Description

Technical Field

[0001] This application relates to the field of microscopic visualization experimental research equipment technology, and more specifically, to a clamp-type seepage model for microscopic visualization of ultra-low permeability reservoirs. Background Technology

[0002] As an important successor area for global oil and gas resource development, research on the seepage mechanism of ultra-low permeability reservoirs has long been constrained by the observational limitations of traditional physical models. In order to conduct efficient research on ultra-low permeability reservoirs, researchers often use clamp-type seepage models that visualize the microscopic structure of ultra-low permeability reservoirs.

[0003] The prior art publication CN210264653U provides a microscopic seepage experimental apparatus. This apparatus ensures the positional stability of the injection tube relative to the clamping frame by using an injection tube and a clamping frame. At the same time, by setting a sealing gasket, it ensures the sealing of the connection between the injection tube and the injection port to prevent fluid leakage. A transparent bracket is used to support the two clamping frames and the microscopic visual model between the two clamping frames, which facilitates convenient observation of the microscopic visual model.

[0004] While the existing technical solutions described above can improve the convenience of observing microscopic visual models to some extent, they still have the following drawbacks: the microscopic visual models in these solutions are fixed in a designated position, making it difficult for researchers to adjust their position, thus hindering the simulation of seepage in oil layers at different angles. Therefore, we propose a clamp-type seepage model for microscopic visualization of ultra-low permeability reservoirs. Utility Model Content

Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a clamping-type seepage model for microscopic visualization of ultra-low permeability reservoirs, comprising: an operating table 1, a clamping frame 3 installed above the operating table 1, a microscopic visible seepage model 12 detachably installed inside the clamping frame 3, a lifting rod 14 installed on the other side of the operating table 1, a microscope 16 fixedly installed on one side of the lifting rod 14, a receiving plate 2 installed on the operating table 1, a rotating frame 4 rotatably connected to the receiving plate 2, the clamping frame 3 being constrained by and rotatably connected to the rotating frame 4, and an adjustment mechanism installed on one side of the clamping frame 3 for driving the clamping frame 3 to rotate.

[0023] A limiting groove 401 is provided inside the rotating frame 4. A connecting rod 5 is provided inside the limiting groove 401 to limit the rotation. The clamping frame 3 is connected and fixed to the connecting rod 5.

[0024] The adjustment mechanism includes an electric push rod 11, with a rack 10 fixedly connected to the output end of the electric push rod 11. A drive gear ring 6 is fixedly installed on the lower side of the clamping frame 3. The drive gear ring 6 has an arc-shaped structure, and the rack 10 is meshed with the drive gear ring 6.

[0025] When observing the microscopic visible seepage model 12, if it is necessary to observe the seepage situation at different angles, the rack 10 moves to one side under the action of the electric push rod 11. Since the rack 10 is engaged with the drive gear ring 6, the drive gear ring 6 drives the clamping frame 3 and the microscopic visible seepage model 12 to rotate to one side. Then, the staff can observe the seepage model 12 in this state through the microscope 16. In this way, the staff can easily and quickly adjust the microscopic visible seepage model 12 to the designated position, which facilitates the simulation of the seepage situation of the oil layer at different angles and effectively ensures the experimental results.

[0026] Reference Figure 3 The drive gear ring 6 has a scale value 8 on one side, and an indicator needle 9 is fixedly installed on the receiving plate 2 to facilitate the user to observe the rotation angle of the microscopic visible seepage model 12.

[0027] Reference Figure 1 and Figure 3 The receiving plate 2 is rotatably connected to the operating table 1. A drive gear 7 is fixedly sleeved on the outer side of the receiving plate 2. An electric motor 13 is installed on one side of the operating table 1. A drive gear 15 is fixedly connected to the output end of the electric motor 13. The drive gear 15 is meshed with the drive gear 7.

[0028] During the observation of the microscopic visible seepage model 12, the motor 13 runs. Since the drive gear 15 is engaged with the driving gear 7, the receiving plate 2 drives the clamping frame 3 and the microscopic visible seepage model 12 to rotate around the axis of the receiving plate 2. This allows the staff to make further adjustments to the microscopic visible seepage model 12, which is beneficial for the staff to observe the microscopic visible seepage model 12 in detail.

[0029] This application, by setting up a rotating frame 4 and an adjustment mechanism, enables staff to easily and quickly adjust the microscopic visible seepage model 12 to a designated position, thereby facilitating the simulation of oil layer seepage at different angles and effectively ensuring experimental results. At the same time, by setting up a moving gear 7, a motor 13, and a drive gear 15, staff can further adjust the microscopic visible seepage model 12, which is beneficial for staff to conduct detailed observation of the microscopic visible seepage model 12.

[0030] The implementation principle of the clamp-type seepage model for microscopic visualization of ultra-low permeability reservoirs in this application embodiment is as follows: When relevant personnel need to use this technical solution for experiments, if it is necessary to observe the seepage situation at different angles, under the action of the electric push rod 11, the rack 10 moves to one side, driving the gear ring 6 to rotate the clamping frame 3 and the microscopic visible seepage model 12 to one side until the indicator needle 9 points to the appropriate scale value 8. Then, the personnel can observe the seepage model 12 in this state through the microscope 16. During the observation of the microscopic visible seepage model 12, the motor 13 runs, and the receiving plate 2 will drive the clamping frame 3 and the microscopic visible seepage model 12 to rotate around the axis of the receiving plate 2, which facilitates further adjustment of the microscopic visible seepage model 12. By continuing in this manner, the experiment can be completed.
