Abstract

The invention discloses an alloy drill bit material for petroleum drilling and production and a preparation method thereof, and relates to the technical field of alloy material preparation. The alloydrill bit material contains the following chemical components of, by mass, 0.5%-0.8% of carbon, 3.5%-4.2% of lithium, 2.5%-3.0% of molybdenum, 3.0%-4.5% of tungsten, 1.2%-2.7%% of aluminum, 1.1%-1.4%of chromium, 1.2%-2.6% of copper, 0.3%-0.6% of silicon, 2.5%-2.9% of cobalt, 2.3%-6.5% of nickel, 0.003%-0.006% of vanadium, 0.003%-0.005% of titanium, 1.4%-2.4% of niobium, 0.02%-0.05% of boron, 0.01%-0.04% of sulfur, 1%-6% of a corrosion-resistant agent, 2%-8% of an antioxidant and the balance iron and inevitable impurities. According to the alloy drill bit material and the preparation method thereof, the vanadium, the titanium has strong tendency to forming stable carbides, the strength, the hardness of a drill bit can be remarkably improved, and the chromium and the nickel are strong in corrosion resistance under oxidation and reduction environments; and the wear-resistant and corrosion-resistant high-performance drill bit with the high strength and the high-hardness is prepared, so that the high requirements on the drill bit in the petroleum drilling and production work are met.

Description

technical field [0001] The invention relates to the technical field of alloy material preparation, in particular to an alloy drill bit material used for oil drilling and a preparation method thereof. Background technique [0002] The role of petroleum in the national economy Petroleum is an important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and less pollution to the atmosphere after combustion. Fuel oil extracted from petroleum is the main fuel for various kilns in transportation vehicles, power station boilers, metallurgical industry and building materials industry. Liquefied petroleum gas and pipeline gas, which use petroleum as raw material, are high-quality fuels used by urban residents. Airplanes, tanks, ships, rockets, and other spacecraft also consume large amounts of petroleum fuel. Therefore, many countries have listed oil as a strategic material. [0003] The oil drill bit is an impor...
