Description

Technical Field

[0001] This utility model relates to the field of cement slurry experimental technology. Specifically, it relates to a high-temperature and high-pressure water loss apparatus. Background Technology

[0002] The high-temperature, high-pressure water loss meter is a commonly used instrument in oil and gas drilling and production laboratories. It is primarily used to measure the water loss of cement slurry under high temperature and pressure conditions. After the measurement, the resulting filter cake needs to be removed for further experimental analysis. Once formed, the filter cake adheres tightly to the filter screen, making it difficult to remove. If the filter cake is not attached to the screen, it can easily detach from the bottom cover, causing difficulties in filter cake collection. Furthermore, the experiment requires the use of numerous bolts for fixation, increasing the operation time. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a high temperature and high pressure water loss instrument, which can be spliced ​​into a complete circular filter screen by means of a No. 1 screen and a No. 2 screen, and can be disassembled when the filter cake is removed, so that the entire filter cake can be completely separated.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] The device includes a frame, with an insulated outer shell on top. An installation hole is located in the center of the insulated outer shell, and a mud cup is mounted on the surface of the installation hole. Threaded openings are located on both the upper and lower sides of the mud cup. A bottom cover is threadedly connected to the bottom of the mud cup. A disassembly mechanism is located below the bottom cover. The disassembly mechanism includes a disassembly bolt, an extension post, and a rotating block. The disassembly bolt is threadedly connected to the bottom cover. A spherical groove is formed on the lower surface of the extension post, and the disassembly bolt is rotatably mounted on the surface of the spherical groove. A limit groove is formed on the upper surface of the bottom cover, and a filter structure is slidably mounted on the surface of the limit groove.

[0006] The technical solution of this utility model has achieved the following beneficial technical effects:

[0007] The design allows the No. 1 and No. 2 meshes to be joined together to form a complete circular filter screen. When removing the filter cake, the No. 1 and No. 2 meshes can be disassembled, allowing the entire filter cake to detach completely. The annular protrusions on the sides of the No. 1 and No. 2 meshes create a ring-shaped anti-detachment mechanism, making it difficult for the filter cake to detach from the top. The spiral-up mechanism of the disassembly bolt allows the extension column to extend upwards. This upward extension causes the rotating block to rotate and press against the No. 1 mesh, stabilizing its position during operation. Simultaneously, it pushes open the through rod, causing it to engage with the fixing hole, thus securing the mud cup to the insulation shell. Attached Figure Description

[0013] This implementation example is attached to the instruction manual. Figure 1-4As shown, two cylinders extend from the top of the frame 1, and an insulating shell 2 is fixed to the cylinders. The insulating shell 2 is equipped with a corresponding heating device. This solution does not improve the heating device, so it is not shown, but this does not mean that the insulating shell 2 does not have it. An installation hole 3 is opened in the middle of the insulating shell 2. The bottom of the installation hole 3 is narrow. The surface of the installation hole 3 can be inserted into a mud cup 4. Threaded openings 5 ​​are opened on both the upper and lower sides of the mud cup 4. The upper threaded opening 5 can be threaded to the top cover, and the lower threaded opening 5 can be threaded to the bottom cover 6. A limiting groove 11 is opened above the bottom cover 6. A filter structure slides on the surface of the limiting groove 11. The filter structure consists of a first mesh 12 and a second mesh 13. The first mesh 12 and the second mesh 13 can be spliced ​​together to form a complete mesh. When removing the mud cake, only the first mesh 12 and the second mesh 13 are needed, and horizontal disassembly allows the mud cake to be removed. The clay cake is completely removed. Annular protrusions 14 are provided on the inner sides of mesh 12 and mesh 13 (annular protrusions 14 are also provided on mesh 13). When the clay cake is formed, it adheres to the annular protrusions 14, thus adapting to them. This makes it difficult for the clay cake to detach from mesh 12 and mesh 13 during movement with the bottom cover 6, ensuring the integrity of the clay cake and making it easy to remove. It also stays on the bottom cover 6 when it is disassembled. To provide stability to mesh 12, reinforcing strips 15 are provided at the joint between mesh 12 and mesh 13. The reinforcing strips 15 are rigid and actually very small. The protrusions are designed to easily identify the position of the reinforcing strips 15. Mesh 12 has round holes on both sides, and mesh 13 is inserted into these holes.

[0014] To ensure the stability of the No. 1 net 12 after installation and to facilitate the fixing of the mud cup 4 to the insulation shell 2, adapter holes 16 are provided on both sides of the bottom cover 6. Below each adapter hole 16 is a threaded shape, and a corresponding threaded groove is provided at the contact point of the disassembly bolt 7. This allows the disassembly bolt 7 to be threaded into the adapter hole 16 (below the disassembly bolt 7 is a hexagonal hole for easy control with a hex wrench). The top of the disassembly bolt 7 has a non-detachable mechanism. As the disassembly bolt 7 is screwed upwards, it drives the extension column 8 to extend upwards. A sealing ring is provided on the surface of the extension column 8 to ensure its sealing. The upward movement of the extension column 8 is as described in the attached instruction manual. Figure 3 The compression causes the rotating block 9 to rotate clockwise (the rotation center of the rotating block 9 faces to the left, and a cylinder is provided on the bottom cover 6 to enable the rotating block 9 to rotate), and it adheres to the top of the first mesh 12. In this way, the first mesh 12 and the second mesh 13 cannot move upward, thus fixing the top of the first mesh 12 and the second mesh 13.

[0015] When disassembling the bottom cover 6, you can first remove the bottom cover 6 without controlling the movement of the disassembly bolt 7. In this way, the bottom cover 6 can be disassembled together with the No. 1 net 12 and the No. 2 net 13.

[0016] As the protruding column 8 extends upwards, it can compress the through rod 18 (the attached diagram shows the already installed bottom cover 6 and disassembly bolt 7 already moved upwards by threads). Because the right side of the compressing rod is inclined, the left side can be inserted into the fixing hole 20 of the mounting hole 3, thus fixing the mud cup 4 and the insulation shell 2, as shown in the attached instruction manual. Figure 3 At this time, the internal spring 19 is in the stretched state. The rod 18 without the extension column 8 will automatically move to the right. The fixing holes 20 in this solution are in a circular array and there are multiple holes. It is also necessary to set corresponding marks (or arrow marks, etc.) on the mud cup 4. Install the mud cup 4 on the heat insulation shell 2 in line with the marks. This will ensure that the fixing holes 20 can appear on one side of the rod 18.

[0017] The control box 21 controls the heating and pressurization equipment of the insulation shell 2, so its electronic components are not displayed.

[0018] An insulating shell 2 is installed on the top of the frame 1. An installation hole 3 is provided in the middle of the insulating shell 2. A mud cup 4 is installed on the surface of the installation hole 3. Threaded openings 5 ​​are provided on both the upper and lower sides of the mud cup 4. A bottom cover 6 is threadedly connected to the bottom of the mud cup 4. A disassembly mechanism is provided below the bottom cover 6. The disassembly mechanism includes a disassembly bolt 7, an extension column 8, and a rotating block 9. The disassembly bolt 7 is threadedly connected to the bottom of the bottom cover 6. A spherical groove 10 is provided on the lower surface of the extension column 8. The disassembly bolt 7 is rotatably mounted on the surface of the spherical groove 10. A limit groove 11 is provided on the upper surface of the bottom cover 6. A filter structure is slidably mounted on the surface of the limit groove 11. The filter mechanism includes a first mesh 12 and a second mesh 13. An annular protrusion 14 is provided on the side wall of the first mesh 12. The middle of the first mesh 12... A reinforcing strip 15 is provided. A rotating block 9 is rotatably mounted on the upper surface of the bottom cover 6. One end of the rotating block 9 contacts an extension post 8. Adaptor holes 16 are provided on both sides of the bottom cover 6. A thread is provided below the adapter hole 16. An extension post 8 is slidably sealed above the adapter hole 16. A through hole 17 is provided at the bottom of the mud cup 4. A through rod 18 is slidably mounted on the surface of the through hole 17. An internal spring 19 is provided on one side of the through rod 18. One side of the through rod 18 is inclined. A fixing hole 20 is inserted into the other side of the through rod 18. The fixing hole 20 is opened inside the mounting hole 3. Round holes are provided on both sides of the first mesh 12. A second mesh 13 is inserted into the surface of the round holes. A control box 21 is provided on one side of the heat insulation shell 2. A top cover 22 is threadedly connected to the upper surface of the mud cup 4.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
