valves 252 are provided on the branch pipes on the conveying pipe 251 that are connected to the two pump bodies 25 on both sides.

[0037] It should be noted that by setting the delivery pipe 251 as a three-way pipe and installing a valve 252 on the branch pipe connected to the pump body 25, when the pump body 25 is delivering the profile control fluid, the valve 252 closed on the other side can prevent the delivered profile control fluid from flowing to the other side of the pump body 25, thereby allowing the profile control fluid to be delivered smoothly for use.

[0038] The working principle of the skid-mounted profile control and liquid preparation device provided by this utility model is as follows:

[0039] When using this device, the solenoid valve 333 on the feeding pipe 331 at the bottom of the feeding cylinder 33 can be opened as needed, so that the raw materials can be added into the mixing cylinder 21 through the feeding cylinder 33. During this process, the operator can detect the amount of raw materials added in real time through the flow meter 332, so as to achieve accurate addition of raw materials.

[0040] After the raw materials are added, the mixing paddle 211 in the mixing component 2 can be rotated to stir and mix the raw materials and water. After the raw materials are mixed in proportion, the electric push rod 321 in the feeding component 3 can be extended. The extended electric push rod 321 can drive the top feeding pipe 331 and water pipe 34 to move out of the mixing cylinder 21.

[0041] Then the lead screw 121 can be controlled to rotate, and the rotating lead screw 121 can drive the support plate 13 to move, thereby driving the top mixing cylinder 21 to move, which in turn allows the profile control fluid loaded with the proportioned solution to be moved out from under the feeding assembly 3, so that the empty mixing cylinder 21 on the other side can be moved to under the feeding assembly 3, and the electric push rod 321 can be controlled to retract, so that the feeding pipe 331 and the water supply pipe 34 can be moved downward.

[0042] When the bottom ends of the downward-moving feed pipe 331 and water supply pipe 34 come into contact with the sealing half cover 23, the top of the sealing half cover 23 is an inclined slope, which can transform the vertical downward force of the feed pipe 331 and water supply pipe 34 into a horizontal driving force on the sealing half cover 23. This allows the sealing half cover 23 to release the restriction on the feed hole 221, so that the feed pipe 331 and water supply pipe 34 can be smoothly inserted into the mixing cylinder 21 for the subsequent addition of raw materials and water, and to achieve continuous proportioning of profile control fluid.

[0043] During this process, the pump body 25 can be controlled to work, so as to transport and inject the proportioned profile control fluid through the delivery pipe 251.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
