Description

Technical Field

[0001] The utility model relates to a physical property measurement device for quickly and efficiently measuring the density parameters of rock cores, belonging to the technical field of rock core measurement. Background Technique

[0002] A rock core is a cylindrical rock sample taken from a borehole using a rock core ring bit and other coring tools according to the needs of geological work or engineering. An ore core is a mineral-bearing rock or ore taken from an ore body or ore layer of a solid mineral deposit. Rock cores are important physical materials for studying and understanding underground geology and mineral conditions. During the exploration and development of oil and gas fields, coring tools are lowered into the well according to the stratigraphic horizons and designed depths obtained from exploration, and the drilled rock samples are taken. Rock cores are the most intuitive and practical data for understanding underground oil layers and the characteristics of the contained fluids. There are two methods of taking rock cores from the well wall and drilling coring, usually the latter is the main method.

[0003] At present, when measuring the density parameters of rock cores, a balance is often used to weigh the rock cores, and a graduated cylinder is used to measure the volume of the rock cores by the water displacement method. During the process of taking out the rock cores from the graduated cylinder, the water in the graduated cylinder will be lost, and a burette is needed to add water in the graduated cylinder to a fixed scale before the measurement of the next rock core can be carried out. The process is rather cumbersome, which has brought certain adverse effects to the actual use. Therefore, improvement is needed. Content of the Utility Model

The bottom of the inner wall of the dust-proof measurement box abuts against a water storage and measurement frame. A limiting sleeve plate is fixedly connected to the top of the water storage and measurement frame. A suspended lifting ball rod is slidably connected to the inner wall of the limiting sleeve plate. An induction plate is fixedly installed at the top of the suspended lifting ball rod. A distance sensor is fixedly connected to the side of the inner wall of the dust-proof measurement box, and the distance sensor is directly above the induction plate. A waterproof marking lamp is fixedly installed at the front side of the bottom of the suspended lifting ball rod. A transparent measurement scale is connected to the front side of the water storage and measurement frame, and the in-body measurement scale is directly in front of the waterproof marking lamp.

[0007] Further, the limiting component includes a limiting plate and a limiting groove. The limiting plate is fixedly connected to the side of the threaded sleeve plate. The limiting groove is opened on the rear side of the inner wall of the dust-proof measurement box. The inner wall of the limiting groove and the surface of the limiting plate are slidably connected.

[0008] Further, the locking component includes a magnetic adsorption locking plate and a magnetic adsorption locking sleeve. The magnetic adsorption locking plate is fixedly connected to the top of the weighing and placing frame. The magnetic adsorption locking sleeve is fixedly connected to the bottom of the threaded sleeve plate. The inner wall of the magnetic adsorption locking sleeve and the surface of the magnetic adsorption locking plate are magnetically clamped and adapted.

[0009] Further, the main body of the weighing and placing frame is a smooth drainage frame with a front opening. A lifting plate is placed on the top of the smooth drainage frame. A driving motor 2 is fixedly installed inside the lifting plate. The output end of the driving motor 2 and the top of the smooth drainage frame are fixedly installed.

[0010] Further, a weighing sensor is fixedly installed at the bottom of the inner wall of the smooth drainage frame. The top of the weighing sensor is connected to a drainage net frame with a placement platform. A drainage flow groove is opened on the side of the smooth drainage frame.

[0011] Further, a sliding plate is fixedly connected to the top of the smooth drainage frame.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the internal weighing placement frame of the dust-proof measurement box can be used to place core materials. That is, in the smooth drainage frame inside the weighing placement frame, the core materials can be placed on the inner wall of the drainage mesh frame for stable placement.

That is, the general liquid level change record in the water storage measurement frame. The water level in the water storage measurement frame will float upward to drive the floating lifting ball rod to adjust the height. The floating lifting ball rod can be limited and guided to move in the limiting sleeve plate. Under the induction of the induction plate and the distance sensor, the change in the distance is sensed. And the distance change record of the left and right induction plates can be recorded when the distance change between the two induction plates is stable and the same. And a waterproof marking lamp is provided at the front side of the bottom of the floating lifting ball rod. Under the marking of the transparent measurement scale, a secondary observation record is made to avoid the situation that the water cannot completely penetrate during the observation of the core materials entering the water. The driving motor 2 can be operated to drive the smooth drainage frame to rotate. Under the action of the sliding plate and the annular groove, the smooth drainage frame can rotate smoothly, shake the water penetrated into the core materials, and then lift the weighing placement frame upward and rotate the smooth drainage frame to drain the liquid into the inside of the water storage measurement frame to ensure the recovery of the liquid level in the water storage measurement frame, and the liquid level volume of the core materials can be quickly and efficiently measured.

[0024] Example 1 Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0025] A physical property measurement device for quickly and efficiently measuring core density parameters, including a dust-proof measurement box 1 with a switchable door.

[0026] Specifically, as Figures 1 - 5 shown, the limiting component includes a limiting plate 15 and a limiting groove 16. The limiting plate 15 is fixedly connected to the side of the threaded sleeve plate 4. The limiting groove 16 is opened on the rear side of the inner wall of the dust-proof measurement box 1. The inner wall of the limiting groove 16 and the surface of the limiting plate 15 are slidably connected. Through the setting of the limiting plate 15 and the limiting groove 16, the movement track of the threaded sleeve plate 4 is limited, so that the rotation of the threaded rod 3 can drive the threaded sleeve plate 4 to move.

[0027] Furthermore, the locking component includes a magnetic attraction locking plate 17 and a magnetic attraction locking sleeve 18. The magnetic attraction locking plate 17 is fixedly connected to the top of the weighing and placing frame 5. The magnetic attraction locking sleeve 18 is fixedly connected to the bottom of the threaded sleeve plate 4. The inner wall of the magnetic attraction locking sleeve 18 and the surface of the magnetic attraction locking plate 17 are magnetically clamped and adapted. With the setting of the magnetic attraction locking plate 17 and the magnetic attraction locking sleeve 18, the connection effect of the weighing and placing frame 5 at the bottom of the threaded sleeve plate 4 can be freely and stably carried out.

[0028] Specifically, as Figures 1 - 5 shown, a guide plate 26 is fixedly connected to the bottom of the water storage measurement frame 6.

[0029] Example 2 Please refer toFigures 1 - 5 , the difference between this embodiment and Embodiment 1 is that the main body of the weighing placement frame 5 is a smooth drainage frame 19 with a front door. A lifting plate 20 is placed on the top of the smooth drainage frame 19. A second driving motor 21 is fixedly installed inside the lifting plate 20, and the output end of the second driving motor 21 is fixedly installed with the top of the smooth drainage frame 19. A weighing sensor 22 is fixedly installed at the bottom of the inner wall of the smooth drainage frame 19. The top of the weighing sensor 22 is connected to a drainage mesh frame 23 with a placement platform. A drainage flow groove is provided on the side of the smooth drainage frame 19. A sliding plate 24 is fixedly connected to the top of the smooth drainage frame 19. An annular groove 25 is provided at the bottom of the weighing placement frame 5 near its circumference. The inner wall of the annular groove 25 is slidably connected to the surface of the sliding plate 24. The second driving motor 21 drives the smooth drainage frame 19 to rotate. Under the action of the sliding plate 24 and the annular groove 25, the smooth drainage frame 19 is ensured to rotate smoothly, shake the water liquid infiltrated inside the core material, and then lift the weighing placement frame 5 upward and rotate the smooth drainage frame 19 to rotate, so that the liquid therein is thrown out and flows into the inside of the water storage measurement frame 6 to ensure the liquid level of the water storage measurement frame 6 is restored. The high-efficiency determination of the liquid level volume of the core material can be realized by combining the water storage measurement frame 6 and the weighing placement frame 5.

[0030] Working principle of the utility model: During use, the staff can open the switch door on the dust-proof measurement box 1 to expose the weighing placement frame 5 inside, where core materials can be placed. That is, inside the smooth drainage frame 19 of the weighing placement frame 5, the core materials can be placed on the inner wall of the drainage mesh frame 23 for stable placement. The change in the weight of the heavy object on the weighing sensor 22 can be sensed, and thus the overall weight of the core materials can be sensed. Subsequently, when the driving motor 1 operates, it can drive the threaded rod 3 to rotate. Through the setting of the limiting plate 15 and the limiting groove 16, the movement trajectory of the threaded sleeve plate 4 is limited, so that the rotation of the threaded rod 3 can drive the threaded sleeve plate 4 to move. The movement of the threaded sleeve plate 4 can drive the weighing placement frame 5 to move downward into the water storage measurement box 6, making the weighing placement frame 5 sink into the water in the water storage measurement box 6. To ensure the accuracy of the liquid level volume measurement of the core materials, the liquid level change record of the weighing placement frame 5 without containing the volume can be pre-recorded when it enters the water storage measurement box 6, that is, the liquid level without placing items, the liquid level of the water storage measurement box 6 with the empty weighing placement frame 5 placed, and the liquid level change of the water storage measurement box 6 with the core materials placed in the weighing placement frame, which is generally the liquid level change record of the water storage measurement box 6. The water level in the water storage measurement box 6 will float upward to drive the floating lifting ball rod 8 to adjust its height. The floating lifting ball rod 8 can be limited and guided to move in the limiting sleeve plate 7, and the distance change is sensed under the induction of the induction plate 9 and the distance sensor 10. The distance change record of the two induction plates 9 on the left and right can be recorded when the distance change between the two induction plates 9 is stable and the same. And a waterproof marking lamp 11 is provided at the front side of the bottom of the floating lifting ball rod 8, and a secondary observation record is made under the marking of the transparent measurement scale 12 to avoid the situation that the water cannot fully penetrate during the observation of the core materials getting water inside. The driving motor 21 can be operated to drive the smooth drainage frame 19 to rotate. Under the action of the sliding plate 24 and the annular groove 25, the smooth drainage frame 19 is ensured to rotate smoothly, so as to shake the water liquid infiltrated into the core materials inside. And after the weighing placement frame 5 is lifted upward, the smooth drainage frame 19 is rotated to throw out the liquid inside and flow it into the inside of the water storage measurement box 6 to ensure the liquid level recovery of the water storage measurement box 6. The weighing and volume measurement processes can be combined into one process to achieve the rapid and efficient determination of the core density parameters.
