Description

Technical Field

[0001] The utility model relates to the technical field of shale organic carbon content detection, in particular to a detection device for shale organic carbon content detection. Background Art

[0002] Currently, unconventional energy, especially shale gas, has become a key focus of oil and gas extraction research. Extensive mining practices have shown that shale gas is primarily stored in low-porosity, low-permeability, organic-rich shale layers. The organic matter content has a significant impact on shale gas storage and extraction. Hydrocarbons and other organic matter in geological bodies are primarily composed of carbon and hydrogen. The organic carbon content in rocks accurately reflects the abundance of organic matter and is an important basic indicator for evaluating the organic matter abundance and sedimentary environment of source rocks. It has long been widely used in oil and gas geological exploration. An organic carbon analyzer is an instrument used to measure total organic carbon in a solution. Its measurement principle is to oxidize organic carbon in a solution into carbon dioxide. After eliminating interfering substances, the carbon dioxide content is measured by a detector. The corresponding relationship between carbon dioxide and total organic carbon is used to quantitatively determine the total organic carbon in the solution. Currently, the organic carbon content of shale is usually tested by adding the sample to a crucible, placing it in a beaker, and then adding 5% hydrochloric acid to react and remove the inorganic carbon in the sample. After the reaction is complete, the crucible is removed and placed on a filter rack or porcelain plate and rinsed with water to remove the hydrochloric acid. After all the hydrochloric acid is washed away, the crucible and sample are dried before being tested on the machine. Not only does this take a long time, but the experimental error is large, and the test results are inaccurate and unreliable.

[0003] In the existing patent application with application number CN202222251159.3, a detection device for detecting the organic carbon content of shale is proposed. Although the device is coordinated by base one, base two, frame one, shell, shell cover, crushing assembly, mounting assembly, short block, fixing assembly, frame two, acid burette, alkaline burette, magnetic stirrer, beaker, organic carbon analyzer body and stirring magnet, the detection time is shortened, the error is reduced, and the accuracy of the test results is improved. However, when the shale block is crushed, the process of removing the crushed shale is relatively cumbersome. It is necessary to manually remove the shell cover from the shell first, and then rotate the turntable two to rotate and move the screw rod two, so that the right end of the screw rod two is separated from the short tube, and then the shale powder in the shell can be poured into the beaker. This process takes a long time, which will reduce the efficiency of shale organic carbon content detection, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a detection device for detecting the organic carbon content of shale includes a workbench 1, a crushing device 3, a weighing device 4, and an organic carbon analyzer 5. The weighing device 4 and the organic carbon analyzer 5 are placed on the upper end of the workbench 1. The upper end of the workbench 1 is fixedly installed with a mounting bracket 2. The mounting bracket 2 consists of a mounting base plate 6, an L-shaped connecting plate 7, and a mounting connecting ring 8. The L-shaped connecting plate 7 is fixedly installed on the upper end of the mounting base plate 6. The mounting connecting ring 8 is fixedly installed on one end of the L-shaped connecting plate 7. The crushing device 3 is fixedly installed on the mounting connecting ring 8. The crushing device 3 consists of a top base plate 9. , a feed hopper 10, a main body shell 11, a blocking filter 12, a conical cylinder 13, a drive motor 14, a crushing shaft 15 and a crushing blade 16. The feed hopper 10 is fixedly inserted on the top base plate 9, the main body shell 11 is fixedly mounted on the lower end of the top base plate 9, the blocking filter 12 is fixedly mounted on the lower side of the inner wall of the main body shell 11, the conical cylinder 13 is fixedly mounted on the lower end of the main body shell 11, the drive motor 14 is fixedly mounted on the upper end of the top base plate 9, the crushing shaft 15 is fixedly mounted on the output shaft of the drive motor 14, and the crushing blade 16 is fixedly mounted on the crushing shaft 15. When testing the organic carbon content of shale, first use the weighing device 4 to weigh the beaker, and then place the beaker directly under the crushing device 3. Then, put the shale sample into the crushing device 3, and then start the drive motor 14 on the crushing device 3, so as to use the drive motor 14 to drive the crushing shaft 15 and the crushing blade 16 to crush the shale sample. Then, the crushed shale sample will pass through the mesh of the blocking filter 12 under the influence of gravity and fall into the beaker below. Then, use the weighing device 4 to weigh the beaker containing the shale powder, and then add the solvent into the beaker. The solvent and shale powder are stirred to dissolve the shale powder in the solvent. Then, phenolphthalein reagent and excess acid are added to the beaker to discharge the carbon element in the carbonate contained in the shale in the form of carbon dioxide to avoid affecting the test results of the organic carbon analyzer 5. When the color of the solution in the beaker is red, stop adding the acid, and then add alkaline solution to neutralize the excess acid. When the color of the solution in the beaker is colorless, the neutralization is completed. Then, the solution in the beaker is placed in the organic carbon analyzer 5 for detection. According to the test results and the mass of the shale powder when weighed, the corresponding calculation is made to obtain the content.

[0021] Furthermore, the mounting base 6 on the mounting bracket 2 is fixedly mounted on the upper end of the workbench 1 , and the mounting bracket 2 can support the crushing device 3 , so that the crushing device 3 is at a certain distance from the workbench 1 , so that a beaker can be placed under the crushing device 3 .

[0022] Furthermore, the main body shell 11 on the crushing device 3 is a cylindrical structure, and the main body shell 11 is fixedly inserted into the mounting connection ring 8 on the mounting bracket 2. The crushing shaft 15 on the crushing device 3 passes downward through the top base plate 9. The crushing blade 16 on the crushing device 3 is located in the main body shell 11, and the crushing blade 16 is close to the upper end of the blocking filter 12. The mesh diameter of the blocking filter 12 needs to be similar to the size of the required shale powder. When crushing the shale sample, the shale can be placed in the main body shell 11 through the feed hopper 10. Finally, under the action of gravity, the shale sample falls on the upper end of the blocking filter 12. When the drive motor 14 is started, the drive motor 14 will drive the crushing blade 16 on the crushing shaft 15 to rotate at a high speed, so that the crushing blade 16 can break the shale on the upper end of the blocking filter 12. Then, the shale powder smaller than the mesh diameter of the blocking filter 12 will pass downward through the mesh of the blocking filter 12 under the influence of gravity. Finally, the shale powder will pass downward through the conical cylinder 13, and finally the shale powder will fall into the beaker directly below the conical cylinder 13.
