Description

Technical Field

[0001] This invention relates to the field of oil and gas exploration technology, and in particular to a mobile logging sand receiving device. Background Technology

[0002] In oil and gas exploration, the main task of cuttings logging is the observation and analysis of rock cuttings, which is also an important foundation for formation evaluation and oil and gas resource assessment. In cuttings logging, the collection of cuttings samples (i.e., cuttings retrieval) is done by placing a sand-receiving device at a specific location under a vibrating screen. Currently, these devices are fixedly installed below the vibrating screen and cannot be moved in real time. The installation position is determined only based on the initial observed location of the falling cuttings. However, this is not static. After prolonged operation, the screen cloth of the vibrating screen may become clogged or broken. If clogged, the falling location of the cuttings will change, meaning the sand-receiving device cannot be randomly repositioned, thus failing to accurately receive the cuttings and exhibiting poor operational adaptability. Summary of the Invention

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the mobile logging sand receiving device of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0041] like Figure 1 , 2As shown, a mobile logging sand receiving device includes: a housing 1, a casing 2, and a support rod 3. The housing 1 has an upper end face (not shown) with an inlet 4 on the upper end face that allows external materials to enter the housing 1. The casing 2 is fixedly connected to the outer wall of the housing 1, and the axis of the casing 2 extends horizontally. The support rod 3 passes through the casing 2 and can be fixedly connected to an external environmental component. The casing 2 can move along the axial direction of the support rod 3 to adjust the axial position of the housing 1 on the support rod 3. With this technical solution, in practical use, the position of the housing 1 can be moved on the support rod 3 to accurately align the inlet of the housing 1 with the falling position of the material on the vibrating screen. This allows it to adapt to changes in the falling position of rock cuttings on the vibrating screen and accurately receive the material falling from the vibrating screen, greatly improving its operational adaptability.

[0042] In actual production, such as Figure 2 As shown, there are two sleeves 2. The axes of the two sleeves 2 are parallel to each other and are respectively set on both sides of the housing 1. There are two support rods 3, which are respectively inserted into the two sleeves 2. In this way, the two support rods 3 can provide lateral support for the housing 1, thereby ensuring the stability of the housing 1.

[0043] Furthermore, such as Figure 2 , 5 As shown, it includes a positioning mechanism 5, which is connected to the support rod 3 and the sleeve 2 respectively to fix the sleeve 2 on the support rod 3.

[0044] Specifically, such as Figure 4 As shown, the positioning mechanism 5 includes a positioning sleeve 6 and positioning screws 7. The positioning sleeve 6 is sleeved on the support rod 3 and can move relative to the support rod 3 in the axial direction so that the positioning sleeve 6 can abut against the end face of the sleeve 2. A positioning screw hole is provided on the side wall of the positioning sleeve 6, and the positioning screw 7 is threaded into the positioning screw hole and can abut against the outer wall of the support rod 3 to fix the positioning sleeve 6 to the support rod 3. In actual manufacturing, there are two positioning sleeves 6 on each support rod 3, and the two positioning sleeves 6 are located at both ends of the sleeve 2. There are two positioning screws 7, and the two positioning screws 7 correspond to the two positioning sleeves 6 respectively. In use, after the position of the housing 1 is accurately adjusted, the two positioning sleeves 6 can clamp the sleeve 2, and then the two positioning sleeves 6 are fixed to the support rod 3 by the two positioning screws 7 respectively, thereby fixing the position of the housing 1.

[0045] Preferably, such as Figure 1 , 2As shown in Figure 5, the system also includes a support tube 8, and at least one end of the support rod 3 is provided with an adjusting stud 9 that coincides with the axis of the support rod 3. The support tube 8 has an adjusting screw hole 10 whose axis coincides with the axis of the support tube 8 and matches the adjusting stud 9, so that the support tube 8 is threadedly connected to the support rod 3, and the support rod 3 is connected to the external environmental component through the support tube 8. In this way, by adjusting the length of the adjusting stud 9 screwed into the adjusting screw hole 10, the support rod 3 can be extended through the support tube 8, thereby allowing the support rod 3 to be connected to the external environmental component in different working environments. It should be noted that in actual manufacturing, as shown in the figure, each support rod 3 can be connected to both ends of the support tube 8 to improve work adaptability.

[0046] As one possible implementation method, such as Figure 1 As shown, the housing also includes a water spray pipe 11 and a discharge pipe 12. The housing 1 has an upper cavity 13 and a lower cavity 14. The upper cavity 13 has an inlet 4 formed on its upper end face. A through hole is provided on the side wall of the upper cavity 13. One end of the water spray pipe 11 is connected to an external water source, and the other end passes through the through hole and extends into the upper cavity 13. The lower cavity 14 is located below the upper cavity 13 and communicates with it. The lower cavity 14 has a bottom wall facing the upper cavity 13, and a discharge port (not shown in the figure) is provided on the bottom wall. The discharge pipe 12 is located outside the housing and is connected to the discharge port. In this way, the material enters the upper cavity 13 from the inlet 4, falls into the lower cavity 14, and is finally discharged outside the housing 1 through the discharge pipe 12. The water spray pipe 11 sprays water into the upper cavity 13 and falls into the lower cavity 14, driving the material to be discharged from the discharge pipe 12. The lower cavity 14 is shaped like a frustum tapering from top to bottom to facilitate the movement of materials and water toward the discharge port, where they are then discharged from the discharge pipe 12.

[0047] As one possible implementation, a screening device (not shown in the figure) is also included. The screening device is installed at the feed inlet 4 to screen the material entering the housing 1 from the feed inlet 4, so that the mobile logging sand receiving device can selectively receive the material shaken off by the vibrating screen.

[0048] Specifically, such as Figure 1 , 3As shown, the screening device includes a first support beam 15, a second support beam 16, and screen columns 17. The feed inlet 4 is rectangular in shape. The first support beam 15 and the second support beam 16 are fixedly connected to two parallel edges of the feed inlet 4. A first groove 18 is provided on the first support beam 15, and a second groove 19 is provided on the second support beam 16. The two ends of the screen column 17 are located within the first groove 18 and the second groove 19, respectively. There are at least two screen columns 17. The number of first grooves 18 is equal to the number of screen columns 17 and corresponds one-to-one. At least two first grooves 18 are evenly distributed along the extension direction of the first support beam 15. The number of second grooves 19 is equal to the number of first grooves 18 and corresponds one-to-one. In actual use, the distance between adjacent screen columns can be changed by adjusting the number of screen columns 17 to adapt to the screening requirements of the material.

[0049] Furthermore, such as Figure 3 As shown, it also includes an adjusting cover plate 20, which is movably connected to the upper surface and can cover the feed inlet 4 to adjust the opening amount of the feed inlet 4. Specifically, as shown in the figure, a handle 21 can be provided on the adjusting cover plate 20 so that the operator can adjust its position using the handle 21. The first support beam 15 is provided with a first limiting groove 22 extending in the same direction as the first support beam 15, and the second support beam 16 is provided with a second limiting groove 23 extending in the same direction as the second support beam 16. On a cross-section perpendicular to the extension direction of the first support beam 15, the opening of the first limiting groove 22 is opposite to the opening of the second limiting groove 23, and both ends of the adjusting cover plate 20 are located within the first limiting groove 22 and the second limiting groove 23, respectively. This ensures that the adjusting cover plate 20 moves along the extension directions of the first support beam 15 and the second support beam 16, while also preventing the adjusting cover plate 20 from falling off the top of the housing 1.

[0050] As one possible implementation method, such as Figure 1 As shown, it also includes an adjusting leg 24, which includes an upper support 25, a lower support 26, and a connecting sleeve 27. The adjusting sleeve has a connecting screw hole 30. The upper support 25 is vertically arranged, with its upper end fixedly connected to the housing 1 and its lower end being a first connecting end 28. The first connecting end 28 has an external thread that matches the connecting screw hole 30, so that the first connecting end 28 is threaded into the connecting screw hole 30 from the top of the connecting sleeve 27. The lower support 26 is vertically arranged, with its upper end being a second connecting end 29. The second connecting end 29 has an external thread that matches the connecting screw hole 30, so that the second connecting end 29 is threaded into the connecting screw hole 30 from the bottom of the connecting sleeve 27. The overall length of the adjusting leg 24 can be adjusted by changing the length by which the first connecting end 28 and / or the second connecting end 29 are screwed into the connecting screw hole 30. Figure 5As shown, the number of adjusting legs 24 is at least three, and the projections of the axes of the at least three adjusting legs 24 onto the horizontal plane are not on the same straight line. In actual operation, the levelness of the housing 1 (i.e., the levelness of the upper end face) can be adjusted by adjusting the overall length of the at least three adjusting legs 24.

[0051] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
