Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mud cleaning in a mud tank, and in particular to a mud tank that is easy to clean. Background Art
[0002] Mud tanks are crucial equipment in the oil drilling process, primarily used to store and process the mud produced during drilling. Their working principle is to carry the slurry from the wellhead to the mud pump, separating particles within the system and weighting these particles. Through a mixed and matched approach, the entire circulation system can be regulated and controlled. The degassing equipment on the mud tank effectively removes harmful gases from the mud circulation system, providing a positive working environment for personnel. Therefore, mud tanks are essential equipment in oil drilling, playing a key role in ensuring the smooth progress of the drilling process and protecting the environment.
[0003] The current mud tank structure is as shown in the attached instructions. Figure 1-2 As shown, it is usually a rectangular parallelepiped structure with an inner cavity, which can store a large amount of mud for mud circulation during drilling operations. After the drilling operation is completed, the mud usually loses its effectiveness and needs to be cleaned. After the mud is pumped out from the mud tank by the mud pump, the residual mud accumulated on the inner wall and bottom of the mud tank needs to be cleaned with clean water. Since the mud is sticky, it is usually cleaned after cleaning. Figure 3-4 As shown, there is still mud remaining on the inner wall and bottom of the mud tank. After increasing the flushing pressure, the mud on the side wall and bottom can be further cleaned. However, for the mud remaining at the bottom corners of the inner cavity of the mud tank, since the mud is adhered to the side wall and the bottom, it is difficult to completely clean the residual mud in this area. When the mud tank is used again to store mud for drilling operations, the residual mud will be mixed with new mud, and the previously uncleaned mud is usually agglomerated. When it is mixed with new mud and used in drilling circulation, it usually causes blockage of the mud extraction pump and the mud channel in the well, affecting the normal progress of the drilling operation. At the same time, it is also easy to cause blockage and damage to the equipment, increasing operating costs. Summary of the Invention
[0004] In response to the above-mentioned problems, the present application aims to provide a mud tank that is easy to clean, which can replace the problem of mud easily accumulating on the corners of the inner bottom surface of the current rectangular mud tank, so that the mud will not stick to and stay on the inner bottom surface of the mud tank during cleaning, thereby facilitating the thorough cleaning of the residual mud in the mud tank and solving the impact on subsequent drilling operations.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a mud tank that is easy to clean, the mud tank having an inner cavity for storing mud, characterized in that a cleaning structure without retained mud is provided on the bottom side of the inner cavity of the mud tank, and a mud cleaning guide structure is provided on the bottom surface of the inner cavity of the mud tank.
[0006] Preferably, the cleaning structure is a circular arc structure in which the bottom side of the inner cavity of the mud tank is arranged to be connected to the side wall of the mud tank.
[0007] Preferably, the mud cleaning guide structure is a structure in which the bottom surface of the mud tank is arranged to be inclined toward one side in its length direction.
[0008] Preferably, a guide groove is provided on the inner bottom surface of the mud tank, and the guide groove has a side wall surface for blocking the mud.
[0009] The beneficial effect of the present application is that the bottom side of the inner cavity of the mud tank is set to a cleaning structure without retained mud. This structure can replace the problem of mud easily accumulating at the corners of the inner bottom surface of the current rectangular mud tank, so that the mud will not stick to and stay on the inner bottom surface of the mud tank during cleaning, thereby facilitating the thorough cleaning of the residual mud in the mud tank and solving the impact on subsequent drilling operations.
[0010] The mud cleaning guide structure can guide the mixture of mud and cleaning water during the mud cleaning process, avoiding the problem of mud adhering to and remaining in the mud tank again during the discharge process, thereby further improving the thoroughness of mud cleaning in the mud tank and reducing the impact on subsequent operations.

[0021] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Refer to the attached Figures 1 to 9 The mud tank shown is an easy-to-clean mud tank, and the mud tank 1 has an inner cavity 1a for storing mud. When the drilling operation is completed and the mud in the mud tank is extracted and cleaned, in order to solve the current problem that mud is prone to remain at the corners of the bottom of the inner cavity and is difficult to clean, the present application provides a cleaning structure without mud retention on the bottom side of the inner cavity 1a of the mud tank 1. The cleaning structure replaces the problem of mud easily remaining at the corners of the inner bottom of the current rectangular mud tank, so that the mud will not stick to and stay on the inner bottom of the mud tank during cleaning, thereby facilitating the thorough cleaning of the residual mud in the mud tank and solving the impact on subsequent drilling operations.
[0023] In order to further completely clean the residual mud in the mud tank to the outside of the mud tank, a mud cleaning guide structure is provided on the bottom surface of the inner cavity 1a of the mud tank 1, which can guide the mixture of mud and cleaning water during the mud cleaning process, and avoid the mud from contacting the side wall of the mud tank again during the discharge process, which causes the mud to adhere to the residual problem again, thereby further improving the thoroughness of the mud cleaning in the mud tank and reducing the impact on subsequent operations.
[0024] Specifically, such as Figure 5 As shown, the cleaning structure is to set the bottom side of the inner cavity 1a of the mud tank 1 to an arc structure connected to the side wall of the mud tank 1. Compared with the current rectangular parallelepiped structure, the arc structure does not have the corner structure of the inner cavity bottom surface of the rectangular parallelepiped tank body, and thus does not cause the mud to be fastened and adhered and stay. In the subsequent cleaning process of the tank body, the small amount of mud remaining on the bottom surface can be effectively rinsed and cleaned quickly ( Figure 5 The arrow d in the middle shows the flow direction of the mud after cleaning), which solves the problem of incomplete mud cleaning in the mud tank.
[0025] After the above-mentioned mud flushing and cleaning, the mud mixed cleaning liquid will gather at the arc center of the bottom surface of the inner cavity ( Figure 5 As shown), in order to facilitate the cleaning of the accumulated mud mixture, it is led out to the outer wall of the mud tank, as shown in FIG. Figure 6 As shown, the mud cleaning guide structure is a structure in which the bottom surface of the mud tank 1 is set to be inclined toward one side in its longitudinal direction. This inclined structure can facilitate the accumulated mud liquid to flow out toward the lower side, solve the problem of mud liquid remaining on the bottom surface of the inner cavity, and realize the mud liquid self-flowing and cleaning effect.
[0026] During the mud flushing process inside the mud tank, the flushing water usually has a certain flushing water pressure. Figure 7 The direction of the vertical flushing (as indicated by the arrow e) will drive the mud liquid to flow in the inner cavity in an undirected manner. Figure 7 As shown by the middle arc arrow f), the mud liquid that accumulates on the center of the inner cavity bottom surface and flows out obliquely will flow back to the side wall of the mud tank again, which will cause the mud to remain on the side wall again, resulting in the problem of incomplete mud cleaning. Therefore, in order to solve this problem, Figure 8-9 As shown, the inner bottom surface of the mud tank 1 is provided with a guide groove 1b (preferably, an opening is provided at the bottom of the mud tank 1, and a sealing plate 2 is provided at the bottom of the opening, and the sealing plate is an oblique structure), and the guide groove 1b has a side wall surface c that blocks the mud. During the mud flushing and cleaning operation, the mud on the side wall is driven by the flushing water and accumulates in the guide groove 1a, and flows outward along the inclined structure of the bottom surface (the mud tank side wall is provided with an outlet, not shown in the figure). Under the driving action of the cleaning water, the mud cleaning liquid accumulated in the guide groove 1a will have a certain blocking effect through the side wall surface c of the guide groove 1a, limiting the backflow of the mud liquid accumulated in the guide groove 1a on the side wall, thereby avoiding the mud from remaining on the inner cavity side wall again during the cleaning process, and further improving the thoroughness of the mud cleaning. The bottom surface and side wall surface c of the preferred guide groove 1b are both arc and arc transition surface structures to avoid the residue of mud in the guide groove 1a.
[0027] The principle of this application is as follows: when cleaning the mud in the mud tank, the mud is first extracted by a mud pump. After the extraction is completed, a high-pressure water gun is used to clean the mud remaining on the inner side walls and bottom surface of the mud tank. During the cleaning process, the mud remaining on the side walls will accumulate in the guide groove 1a on the bottom surface and will be discharged automatically due to the inclined structure of the bottom surface of the mud tank. Under the driving action of the cleaning water, the mud cleaning liquid accumulated in the guide groove 1a will have a certain blocking effect through the side wall surface c of the guide groove 1a, limiting the backflow of the mud liquid accumulated in the guide groove 1a on the side wall, thereby preventing the mud from remaining on the inner side wall again during the cleaning process, and achieving a thorough cleaning operation of the residual mud.
[0028] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
