Description

Diamond rigid body drill bit

Technical Field

Background

The drill bit with cutting edges is called a diamond drill bit. The drill bit belongs to an integrated drill bit, has no movable parts, is relatively simple in structure, has high strength, high wear resistance and impact resistance, and is one of three new technologies for drilling in the world in the 80 th 20 th century.

At present, diamond-impregnated bits are used more and more in life, wherein compared with surface-impregnated bits, diamond-impregnated bits have the advantages of low requirements on diamond grade, good impact load resistance and simpler manufacture, and when the diamonds impregnated with bit lip surfaces are sheared, the influence on drilling effect and the sensitivity to violation of operation rules are less than those of the surface-impregnated bits.

The diamond-impregnated bit uses a plurality of small diamonds on the lip surface to scratch and grind the rock at the bottom of the hole for breaking the rock, and has the characteristics of high drilling speed, high core taking rate, low drilling cost and the like. Because the working condition of the drill bit in the drilling process is very complex, the factors of the diamond grade, the matrix performance (ensuring the self-sharpening of the drill bit), the shape and the area of the lip surface, the inner and outer diameter protection, the waterway design and the like in the drill bit are very important for the overall performance of the drill bit. Wherein, the waterway structure of drill bit, including mouth of a river, basin, in the aspect of in time getting rid of the hole bottom detritus and cooling drill bit play the important role, directly influence the hole bottom and wash and creep into the effect.

When the structure, especially the structure design of a water gap, of the existing diamond-impregnated bit is carried out, the main consideration is that: the drilling fluid can be smooth, the rock debris generated during drilling can be taken away, the drill bit can be cooled, and the improvement of the water gap structure on the drilling efficiency is not focused enough. Therefore, we improve this and propose a diamond rigid body drill bit.
