Description

[0002] When the hydraulic composite sand cleaner is in the well, the spiral strips of the upper and lower joints cut the cuttings bed on the lower well wall, and the drilling fluid returned from the annulus enters the right-handed spiral groove of the lower joint, passes through the straight groove of the vortex generator, changes direction, enters the left-handed spiral groove of the upper joint and returns upward. At the same time, the vortex generator rotates under the drive of the drilling fluid to form a strong vortex field, which can prevent the cuttings from sinking.
