Description

Technical Field

[0001] The utility model relates to the technical field of mud storage tanks, in particular to a mud storage tank convenient for loading and unloading. Background Technique

[0002] A mud storage tank, also known as a mud tank or a drilling fluid tank, is one of the commonly used equipment in oil drilling. It is mainly used for storing and stirring drilling fluid. A mud storage tank is a device for storing and transporting drilling fluid. It can transport clean drilling fluid to the wellhead during the drilling process, playing roles such as cooling the drill bit, reducing the friction of the drill bit, and cleaning the debris at the bottom of the well, so as to ensure the normal operation of the drill bit. At the same time, the drilling fluid can also maintain the stability of the wellbore, control the formation pressure, and play a protective role for the formation; generally, it is cylindrical or square, and most of its materials are made of steel plates welded together, and a special anti-corrosion coating is applied inside to prevent corrosion. The size and shape of the tank body are determined according to specific usage requirements. The discharge port is usually located at the bottom of the tank body, and the mud is discharged through a pipeline to the next processing unit, while the feed port is located at the top of the tank body for injecting fresh mud; the mud storage tank has the following remarkable characteristics: high volume and pressure tolerance, adjusting the density of drilling fluid, maintaining the stability of the wellbore wall, and reducing the frictional resistance; in oil and gas drilling operations, the application of mud storage tanks is very extensive. It is not only one of the indispensable equipment in the drilling process, but also plays a crucial role in the safe and efficient conduct of the entire drilling operation;

[0003] Referring to the Chinese patent authorization announcement number CN211230314, the authorization announcement date is August 11, 2020, which discloses a large-capacity stackable mud storage tank. For this large-capacity stackable mud storage tank, the mud is stored by pouring it into the interior of the storage tank body through the feed pipe. Since the bottom of the storage tank body is a hemispherical body, when the mud is discharged, it can effectively prevent the mud in the dead corner from not being discharged. When discharging the mud through the discharge pipe, some mud may stick to the tank wall. Through the rotation of the rotating motor, the rotating rod is driven to rotate, so that the scraper rotates on the inner wall of the storage tank body, scraping off the mud sticking to the wall, achieving the purpose of uniform discharge;

Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Specific embodiment 1

[0032] This embodiment is a mud storage tank that is convenient for loading and unloading.

[0033] As Figures 1-5 shown, a pulley 2 is fixedly connected to the lower side of the bottom plate 1, and the pulleys 2 are arranged in an array. A support frame 3 is provided on the upper side of the bottom plate 1. The support frames 3 are symmetric about the vertical central axis of the mud storage tank body 6. The inner side of the support frame 3 on the left side above the bottom plate 1 is rotatably connected to a first connecting ring 4, and the inner side of the support frame 3 on the right side above the bottom plate 1 is fixedly connected to a second connecting ring 5. The inner side of the first connecting ring 4 is fixedly connected to the mud storage tank body 6, and the inner side of the second connecting ring 5 is in close contact with the lower side of the mud storage tank body 6. A slot 7 is provided on the upper side inside the mud storage tank body 6. The slot 7 is symmetric about the vertical central axis of the mud storage tank body 6 in the front and back directions. The slot 7 is engaged with a cleaning piece 8, and the cleaning piece 8 is threadedly connected to a screw rod 9. The right side of the screw rod 9 is fixedly connected to the output shaft of the motor 10, and the left side of the screw rod 9 is rotatably connected to the inner side of the mud storage tank body 6 through a bearing. The motor 10 is fixedly installed on the right side of the mud storage tank body 6. A feeding port 11 is provided above the front side of the mud storage tank body 6, and the feeding port 11 is engaged with a lid 12. A discharging port 13 is provided on the lower side of the mud storage tank body 6.

[0034] A support base 14 is provided on the right side of the mud storage tank body 6. A connecting rod 15 is fixedly connected to the upper side of the support base 14. The upper side of the connecting rod 15 is fixedly connected to the side surface of the mud storage tank body 6. The lower side of the support base 14 is slidably connected to a moving block 16. The moving block 16 is rotatably connected to the upper end of a cylinder 17. The cylinder 17 is arranged on the upper side of the bottom plate 1.

[0035] It should be noted that after the bottom plate 1 is moved by the pulley 2, only an obstacle needs to be placed on the side of the pulley 2 to prevent the pulley 2 from moving. Even when the cylinder 17 is lifted for discharging, it will not slide, which is convenient for operation. Specific Embodiment Two

[0036] This embodiment is an embodiment of a cleaning mechanism for a mud storage tank that is convenient for loading and unloading.

[0037] Before adding mud, start the motor 10. Since the lead screw 9 is threadedly connected to the cleaning blade 8, and the upper side of the cleaning blade 8 is affected by the slot 7, no other position of the cleaning blade 8 will have a force acting on the inside of the mud storage tank body 6. This can prevent the cleaning blade 8 from wearing the inner wall of the mud storage tank body 6. Move the cleaning blade 8 to the right side inside the mud storage tank body 6 to maximize the use of the space inside the mud storage tank body 6. Then open the lid 12 on the feeding port 11, and mud can be added to the inside of the mud storage tank body 6. When it is necessary to discharge the mud in the mud storage tank body 6, just turn the valve in front of the discharge port 13, and the mud in the mud storage tank body 6 can be discharged from the discharge port 13. After discharging, start the motor 10, and the cleaning blade 8 can be moved to the left, so that the mud sticking to the inner wall of the mud storage tank body 6 can be cleaned, preventing mud residue on the inner wall of the mud storage tank body 6 and avoiding corrosion. Specific Embodiment Three

[0038] This embodiment is an embodiment of a lifting mechanism for a mud storage tank that is convenient for loading and unloading.

[0039] During the discharging process, it is necessary to start the cylinder 17 to make the right side of the mud storage tank body 6 higher than the left side of the mud storage tank body 6, so as to facilitate discharging. Since the left side of the mud storage tank body 6 is rotatably connected to the support frame 3 through the first connecting ring 4, and the lower right side of the mud storage tank body 6 is in close contact with the upper side of the second connecting ring 5, the mud storage tank body 6 can rotate around the connecting shaft of the first connecting ring 4 and the support frame 3 on the upper side of the pulley 2. During the operation of the cylinder 17, the moving block 16 will push the support base 14 upward, and the moving block 16 will also rotate. In addition, the connecting rod 15 on the upper side of the support base 14 can increase the force-bearing area between the support base 14 and the moving block 16, prevent the right side of the mud storage tank body 6 from being damaged due to excessive force, and extend the service life.
