Technical Field

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

[0002] 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 loose, cracked, easy to collapse and fall off, and unstable rock formations such as swelling and peeling when exposed to water.

[0003] In the prior art, a Chinese patent with publication number CN217312880U discloses a drilling fluid stirring device. By using a lifting drive mixing and stirring structure and a mechanical drive method, the mixing and stirring of the drilling fluid is fully automatic, which reduces the use of manpower and can accurately control the amount of added materials to ensure the quality of the drilling fluid. This solves the problem that the existing drilling fluid is mostly manually added and the drilling fluid is stirred and mixed by a simple handheld stirring drive device, which is prone to uneven stirring and inaccurate filling, resulting in poor overall quality of the drilling fluid and affecting the use of drilling.

[0004] However, the above device cannot be moved when in use, is inconvenient to carry, cannot view the state of drilling fluid in real time, and has residual material at the end of the device discharge. Utility Model Content

[0007] Furthermore, the lifting device includes a lifting hydraulic rod and a fixing plate, wherein the lifting hydraulic rod is fixed to an upper end of the bottom plate, and the fixing plate is fixed to a telescopic shaft of the lifting hydraulic rod.

[0008] Furthermore, the stirring device includes a motor, a stirring shaft and a stirring paddle, the motor is fixed on the upper side of the fixed plate and the output shaft passes through the fixed plate and the charging cover, the stirring shaft is fixed at the output end of the motor, and the stirring paddle is fixed on the stirring shaft.

[0009] Furthermore, the observation structure includes a transparent annular plate and a scraper, wherein the transparent annular plate is fixed on the upper side of the charging barrel, and the scraper is fixed on the stirring shaft.

[0010] Furthermore, the lifting and discharging structure includes an opening and a lifting hydraulic rod. The opening is opened at one end of the base plate and is arranged through it. The lifting hydraulic rod is fixed to the upper end of the base plate and is arranged through the opening when the telescopic shaft is extended and retracted. The opening and the lifting hydraulic rod are symmetrically arranged in two groups.

[0011] Furthermore, when the lifting hydraulic rod is not extended or retracted, the loading cover is sleeved on the outside of the transparent circular plate.

[0012] Furthermore, when the lifting hydraulic rod is not extended or retracted, the scraper and the transparent annular plate are in corresponding positions.

[0023] like Figure 1-3 As shown, the utility model proposes a downhole drilling fluid stirring device for drilling, comprising a base plate 1, a charging barrel 2, a lifting device 3, a charging cover 4, a stirring device 5, an observation structure 6 and a lifting and discharging structure 7. The charging barrel 2 is fixed at the center of the upper side of the base plate 1, the lifting device 3 is arranged at one end of the upper side of the base plate 1, the charging cover 4 is fixed on the lifting device 3, the stirring device 5 is arranged on the lifting device 3, the observation structure 6 is arranged on the charging barrel 2 and the stirring device 5, the lifting and discharging structure 7 is arranged at one end of the upper side of the base plate 1, and a discharging port 19 is provided at the lower part of one side of the charging barrel 2. In order to facilitate the movement of the device, four sets of wheels 8 are provided on the lower side of the base plate 1, and a push plate 9 is provided at one end of the base plate 1.

[0024] As the instruction manual Figure 1 As shown, in order to facilitate the lifting of the loading cover 4 for loading, the lifting device 3 includes a lifting hydraulic rod 10 and a fixing plate 11. The lifting hydraulic rod 10 is fixed to one end of the upper side of the bottom plate 1, and the fixing plate 11 is fixed to the telescopic shaft of the lifting hydraulic rod 10.

[0025] As the instruction manual Figure 3 As shown, in order to make the drilling fluid mixed more evenly, the stirring device 5 includes a motor 12, a stirring shaft 13 and a stirring paddle 14. The motor 12 is fixed on the upper side of the fixed plate 11 and the output shaft passes through the fixed plate 11 and the loading cover 4. The stirring shaft 13 is fixed at the output end of the motor 12, and the stirring paddle 14 is fixed on the stirring shaft 13.

[0026] As the instruction manual Figure 1 , 3As shown, in order to facilitate observation of the stirred drilling fluid, the observation structure 6 includes a transparent annular plate 15 and a scraper 16. The transparent annular plate 15 is fixed on the upper side of the charging barrel 2, and the scraper 16 is fixed on the stirring shaft 13. In order to prevent the drilling fluid from affecting the line of sight during stirring, when the lifting hydraulic rod 10 is not extended or retracted, the scraper 16 and the transparent annular plate 15 are positioned correspondingly. In order to keep the device tidy when not in use, when the lifting hydraulic rod 10 is not extended or retracted, the charging cover 4 is sleeved on the outside of the transparent annular plate 15.

[0027] As the instruction manual Figure 1-2 As shown, in order to ensure that there is no residue when discharging materials, the lifting and discharging structure 7 includes an opening 17 and a lifting hydraulic rod 18. The opening 17 is opened at one end of the base plate 1 and is arranged to pass through. The lifting hydraulic rod 18 is fixed to one end of the upper side of the base plate 1 and passes through the opening 17 when the telescopic shaft is extended and retracted. The opening 17 and the lifting hydraulic rod 18 are symmetrically arranged in two groups.

[0028] During specific use, the push plate 9 is pushed to move the device to a position close to the drilling machine, the lifting hydraulic rod 10 is operated to raise the charging cover 4 and the stirring device 5, and the raw materials of the drilling fluid are put into the charging barrel 2 in sequence, and the lifting hydraulic rod 10 is operated again to lower the charging cover 4 and the stirring device 5, and the motor 12 is operated to make the stirring shaft 13 drive the stirring paddle 14 to start stirring. At this time, the stirring situation can be observed through the transparent circular plate 15. In order to prevent the drilling fluid from splashing onto the transparent circular plate 15 and affecting the line of sight during stirring, the scraper 16 on the upper part of the stirring shaft 13 scrapes the drilling fluid splashed onto the transparent circular plate 15 when the stirring shaft 13 is stirring, and the material is discharged after being evenly stirred. At the end, due to the decrease in material pressure, the material is not only slowly discharged but also not easy to be discharged cleanly. At this time, the lifting hydraulic rod 18 is operated to make its telescopic shaft pass through the opening 17 and rest on the ground to raise one side of the bottom plate 1, so that the tilt of the charging barrel 2 releases the residual drilling fluid faster and more completely. The above is the use process of the entire downhole drilling fluid stirring device for drilling.
