Description

Technical Field

[0001] The utility model relates to the technical field of cuttings logging processing, in particular to a cuttings logging flushing, screening and collecting device. Background Technique

[0002] Cuttings logging is the first-hand information reflecting the formation lithology. Through cuttings logging, the underground stratigraphic sequence and lithology can be mastered, and the water-bearing situation of the drilled formation can be preliminarily understood. The work of cuttings logging is inseparable from the observation and analysis of cuttings. The freshly taken cuttings are wrapped in mud and cannot be observed. They must be slowly flushed with clean water until the cuttings show their true colors, and then the larger particles are screened out to facilitate the determination of cuttings. Therefore, the effects of cleaning and screening are extremely important.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Referring to Figures 2 - 4 As shown, an embodiment provided by the present invention is a cuttings washing, screening, and collecting device for mud logging, which includes a fixed frame 8 as a connection. One side of the inner wall of the fixed frame 8 is fixedly connected with a second motor 9. A connecting block 13 is arranged at the driving end of the second motor 9 for moving the connecting block 13 back and forth repeatedly. Spray heads 14 are fixedly connected to the bottom ends of the connecting blocks 13. A semi-gear 10 is fixedly connected to the driving end of the second motor 9. The lower side of the outer wall of the semi-gear 10 is meshed with a toothed plate 11. The bottom end of the toothed plate 11 is slidably connected to the lower side of the inner wall of the fixed frame 8. The left and right ends of the toothed plate 11 are respectively fixedly connected to the opposite ends of the connecting block 13. First tension springs 12 are fixedly connected to the front and rear sides of the right end of the toothed plate 11. The other ends of the first tension springs 12 are respectively fixedly connected to the front and rear parts on the right side of the inner wall of the fixed frame 8. The left and right ends of the fixed frame 8 are respectively fixedly connected to the left and right sides of the inner wall of the housing 1.

[0030] Specifically, a controller is arranged at the front end of the housing 1. The controller is electrically connected to a water pump 15, a first motor 3, and a second motor 9. By starting the second motor 9 through the controller, the semi-gear 10 is driven to rotate by the second motor 9. When the semi-gear 10 rotates clockwise, the toothed plate 11 is driven to move leftward, and the connecting blocks 13 and spray heads 14 on both sides of the outer wall are driven to move. When the toothed plate 11 moves to the leftmost side, the semi-gear 10 no longer meshes with the toothed plate 11. Through the elastic force of the first tension spring 12, the toothed plate 11 is pulled to the right. When the toothed plate 11 moves to the rightmost side, after the semi-gear 10 rotates half a circle, it meshes with the toothed plate 11 again and repeats the movement. When the toothed plate 11 is pulled to the right by the first tension spring 12, due to the elastic force of the first tension spring 12, the toothed plate 11 will move repeatedly. After the toothed plate 11 stops moving, it meshes with the semi-gear 10 again, driving the spray heads 14 on both sides to move back and forth to wash the cuttings for mud logging and the screening plate 6, avoiding blockage of some areas of the screen during the washing process, affecting the screening effect and efficiency, and at the same time avoiding uneven spraying, where some areas may be thoroughly cleaned while some areas may be overlooked, improving the cleaning efficiency and screening out larger cuttings.

[0031] Referring to Figure 1 、 Figure 2 and Figure 5As shown, as a temporary collection box 17, a filter screen 18 is fixedly connected to the inner wall of the collection box 17. On the left and right sides of the inner wall of the filter screen 18, there are pull rods 20 respectively, which are used for the installation and disassembly of the collection box 17. On the left and right sides of the inner wall of the collection box 17, clamping grooves 19 are opened. On the inner walls of the clamping grooves 19, there are clamping blocks 22. The shape of the clamping blocks 22 fits the clamping grooves 19. The opposite ends of the clamping blocks 22 are respectively fixedly connected to the opposite ends of the pull rods 20. The rear sides of the clamping blocks 22 are all arc surfaces. On the opposite sides of the outer walls of the pull rods 20, there are second tension springs 21 respectively. The other ends of the second tension springs 21 are respectively fixedly connected to the left and right ends of the outer shell 1.

[0032] Specifically, the water is filtered through the filter screen 18, and other impurities such as scattered sand are collected in the collection box 17. After the filtration, the water flows back to the bottom side of the outer shell 1 and is pumped again through the water pump 15 to wash the logging cuttings. After the cleaning is completed, by pulling the pull rods 20 to both sides, the clamping blocks 22 are taken out of the clamping grooves 19, and then the collection box 17 can be pulled out through the handle to collect and process other impurities such as scattered sand. Before the cleaning and filtration, the collection box 17 is inserted into the outer shell 1. When the arc surfaces of the collection box 17 contact the clamping blocks 22 on both sides, the clamping blocks 22 will slide to both sides. After the collection box 17 is installed in place, the clamping blocks 22 are clamped into the clamping grooves 19 through the second tension springs 21 to complete the installation.

[0033] Refer to Figures 1 - 3 As shown, as the supporting outer shell 1, a first motor 3 is fixedly connected to one end of the outer shell 1. A screening plate 6 is arranged at the driving end of the first motor 3 to vibrate the screening plate 6. A water pump 15 is fixedly connected to one side of the inner wall of the outer shell 1. The water outlet of the water pump 15 is fixedly connected to a corrugated pipe 16. The other end of the corrugated pipe 16 is respectively fixedly connected to the inner wall of the connecting block 13. An eccentric wheel 4 is fixedly connected to the driving end of the first motor 3. The front end of the eccentric wheel 4 is rotatably connected to a rotating rod 5. The other end of the rotating rod 5 is rotatably connected to the inner wall of the screening plate 6. The front and rear ends of the screening plate 6 are respectively rotatably connected to the front and rear sides of the inner wall of the outer shell 1. A collection plate 7 is detachably arranged on the right side of the inner wall of the outer shell 1 to collect the logging cuttings after screening. A feed inlet 2 is fixedly connected to the left side of the inner wall of the outer shell 1. An observation window is opened at the front end of the outer shell 1. A drain valve is fixedly connected to the lower part of the right side of the inner wall of the outer shell 1.

[0034] Specifically, at the water inlet of the water pump 15, there is a detachable filter layer to filter the clear water again. The water pump 15 and the first motor 3 are started through the controller. The water pump 15 pumps out the clear water inside the housing 1 and transports it to the spray head 14 through the corrugated pipe 16 for spraying. The first motor 3 is started to drive the eccentric wheel 4 to rotate. The eccentric wheel 4 drives the rotating rod 5 at the front end to rotate and drives the screening plate 6 to vibrate and screen. The well logging cuttings after screening are discharged into the collection plate 7 on the right side. The staff can remove the collection plate 7 to screen the well logging cuttings. Secondly, the staff can observe the screening process through the observation window. When flushing soft mudstone that is prone to mud making and sandstone that is extremely easy to disperse, stop in due time. At the same time, pay attention to observing whether there is oil and gas display and asphalt blocks during flushing. If so, observe and record in time. When pumping water, the water level will be kept at the bottom end of the collection frame 17. Secondly, after the work is completed, the water is discharged through the drain valve. Before processing, clear water is added into the interior through the groove on the right side.

[0035] Working principle: First, well logging cuttings containing impurities are added into the interior through the feed inlet 2 and fall into the screening plate 6. Then, the water pump 15, the first motor 3 and the second motor 9 are started through the controller. The water pump 15 pumps out the clear water inside the housing 1 and transports it to the spray head 14 through the corrugated pipe 16 for spraying. The first motor 3 is started to drive the eccentric wheel 4 to rotate. The eccentric wheel 4 drives the rotating rod 5 at the front end to rotate and drives the screening plate 6 to vibrate and screen. Then, the second motor 9 drives the half gear 10 to rotate. The half gear 10 rotates clockwise, drives the toothed plate 11 to move to the left, and drives the connecting blocks 13 and the spray head 14 on both sides of the outer wall to move. When the toothed plate 11 moves to the leftmost side, the half gear 10 no longer meshes with the toothed plate 11. Through the elastic force of the first tension spring 12, the toothed plate 11 is pulled to the right. When the toothed plate 11 moves to the rightmost side, after the half gear 10 rotates half a circle, it meshes with the toothed plate 11 again and repeats the movement to spray clear water on the well logging cuttings. The well logging cuttings after cleaning are discharged into the collection plate 7 on the right side through vibration for collection. The water after cleaning contains other impurities such as scattered sand and flows downward. The water is filtered through the filter net 18, and other impurities such as scattered sand are collected in the collection frame 17. The filtered water flows back to the bottom side of the housing 1 and is pumped through the water pump 15 again to wash the well logging cuttings. After the cleaning is completed, by pulling the pull rod 20 to both sides, the clamping block 22 is taken out of the clamping groove 19, and then the collection frame 17 can be pulled out through the handle to collect other impurities such as scattered sand.
