Embodiment 1

[0024] Referring to the accompanying drawings, the matrix-containing diamond drill bit impregnated with pores for geological exploration in this embodiment includes a steel body 5 and a matrix 1, the matrix 1 is located on the steel body 5, and an inner water tank is provided on the steel body 5 2. Nozzle 3, outer water tank 4, diamond 6 and air holes 7 are arranged in the carcass 1.

[0025] In this embodiment, the pores are spherical in shape with a diameter of 0.3-0.8 mm, and are evenly distributed in the working layer of the carcass. Among them, the total volume of pores accounts for 12.3% of the total volume of the carcass working layer.

[0026] Take the 8mm working layer carcass of the 75 / 49 rope drill as an example.

[0027] The manufacturing process includes the following steps:

[0028] (1) Weigh NaHCO 3 1.6g, glycerol 0.9g, the NaHCO 3 Add glycerin and stir evenly;

[0029] (2) Add 96.3g of matrix formula powder and 10.7g of diamond (GE960, particle size 30-40...

Embodiment 2

[0033] The carcass impregnated diamond drill bit with pores in this embodiment includes a steel body 5 and a carcass 1, the carcass 1 is located on the steel body 5, and the steel body 5 is provided with an inner water tank 2 and a nozzle 3 , The outer water tank 4, the carcass 1 is provided with diamonds 6 and air holes 7.

[0034] In this embodiment, the pores are spherical in shape with a diameter of 0.6-1.0 mm, and are evenly distributed in the working layer of the carcass. Among them, the total volume of pores accounts for 23.5% of the total volume of the carcass working layer.

[0035] The manufacturing process includes the following steps:

[0036] (1) Weigh (NH 4 ) 2 SO 4 1.1g, glycerol 0.4g, the weighed (NH 4 ) 2 SO 4 Add glycerin and stir evenly;

[0037] (2) Add 96.3g of matrix formula powder and 10.7g of diamond (GE960, particle size 30-40 mesh), among which, the matrix formula powder is: by mass ratio, 663 bronze powder: iron powder: tin powder: Nickel p...

Abstract

The invention provides a casing gas containing hole impregnated diamond bit for geological exploration and a manufacturing process. The casing gas containing hole impregnated diamond bit comprises a steel body and a casing. The casing is located on the steel body. The steel body is provided with inner water grooves, water gaps and outer water grooves. Diamonds and gas holes are formed in the casing. The invention further provides the manufacturing process of the casing gas containing hole impregnated diamond bit for geological exploration. By the adoption of the casing gas containing hole impregnated diamond bit for geological exploration, tiny broken blocks are generated by the casing along with the increase of pressure in the drilling process, old diamonds fall in time, new diamonds are exposed continuously, the drilling speed is increased, and drilling efficiency is improved.

Description

technical field [0001] The invention relates to a drill bit and a manufacturing process, in particular to a matrix-containing pore-impregnated diamond drill bit for geological exploration and a manufacturing process. Background technique [0002] At present, the conventional impregnated diamond bit is used for extremely hard and weakly abrasive slippery formations, and the diamond in the working layer of the matrix is ​​not easy to cut out, resulting in extremely slow or even no footage, and low drilling efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a matrix air hole-impregnated diamond drill bit for geological exploration which is suitable for extremely hard and weakly abrasive slippery formations and can improve drilling speed and drilling efficiency and its manufacturing process. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] The car...
