Oil drilling and geological drilling in the most used cone bit.

       Oil drilling and geological drilling in the most used cone bit. The
cone bit has the effect of rocking, crushing and shearing the formation
rock in rotation, so the cone bit can accommodate soft, medium and hard
layers. The number of roller bits can be divided into single cone, double cone, three cone and multi-cone bit. At present, the most widely used at home and abroad, the most common is the three cone bit.

There
are three nozzles on the inside of the cone of the three cone bits. The
holes in the three nozzles are the parts of the drilling fluid. The
drilling fluid passes through the bore of the nozzle, the circulating
drilling fluid, the cooling bit, the drilling tool, ,
And play a large hole in the bottom of the rock gap, the role of
auxiliary rock breaking, often said that the high pressure jet drilling,
refers to the use of small nozzle water, high pump pressure, nozzle in
the bottom of the ultra-high pressure water jet, Rock, to improve the drilling speed. So the oil drill nozzle in the drilling plays a very big role, in
order to improve the wear resistance of the nozzle, the nozzle is
generally made of cemented carbide, made by powder metallurgy, shape for
a cylindrical.
