Abstract

The invention relates to the technical field of machinery, and discloses an oilfield drill bit with a self-washing heat-dissipation function. The drill bit comprises a drill bit shell, wherein the interior of the drill bit shell is provided with a roll shaft, drill bit shell and the roll shaft are connected with a drill bit body, the top of the drill bit body is provided with a spray head, the spray head is provided with a spray pipeline, the top of the drill bit shell is provided with a rotating steel pipe, the top of the drill bit shell is provided with a threaded connecting port connected with the rotating steel pipe, a cooling water storage pipe is arranged in the rotating steel pipe, a collecting water tank is connected between the bottom of the cooling water storage pipe and the spray pipeline, and a water inlet is formed in the top of the cooling water storage pipe. According to the oilfield drill bit with the self-washing heat-dissipation function, the cooling water storage pipe is arranged in the rotating steel pipe to be connected with the spray head at the top of the drill bit body, frictional heating occurs when the drill bit works, the effect of heat dissipation is achieved, when the drill bit makes contact with the hard ground, the effect of earth softening is achieved, and the employee operation is easier.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an oilfield drill bit with self-cleaning and heat dissipation functions. Background technique [0002] Oil field extraction refers to the act of digging and extracting oil in places where oil is stored. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. Oil field drill bit is an important tool for oil field drilling, and it is used to drill oil when oil is extracted. [0003] With the development of oilfield mining, the consumption of oilfield drill bits is increasing. The solid rock and soil deposits reduce the quality of the drill bit. At the same time, the long-term operation, the friction temperature of the drill bit is high, and it is prone to chipping, which greatly affects the mining. Work. The price of oilfield drill bits is high, and the cost of frequent drill bi...
