Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a mud permeation formation simulation device, comprising: a support mechanism 1, including a support frame assembly 11, a group of collecting dish assemblies 12 and a timer 13 arranged on the support frame assembly 11; a formation permeation simulation mechanism 2, including a group of transparent tube assemblies 21 embedded in the support frame assembly 11, and a filter plate 22 slidably embedded in the group of transparent tube assemblies 21; a group of mud storage mechanisms 3 arranged on the support frame assembly 11;

[0022] Among them, the samples collected from different strata are poured into a group of transparent tube assemblies 21 respectively, and the samples can be blocked by the filter plate 22 to prevent the samples from falling. A group of mud storage mechanisms 3 are opened and the timer 13 is controlled to work at the same time. The equal amount of mud in the mud storage mechanism 3 is injected into a group of transparent tube assemblies 21 respectively. After the mud penetrates the sample, it will flow into a group of collecting dish assemblies 12 respectively. When the collecting dish assembly 12 reaches the specified depth, the corresponding timer 13 is closed. The penetration speed of the mud in the sample can be judged by time comparison. After the simulation experiment is completed, the transparent tube assembly 21 is removed and inverted to enable the filter plate 22 and the sample to be discharged together, thereby facilitating the staff to clean it. When pressurization is required, the cover plate sealing card connected to the pressurizing device is embedded in the transparent tube assembly 21, and the pressurization operation of the transparent tube assembly 21 can be realized through the pressurizing device.

[0023] Specifically, the transparent tube assembly 21 includes a transparent tube body 211, a scale bar 212 is arranged on the outside of the transparent tube body 211, an outer clamping ring 213 is fixedly connected to the outer side of the transparent tube body 211 near the upper end, and an inner retaining ring 214 is fixed inside the transparent tube body 211 near the lower end.

[0024] Specifically, the mud storage mechanism 3 includes a storage tank 31 , an inlet pipe 32 is fixedly connected to the upper side of the storage tank 31 , an outlet pipe 33 is fixedly connected to the lower end of the storage tank 31 , and an electromagnetic valve 34 is fixedly connected to the outer side of the outlet pipe 33 .

[0025] Specifically, the filter plate 22 is slidably embedded in the transparent tube body 211 , the filter plate 22 is located on the upper side of the inner retaining ring 214 , and the outlet pipe 33 is located on the upper side of the transparent tube body 211 .

[0026] As can be seen from the above, the filter plate 22 can be limited by the inner retaining ring 214, the sample can be limited by the filter plate 22, and the sample volume depth can be controlled by the scale bar 212, so that the depth of different samples can be kept consistent. Mud water can be stored by the storage tank 31, and the mud water in the storage tank 31 can be introduced into the transparent tube body 211 through the outlet pipe 33 by opening the solenoid valve 34.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the support frame assembly 11 includes a support frame body 111, on which a group of limit clamp frames 112 and a support plate 113 are fixedly connected; the collecting dish assembly 12 includes a collecting dish body 121, on the outer side of which a scale bar 122 is provided.

[0028] Specifically, the storage tank 31 is embedded in the support plate 113 , and the transparent tube body 211 is embedded in the limiting clamping ring frame 112 through the outer clamping ring 213 .

[0029] As can be seen from the above, the storage tank 31 can be supported by the support plate 113, and the outer clamping ring 213 can be supported by the limiting clamping ring frame 112, so that the transparent tube body 211 is fixed, and the depth of the mud water in the collecting dish body 121 can be read through the scale bar 122, so as to facilitate comparison.
