Petroleum exploitation drill bit

Abstract

The invention discloses a petroleum exploitation drill bit which comprises a connecting plate, a drill bit body, a left guide column and a right guide column. A through hole is formed in the center ofthe connecting plate, a connecting rod penetrates the through hole, the lower end of the connecting rod is connected with the drill bit body, bolt holes are formed in two ends of the connecting plate, the connecting plate can be connected with drill rigs, compression-resistant plates are fixedly mounted on the lower end surface of the connecting plate, an anti-vibration spring sleeves the connecting rod and is arranged between the compression-resistant plates and the upper end surface of the drill bit body, and the left guide column and the right guide column are arranged on two sides of theconnecting rod and are arranged between the compression-resistant plates and the upper end surface of the drill bit body. The petroleum exploitation drill bit has the advantages that the petroleum exploitation drill bit is novel in structural design and has excellent compression-resistant, abrasion-resistant and anti-vibration functions, deformation abrasion phenomena of the drill bit body can beeffectively prevented, the service life of the petroleum exploitation drill bit can be prolonged, and the petroleum exploitation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a drill bit for petroleum exploitation. Background technique [0002] Petroleum is a fluid mineral buried deep in the bottom. In the national economy, petroleum is a very important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and low pollution. Fuel oil extracted from petroleum is transported Tools, power plant boilers, metallurgical industry and building material industry are the main fuels, so many countries have listed oil as a strategic material. [0003] In the process of oil extraction, the oil drill bit is a very important tool, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. The drill bit in the prior art has certain wear resistance, but its working process is anti-seismic. The effect is poor, resulting in a short service...

[0003] In the process of oil extraction, the oil drill bit is a very important tool, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. The drill bit in the prior art has certain wear resistance, but its working process is anti-seismic. The effect is poor, resulting in a short service life, therefore, it is necessary to improve
