Drill bit alloy with good heat-conducting performance

Abstract

The invention discloses a drill bit alloy with good heat-conducting performance. The drill bit alloy includes the following compositions in parts by weight: 80-100 parts of diamond micro-powder, 50-60parts of tungsten carbide powder, 1000-1200 parts of iron, 100-150 parts of Gr, 80-120 parts of V, 10-30 parts of S, 100-120 parts of Cu, 40-50 parts of Ni, 40-50 parts of Cr3C2, and 40-50 parts of MnC. According to the drill bit alloy with the good heat-conducting performance, a provided alloy drill bit is prepared from the following compositions in parts by weight: 80-100 parts of the diamond micro-powder, 50-60 parts of the tungsten carbide powder, 1000-1200 parts of the iron, 100-150 parts of the Gr, 80-120 parts of the V, 10-30 parts of the S, 100-120 parts of the Cu, 40-50 parts of theNi, 40-50 parts of the Cr3C2, and 40-50 parts of the MnC, the drill bit can have good hardness and wear resistance, meanwhile, the heat-conducting performance of the drill bit is enhanced, and safe drilling exploration is ensured.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a drill bit alloy with good thermal conductivity. Background technique [0002] The roller cone bit is the most widely used type of drilling bit. When the roller cone bit is working, the cutting teeth alternately contact the bottom of the well, the rock-breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to penetrate into the formation; the total length of the working blade is large, so the wear is relatively reduced. Roller cone bits can adapt to a variety of formations from soft to hard. The roller cone bit has been widely used as a tool for drilling rock formations, and the significant improvement in the performance of the bit will directly reduce the cost of drilling, especially in the past decade. Service life and rate of penetration are two performance metrics that ultimately dete...
