Description

Technical Field

[0001] This utility model relates to the field of mud performance testing technology, specifically to a mud performance testing device for fluorescent seepage prevention walls. Background Technology

[0002] Drilling mud is made by mixing clay and water. Using mud helps prevent borehole collapse, suspends rock cuttings, and allows for safe passage through quicksand layers. Proper use of mud ensures safe drilling. However, excessive use of mud can cause many difficulties in well washing and affect water production. Therefore, when using mud, it is essential to thicken or thin it as needed based on the specific formation properties.

[0003] When using mud, various properties need to be tested, among which the mud permeability test is crucial. Currently, the equipment for testing mud permeability is bulky and complex, and the testing procedures are complicated, making it inconvenient for construction personnel to carry out field tests.

[0004] Therefore, it is necessary to propose a slurry performance testing device for fluorescent anti-seepage walls, which is small in size, simple in structure, easy for construction personnel to carry, and has simple testing procedures, making it convenient for real-time field testing. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a slurry performance testing device for fluorescent anti-seepage walls. It is small in size and simple in structure, making it easy for construction personnel to carry. The testing steps are also simple, facilitating real-time field testing.

[0006] The purpose of this utility model is achieved through the following technical solution: a fluorescent seepage-proof wall mud performance testing device, including an plexiglass tube, one end of which is connected to a pressurizing component, and the other end is connected to a water outlet pipe, which is connected to a measuring cylinder, and the plexiglass tube is filled with a filter layer, a coarse soil layer and mud in sequence from the end away from the pressurizing component to the end near the pressurizing component.

[0007] The pressurization assembly includes a nitrogen cylinder for providing pressure, a gas delivery pipe with its two ends connected to the nitrogen cylinder and one end of an plexiglass tube, respectively, and a pressure regulating valve on the gas delivery pipe.

[0008] One end of the plexiglass tube is detachably connected to a cap that communicates with the pressurization component.

[0009] A ball valve is installed inside the water outlet pipe.

[0010] The filter layer consists of gravel with a particle size ranging from 1 to 1.5 cm.

[0011] The coarse-grained soil layer consists of sand grains with a particle size range of 0.5-1 mm.

[0012] The outlet pipe has at least one point at a height higher than the filter layer.

[0013] It also includes an external frame for supporting the acrylic tubes.

[0014] The water outlet pipe includes a first connecting part communicating with an plexiglass tube and a second connecting part communicating with a measuring cylinder. A hollow telescopic tube with adjustable length and both ends communicating with the first connecting part and the second connecting part is provided between them. The hollow telescopic tube includes a hollow mother tube and a hollow daughter tube that are threaded and rotated together.

[0015] The beneficial effects of this utility model are: Compared to existing technologies, this utility model's mud permeability testing device is smaller in size and simpler in structure, making it easier for construction personnel to carry. Furthermore, the testing procedure is simple, facilitating real-time on-site testing. Additionally, the use of a measuring cylinder allows for the detection of filtration loss, providing a more intuitive observation of the permeability performance of the mud used in the anti-seepage wall.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example 1 See Figure 1 This utility model provides a technical solution: A fluorescent seepage barrier slurry performance testing device includes an outer frame 11. An acrylic tube 1 extending downwards is mounted on the outer frame 11. A detachable cap 10 is attached to the upper end of the acrylic tube 1. An air supply pipe 8 is connected to the cap 10. A nitrogen cylinder 7 is attached to the end of the air supply pipe 8 furthest from the cap 10. A pressure regulating valve 9 is installed on the air supply pipe 8.

[0019] The acrylic tube 1 is filled from top to bottom with a filter layer 4, a coarse soil layer 5, and mud 6. The filter layer consists of gravel with a particle size ranging from 1 to 1.5 cm. The coarse soil layer consists of sand with a particle size ranging from 0.5 to 1 mm. The filter layer 4 is filled to the 250 mark on the acrylic tube 1. The coarse soil layer is filled to the 550 mark on the acrylic tube 1.

[0020] A water outlet pipe 2 is connected to the lower end of the plexiglass tube 1. The water outlet pipe 2 is fixed to the side of the outer frame 11 by a hook 17. The upper end of the water outlet pipe 2 is horizontally higher than the water filter layer 4 to prevent water in the water filter layer from affecting the experimental results. A measuring cylinder 3 is connected to the other end of the water outlet pipe 2. A ball valve is installed inside the water outlet pipe 2.

[0021] Test Procedure The filter layer 4 and coarse soil layer 5 are sequentially filled to the corresponding height inside the plexiglass tube 1. A water pipe is used to connect the funnel to the water outlet pipe 2 below the plexiglass tube 1, and the soil is stably and slowly saturated in the reverse direction using the principle of communicating vessels.

[0022] Using a syringe with a water tube, slowly inject the mud into the 6 to 750 mark along the side wall of the plexiglass tube 1.

[0023] Close the system, pressurize it to 0.4 MPa, open the ball valve switch, start the test, and record all data.

[0024] Close the ball valve switch to release the air pressure, pour out the mud 4, coarse soil layer 5 and filter layer 4, clean the device, and end the test.

The hollow telescopic pipe 14 includes a hollow mother pipe 15 and a hollow daughter pipe 16 that are threaded and rotatably connected to each other.

[0026] When it is necessary to adjust the height of the second connecting part 13 to be higher than the filter layer 4, one hand can be used to hold the hollow mother tube 15 while the other hand can be used to rotate the hollow daughter tube 16, thereby raising the height of the second connecting part 13. After the height of the second connecting part 13 is adjusted, it can be connected to the measuring cylinder 3.
