Description

Technical Field

[0001] The utility model belongs to the technical field of drilling fluid configuration, and in particular relates to a drilling fluid stirring device for drilling. Background Art

[0002] At present, drilling projects cannot do without the use of drilling fluid. Drilling fluid is the circulating flushing medium used in the hole during the drilling process. Drilling fluid is the blood of drilling, also known as drilling flushing fluid. Drilling fluid can be divided into clean water, mud, clay-free flushing fluid, emulsion, foam and compressed air according to its composition. Clean water is the earliest drilling fluid used. It does not need to be treated and is easy to use. It is suitable for intact rock formations and areas with sufficient water sources. Mud is a widely used drilling fluid, mainly suitable for unstable rock formations such as loose, cracked, prone to collapse and block falling, and swelling and peeling when exposed to water. Drilling equipment is not protected by drilling fluid and is very easy to be damaged, which increases the drilling cost. Replacing equipment after damage prolongs the construction period of the project.

[0003] The drilling fluid under the existing technology often requires the preparation of multiple raw materials, and after the preparation is completed, some drilling fluid cannot be completely discharged. After remaining in the tank for a long time, it will form lumps and block the discharge pipe. In addition, the drilling fluid stirring device under the existing technology is not convenient for cleaning the inside of the tank after use. After the drilling fluid is discharged, residual drilling fluid will adhere to the tank wall and the stirring blades and spiral stirring rods and solidify, which will affect the subsequent stirring quality of the drilling fluid after solidification.
