The working principle of the device is described in detail below:

The bottle body 1 is used for storage, experiments and visual observation of the gel under high temperature and sealing conditions. For example, the bottle body 1 can be a transparent glass bottle with a large opening, and the bottle body 1 and the cover body 2 can be connected through a transparent glass bottle. Threaded connection for easy disassembly. Specifically, the bottle body 1 may be provided with a lower buckle ring, and the lower buckle ring is buckled and mounted on the bottle body 1 and is connected with the cover body 2 by threads. Caps can be made of type 316 stainless steel to maintain stiffness under experimental conditions.

The process of using the device to extract the gas in the bottle body 1 can be: open the stop valve 4, so that the bottle body 1, the first pipe body 3, the stop valve 4, the buffer bottle 5 and the vacuum pump 6 are in a connected state, and the vacuum pump 6 is in a state of communication. A pressure gauge can be provided, the vacuum pump 6 is turned on, and the gas in the bottle body 1 is extracted. When the pressure gauge shows that the gas pressure in the bottle body 1 is less than 0MPa, it indicates that the bottle body 1 is in a vacuum state, close the stop valve 4, and then Turn off the vacuum pump 6 and stop pumping. The buffer bottle 5 and the shut-off valve 4 are disassembled, so that the gel-filled bottle 1 can be heated for subsequent experiments.

After heating, the shut-off valve 4 can be opened to release the pressure, and then the cover body 2 can be opened to take out the gel sample for testing. When cleaning the device, the remaining gel sample is introduced into the waste liquid bucket, and the cover body 2, the first tube body 3 and the stop valve 4 can be cleaned as a whole.

Through the vacuum pump 6 , the buffer bottle 5 , the stop valve 4 and the first pipe body 3 , after the gel to be detected is contained in the bottle body 1 , the gas in the bottle body 1 can be extracted, so that the bottle body 1 is in a vacuum state , and then heat the device, that is, to make the gel in the bottle body 1 under the same high temperature and oxygen-free environment as the stratum state, and then detect the gel in the bottle body 1 . After each test, the device is repeatedly used to extract the air in the bottle body 1 to maintain the same test environment as the formation state, so that the gel is not oxidized by the air during the entire test process, and the accuracy of the test results is improved.

Specifically, the first through hole can be opened concentrically with the cover body 2, and the diameter can be set as required, for example, can be 10 mm. The outer wall of the cover body 2 may be provided with anti-slip patterns for easy screwing. For example, the anti-slip patterns may be vertical patterns.

The structure and working principle of each part of the device are described in detail below:

That is, the lower end of the first tube body 3 is U-shaped, so that the port of the first end is upward, and the liquid level of the gel does not exceed the first end during the process of adding gel to the inside of the bottle body 1. For example, the liquid level can be made 1 cm lower than the port at the first end, so as to avoid pulling the gel out of the bottle 1 during the pumping process, avoiding the loss of the gel or damaging the vacuum pump 6 .

Specifically, the bend may be formed by connecting two right-angle bends, or other structures, which are not limited in this embodiment.

In a possible design, the shut-off valve 4 is a right-angle shut-off valve 4, the first opening of the right-angle shut-off valve 4 is arranged downward, and the second opening is arranged horizontally.

The second end of the first pipe body 3 is connected to the first opening of the right-angle stop valve 4 , and the second opening is used to connect the buffer bottle 5 to facilitate the installation and placement of the buffer bottle 5 .

The angle between the axes of the two openings of the right-angle stop valve 4 is 90 degrees, so that there is no mutual influence between the installation and removal of the two openings, and it is avoided when the buffer bottle 5 is removed from the stop valve 4. The connection between an opening and the first tube body 3 becomes loose, so that air enters the bottle body 1 to ensure the suction effect.

In a possible design, a sealing ring 7 is further provided between the bottle body 1 and the bottle cap; the sealing ring 7 is provided with a second through hole adapted to the first tube body 3 . The second through hole of the sealing ring 7 and the first tube body 3 are connected by interference to play a sealing role; the sealing ring 7 also plays a sealing role between the bottle body 1 and the bottle cap to prevent gas from entering in bottle 1.

Specifically, the sealing ring 7 may be made of high temperature resistant rubber material.

In a possible design, the sealing ring 7 is glued to the inner wall of the cover body 2 . To avoid falling off, specifically, the first tube body 3 and the cover body 2 can be installed first, and then the sealing ring 7 is bonded. The outer edge of the sealing ring 7 is in close contact with the inner wall of the cover body 2, and the bottom surface is used for Sealing with the bottle body 1 is achieved.

In a possible design, the buffer bottle 5 includes: a steel bottle 51, a second tube body 52 and a third tube body 53; the first end of the second tube body 52 is inserted into the steel bottle 51, and the second end communicates with the steel bottle 51 Stop valve 4; the first end of the third pipe body 53 is inserted into the cylinder 51, and the second end is connected to the vacuum pump 6; the first end of the third pipe body 53 is higher than the first end of the second pipe body 52 end.

Based on the above design, even if part of the gel is sucked into the cylinder 51 and deposited at the bottom of the cylinder 51 , it will not be sucked into the vacuum pump 6 through the third pipe body 53 , thereby protecting the vacuum pump 6 . The shape of the main body of the steel cylinder 51 can be designed as required, for example, it can be a cylinder, a rectangular parallelepiped, etc., which is not limited in this embodiment.

In a possible design, a transparent observation window 511 is provided on the side wall of the steel cylinder 51 . Used to see if any gel is drawn into the buffer bottle 5.

In a possible design, the second pipe body 52 and the shut-off valve 4 are connected by a screw thread, which is convenient for assembly and disassembly.

In a possible design, the first pipe body 3 and the shut-off valve 4 are connected by a screw thread, which is convenient for assembly and disassembly. Specifically, the second end of the first pipe body 3 has an external thread, which is connected with a matching internal thread on the stop valve 4 .

In a possible design, the first tube body 3 is welded on the cover body 2 . The structure is stable and the sealing effect is good.
