Description

Technical Field

[0001] This utility model belongs to the technical field of geological engineering development and reservoir evaluation, and specifically relates to a segmented rotating three-dimensional tree-shaped saturated sample holding device for saturated treatment of geological core samples. Background Technology

[0002] In oil and gas geological exploration and reservoir evaluation, fluid saturation of core samples is a crucial preliminary step in obtaining reservoir physical parameters. Reservoir geology focuses on indicators such as rock type, sedimentary environment, pore structure, and fluid saturation capacity. Higher fluid saturation capacity generally indicates well-developed rock fractures and good reservoir performance. Therefore, in source rock analysis and reservoir evaluation experiments, a large number of core samples need to be saturated to meet the requirements of subsequent physical experiments and microscopic tests.

[0003] However, existing saturation devices have limited capacity and can process a small number of samples simultaneously. Furthermore, simply piling samples in the saturation tank can lead to uneven liquid contact, affecting the saturation effect and even damaging some core samples, thus compromising the representativeness and accuracy of the experiment. In addition, conventional saturation devices have a simple structure, are cumbersome to operate, and lack segmented independent holding and stable support functions, failing to meet the needs of simultaneous saturation of large batches and multi-layered samples in the field. Therefore, there is an urgent need to develop a saturation device with a reasonable structure, convenient operation, and the ability to ensure sample independence and saturation uniformity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a segmented rotating three-dimensional tree-shaped liquid saturation sample collection device.

[0005] The technical solution adopted by this utility model is a segmented rotating three-dimensional tree-shaped liquid-filled sample holding device, including a semi-cylindrical cylinder. The cylinder includes a bottom circular plate and a side plate with a semi-circular arc surface. A rigid first pull ring is provided on the upper edge of the side plate. The two ends of the first pull ring are respectively connected to the two ends of the upper edge. Multiple cups are sequentially hinged to one side of the side plate from bottom to top. Each cup contains a rock core sample cup. The bottom surface of the rock core sample cup is provided with several through holes. A fastening cover is hinged to the other side of the side plate. The cup can be rotated to the outside of the cylinder to insert the rock core and liquid, and then rotated back into the cylinder and sealed by the fastening cover around the opening of the cylinder.

[0006] Furthermore, connectors are provided at the upper and lower edges of the cup body to connect with hinge shafts provided on the side of the side plate.

[0007] Furthermore, the fastening cover includes multiple semi-circular stabilizing rings positioned corresponding to the cup body. One end of each stabilizing ring is hinged to the side edge of the side plate, and the other end of each stabilizing ring is fixedly connected to a vertical rod. A rigid second pull ring is provided at the upper end of the vertical rod, and the two ends of the second pull ring are respectively connected to the upper end of the vertical rod and the upper side edge of the fastening cover connected to the side plate.

[0008] Furthermore, the first pull ring and the second pull ring are arc-shaped pull rings of the same size.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model adopts a segmented rotating tree-like arrangement, which allows for layered placement of core samples. The samples are independent and arranged in an orderly manner, avoiding uneven contact and physical damage caused by simple stacking. The cup can be rotated to the outside of the cylinder for placement and removal, making filling, liquid preparation, and saturation operations convenient, reducing labor intensity and improving work efficiency.

[0010] 2. Each core sample cup has a through hole at the bottom to ensure that the solution fully contacts the sample, improve the uniformity of the solution filling, and ensure the reliability of the test data. The cup is fixed in place by a snap-fit ​​cover and a double pull ring limiting structure, which can stabilize the position of the cup after sealing, prevent shaking and tipping during transportation and filling, and ensure the safety of the sample.

[0013] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a segmented rotating three-dimensional tree-shaped liquid-saturated sample-holding device of this utility model.

[0014] like Figure 1 and Figure 2 As shown, a segmented rotating three-dimensional tree-shaped liquid-filled sample holding device includes a semi-cylindrical cylinder 1. The cylinder 1 includes a circular bottom plate and a semi-circular side plate. A rigid first pull ring 2 is provided on the upper edge of the side plate. The two ends of the first pull ring 2 are respectively connected to the two ends of the upper edge. Multiple cups 3 are sequentially hinged to one side of the side plate from bottom to top. Each cup 3 contains a rock core sample cup 4. The bottom surface of the rock core sample cup 4 is provided with several through holes. A fastening cover 5 is hinged to the other side of the side plate. The cup 3 can be rotated to the outside of the cylinder 1 to insert the rock core and liquid, and then rotated back into the cylinder 1 and sealed by the fastening cover 5.

[0015] In this embodiment, three cups 3 are provided inside the cylinder 1, and a core sample cup 4 is provided inside the cup 3, which can ensure that each core sample is independently spaced. Connectors are provided at the upper and lower edges of each cup 3 to connect with the hinge shaft provided on the side of the side plate.

[0016] The fastening cover 5 includes multiple semi-circular stabilizing rings positioned corresponding to the cup body 3. One end of each stabilizing ring is hinged to the side edge of the side plate, and the other end of each stabilizing ring is fixedly connected to a vertical rod. A rigid second pull ring 6 is provided at the upper end of the vertical rod. The first pull ring 2 and the second pull ring 6 are arc-shaped pull rings of the same size. The two ends of the second pull ring 6 are respectively connected to the upper end of the vertical rod and the upper end of the side edge of the fastening cover 5 connected to the side plate. The alignment of the first pull ring 2 and the second pull ring 6 confines the cup body 3 within the cylinder 1, ensuring sample integrity and saturation while maintaining stability and facilitating handling.

[0017] In use, rotate the bottommost cup 3 out separately, and place the rock cores into the rock core sample cup 4 one by one. After placing enough rock cores, add the solution, and then push the rotated-out cup 3 back into the cylinder 1. If there are extra rock cores, perform the above operation on the middle cup 3 until all the rock cores are placed or the three cups 3 are full. Finally, close the locking cover 5, and the first pull ring 2 and the second pull ring 6 at the top are joined together. Then, perform separate vacuum filling. If the sealing conditions can meet the requirements to maintain negative pressure, the solution can be left unadded inside the cup 3.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
