Description

Background
In general, shale gas is one of natural gas, and is colorless, odorless and gaseous, can not be directly observed by naked eyes, can be recorded by instruments and meters, and can not be intuitively displayed. Therefore, the gas-containing condition of shale can be observed through on-site soaking experiments, in particular, the gas-containing condition in the rock core can be clearly observed through glass by immersing the rock core obtained by drilling into a transparent glass container filled with clear water (if gas is contained, bubbles can emerge from the rock core in the shape of beads or water curtains).
In the immersion experiment, if the observed phenomenon is photographed and recorded, there are problems of light reflection and uneven brightness (for example, the hands of a photographer, a camera, a background object, etc. appear in a photo), and the display effect is affected.

Examples
Referring to fig. 1, fig. 1 is a schematic structural diagram (cross-sectional view) of a shale flooding experiment observation apparatus 10 according to an embodiment of the invention. From fig. 1, it can be seen that a shale flooding experimentation observation apparatus 10 comprises a main body 100, a window shade 120 and a light absorbing layer 130.
Fig. 2 is an assembly schematic diagram of fig. 1, please refer to fig. 1 and 2, from which it can be seen that:
the main body 100, the main body 100 is a cylinder structure with one end open, and one side of the main body 100 away from the opening is provided with a penetrating observation port 101; the side of the main body 100 is provided with a first through hole 110;
a first projection frame 141 and a first illumination device 142;
the first projection frame 141 has a U-shaped cylindrical cross section; the first projection frame 141 is annularly distributed at the periphery of the opening of the main body 100;
an inner wall of the first projection frame 141 forms a receiving chamber having an opening facing away from the main body 100; the first illumination device 142 is completely accommodated in the accommodating chamber in the first projection frame 141.
A window shade 120, the window shade 120 being disposed on the first through hole 110 of the body 100, the window shade 120 being configured to have a movement tendency toward the center of the first through hole 110 to close the first through hole 110.
The inventor finds through research that when the shale gas-containing condition is observed through a soaking experiment, the camera equipment is positioned outside the transparent glass container. During shooting, light from the side of the photographer is reflected on the surface of the glass container and then projected into a video camera (the video camera includes any one of a video camera, a mobile phone and other optical imaging devices), so that the light is received by the video camera to form an image seen by the final photographer. However, these rays from the photographer's side include the relationship of rays from the photographer's body (reflected off of other light sources onto the body, onto glass, and into the camera) and other objects. Thus, there are problems such as "reflection" and uneven brightness (e.g., hands of photographers, cameras, background objects, etc. appear in photographs), which affect the presentation.
Accordingly, the inventors have invented the shale flooding experiment observation apparatus 10, wherein the main body 100 has a cylindrical structure, and the opening of the main body 100 is in contact with the surface of the glass container. When the glass container is used, the camera is placed in the main body 100, an operator enters the main body 100 through the first through hole 110, and light cannot be emitted into the main body 100 from the first through hole 110 because the window shade 120 is arranged, so that the camera can only receive light from a core in the glass container, and cannot receive light reflected by the surface, close to the main body 100, of the glass container, and the occurrence of a reflection phenomenon is improved. I.e., the inner space of the main body 100 becomes a "darkroom" which is advantageous for photographing, thereby improving photographing quality. Meanwhile, the opening of the first projection frame 141 faces away from the main body 100, so that the light emitted by the first illumination device 142 in the first projection frame 141 is directed to the position where the core is placed in a direction away from the main body 100, so as to improve the brightness of the core to be observed, and obtain better shooting illumination conditions. The observation port 101 is used for a photographer to observe the internal condition of the main body 100, thereby completing the photographing task. The shale flooding experiment observation equipment 10 is simple in structure, convenient to operate, capable of obviously improving shooting quality, convenient to manufacture and beneficial to large-scale flow line production.
Alternatively, a holder 140 for placing the image pickup apparatus is provided inside the main body 100.
Alternatively, the window shade 120 includes a plurality of fins 121, and the plurality of fins 121 are rounded radially inward along the circumference of the first through hole 110 to cover the first through hole 110. In this way, when the operator's hand passes through the first through hole 110 to perform photographing work, the window shade 120 can sufficiently shield the space around the hand, thereby improving the problem of excessive light entering the inside of the main body 100.
Fig. 3 is a right side view of the first projection frame 141 in fig. 1, and it can be seen that the first projection frame 141 has a rectangular ring shape. The synergistic effect of the first projection frame 141 and the first illumination device 142 can make the light emitted by the first illumination device 142 deviate from the direction of the main body 100, that is, the light can only be emitted to the position where the core is placed in the glass container connected with the main body 100, so that the illumination in the glass container is lightened, and the darkroom effect of the main body 100 is better.
Alternatively, in the embodiment of the present invention, the radial width of the first projection frame 141 is larger than the radial width of the main body 100. Thus, the photograph taken by the photographer does not have a shadow of the first projection frame 141.
Further, the shale flooding experimental observation apparatus 10 further comprises a light absorbing layer 130, wherein the light absorbing layer 130 is disposed on the inner wall of the main body 100. The light absorbing layer 130 of the inner wall of the main body 100 can effectively absorb light from the photographer side.

The purpose of the first light shielding device 241 and the second light shielding device 242 is to create a good shooting environment for only the light emitted from the periphery of the core to the camera in the sample cabinet 200, so that the interference of the outside is greatly reduced.
As can also be seen, a sample stage 260 of transparent material is provided in the sample cabinet 200. The bottom of the second shade 242 is provided with a latch 250.
