Abstract

The invention discloses treatment equipment for a PDC drill bit out of a well. The treatment equipment comprises a box body and a treatment barrel, a rotary table is arranged on the upper surface of the box body, the rotary table is driven by a driving assembly to rotate, the rotary table comprises a square step surface, and the step surface is used for bearing a drill bit loading and unloading device; the treatment barrel is positioned below the rotary table, the treatment barrel and the rotary barrel are in motive seal fit, the treatment barrel and the box body are fixed, and a discharge valve is arranged at the bottom of the treatment barrel; and the treatment barrel is used for accommodating a treatment agent. According to the treatment equipment for the PDC drill bit out of the well, the problem that in the prior art, a large amount of manpower is consumed in stripping of balling rock debris wrapping the drill bit is solved, and the purposes of reducing the stripping difficulty of the balling rock debris of the PDC drill bit and reducing manpower consumption are achieved.

Description

technical field [0001] The invention relates to the field of oil drilling, in particular to processing equipment for drilling PDC drill bits. Background technique [0002] PDC drill bit, that is, polycrystalline diamond compact drill bit, is formed by using polycrystalline diamond as a small cutting block and inserting or sintering it on the drill body. In the field of petroleum drilling, PDC bits are suitable for drilling in soft to medium-hard formations, and such formations are prone to induce bit balling, so in the process of a large number of on-site construction, there are mud balls after the PDC bit comes out of the well. The probability is much greater than that of roller cone bits. For the PDC bit with mud bag phenomenon, it is necessary for on-site drillers to peel off the mud bag cuttings coated on the drill bit. It is very labor-intensive, and there is no good solution for this in the prior art. And after the PDC bit is removed from the well, if it is placed w...
