Description
Известны буровые долота, шарошки которого имеют фрезерованные клиновые зубь . Эти долота предназначены дл буренп однородных пород средней твердости. Недостатком таких долот вл етс то, что нри бурении твердых пропластков происходит быстрое затупление зубьев и увеличиваетс площадь соприкосновени зуба с забоем, уменьшаетс удельное давление иа забой, в результате чего происходит резкое снижение механической скорости бурени .Known drill bits, cones which have milled wedge teeth. These chisels are intended for medium-hard homogenous rocks. The disadvantage of such bits is that when drilling solid layers, teeth become blunt quickly and the area of tooth contact with the face increases, the specific pressure decreases and the bottomhole pressure results in a sharp decrease in the mechanical drilling rate.
В предлагаемой шарошке, в ее теле между зубь ми выполнены углублени , что повышает скорость бурени .In the proposed cone, in its body, recesses are made between the teeth, which increases the speed of drilling.
На фиг. 1 изображено долото, общий вид; на фиг. 2 - зубь шарошки и сечени I, Н,FIG. 1 shows a chisel, a general view; in fig. 2 - the tooth of the roller cutter and section I, H,
П1 и IV. Долото состоит из лап 1, сваренных между собой н шарошек 2. В теле шарошки между зубь ми нмеютс цилиндрические углублени .P1 and IV. The chisel consists of paws 1, welded between themselves n cones 2. In the body of cone between the teeth there are cylindrical recesses.
По мере изиоса зуба но высоте плошадь контакта зуба с забоем остаетс почти посто нной . Кроме того, прочность такого зуба выше, чем у долот с клиновыми зубь ми.As the tooth progresses at the height, the area of tooth contact with the face remains almost constant. In addition, the strength of such a tooth is higher than that of chisels with wedge teeth.
Предмет изобретени Subject invention
Шарошка бурового долота с фрезерованными зубь ми, отличающа с тем, что, с целью новынгени скорости бурени , в теле шарошки между зубь ми выполнены углублени .The bit of a drill bit with milled teeth, characterized in that, in order to increase the drilling speed, there are recesses in the body of the cutter between the teeth.
