Description

Technical Field

[0001] The utility model relates to the technical field of graduated cups, in particular to a reflective graduated cup with visual effects. Background Art

[0002] Lost circulation is a common and complex downhole accident in oil drilling, cementing, and downhole operations. Due to differences in the mechanisms and morphologies of leakage channels, the plugging materials and technologies used vary. To verify the effectiveness of plugging materials and develop more effective plugging solutions, simulation test devices are needed to simulate the downhole environment and leakage channels. Traditional plugging simulation devices often suffer from insufficient functionality, inconvenient operation, and low test accuracy, making them unable to meet the requirements of modern drilling technology for plugging material evaluation.

[0003] The traditional sand bed plugging simulation test device is to pour the 20-40 mesh filter sand of the 350cm sealing top cover 3 into a cylindrical transparent drilling fluid cup with a filter screen at the bottom, and then pour 500cm of drilling fluid from the upper part of the cup. The air source is connected to adjust the pressure to 0.69MPa, and the plugging ability of the drilling fluid system on the pores formed in the filter sand under the pressure difference of 0.69MPa is measured. The black scale reading value printed on the transparent cup reflects the penetration of the drilling fluid into the filter sand at the bottom of the cup. The smaller the sedimentation height of the drilling fluid penetrating into the filter sand, the stronger the drilling fluid plugging effect, and vice versa. However, after many tests, the scale on the drilling fluid cup was severely worn, and the dark brown color of the drilling fluid interfered with the scale reading, making it difficult to read the scale during the experiment or even incorrectly, affecting the accuracy of the detection. Therefore, corresponding improvements are needed. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reflective scale cup with a visual effect, comprising a drilling fluid see-through cup body, a cup bottom cover, and a sealed top cover, wherein the bottom of the drilling fluid see-through cup body is connected to the cup bottom cover, and the top of the drilling fluid see-through cup body is connected to the sealed top cover;

[0013] Preferably, the first reflective scale is a scale display for the amount of filter sand injected, and the second reflective scale is a scale display for the amount of mud injected.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the reflective scale cup with visual effect not only has a visual display effect, but also has an illumination function to assist reading to ensure the accuracy of observation, and effectively protects the reading scale to avoid wear after repeated use, and the drilling fluid transparent cup body is high in strength and not easy to be damaged;

[0015] Inject the filter sand from the top of the drilling fluid perspective cup into the drilling fluid perspective cup, and make the filter sand above the bottom filter screen to the reflective scale position 1, then inject an appropriate amount of drilling fluid into the filter sand in the drilling fluid perspective cup to the reflective scale position 2, then cover the sealing top cover on the drilling fluid perspective cup, use the top cover sealing ring to seal the drilling fluid perspective cup, and use the air inlet pipe to inject air into the drilling fluid perspective cup, and use the display of the drilling fluid perspective cup to observe the drilling fluid penetration and blocking situation.

[0026] See also Figure 1-Figure 5 , the utility model provides the following technical solutions: Example 1

[0027] In order to solve the problem that the reflective scale of the existing reflective scale cup is easily worn and damaged as the number of uses increases, thus affecting the detection effect, the following technical solutions are announced. For details, please refer to Figure 1 、 Figure 2 、 Figure 3A reflective scale cup with a visual effect includes a drilling fluid perspective cup body 1, a cup bottom cover 2, and a sealed top cover 3. The bottom of the drilling fluid perspective cup body 1 is connected to the cup bottom cover 2, and the top of the drilling fluid perspective cup body 1 is connected to the sealed top cover 3. The bottom end of the sealed top cover 3 is evenly provided with mounting grooves 13, and the interior of the mounting grooves 13 is connected to a light strip 14, and one side of the light strip 14 is connected to an adhesive strip, and the light strip 14 is detachably connected to the mounting groove 13 through the adhesive strip. It also includes: a reflective scale 9 is provided on the lower left side of the drilling fluid perspective cup body 1, a reflective scale 2 10 is provided on the upper right corner of the drilling fluid perspective cup body 1, and a reflective scale 10 is provided on the upper right corner of the drilling fluid perspective cup body 1. The scale 1 (9) is for the filter sand injection amount, and the scale 2 (10) is for the mud injection amount. The outsides of the reflective scale 1 (9) and the reflective scale 2 (10) are coated with a reflective scale protective coating 11. The reflective scale protective coating 11 is a soft transparent coating made of polytetrafluoroethylene. The bottom end of the sealing top cover 3 is connected to the top cover sealing ring 5. The top of the sealing top cover 3 is provided with a mounting hole 301, and the interior of the mounting hole 301 is penetrated by an air intake pipe 8. The top of the cup bottom cover 2 is connected to a lower sealing block 4, and the lower sealing block 4 is made of rubber. The bottom end of the cup bottom cover 2 is connected to a filter loss pipe 7. The bottom end of the inside of the drilling fluid perspective cup body 1 is connected to a bottom filter screen 6.

Then, the filter sand is injected into the drilling fluid perspective cup body 1 from the top of the drilling fluid perspective cup body 1, and the filter sand is placed above the bottom filter screen 6 to the reflective scale 9 position. Then, an appropriate amount of drilling fluid is injected into the filter sand in the drilling fluid perspective cup body 1 to the reflective scale 10 position, and then the sealing top cover 3 is covered.

In order to improve the safety and reliability, a reflective scale protective coating 11 is further coated on the reflective scale 1 9 and the reflective scale 2 10. The reflective scale protective coating 11 is a soft transparent coating with good adhesion and flexibility, so that it can be tightly adhered to the reflective scale 1 9 and the reflective scale 2 10 to form an effective protective film. The transparent property does not affect the visibility of the reflective scale 1 9 and the reflective scale 2 10, thereby ensuring the durability of the reflective scale 1 9 and the reflective scale 2 10, and ensuring clear scales and accurate readings.
