Embodiment Construction

[0015] see figure 1 and figure 2 , figure 1 and figure 2 It is a structural schematic diagram of a roller cone bit swirl nozzle according to one embodiment of the present invention. The roller cone bit swirl nozzle is composed of a swirl nozzle main body 1 , a guide block 3 , a bump 5 and a retaining ring groove 4 . The inner wall of the swirl nozzle main body 1 made of hard alloy is evenly distributed with three oblique guide blocks 3, which guide the fluid flowing through the guide blocks 3, and the three oblique guide blocks 3 force the fluid to flow through the nozzle to form Swirl, there is a bump 5 at the outer circle of the swirl nozzle of the roller cone bit, which cooperates with the gap on the water eye hole on the drill bit body to prevent the swirl nozzle from rotating due to the reaction force while forming the swirling liquid flow. At the same time, there is a circlip groove 4 on the outer circle of the swirl nozzle of the roller cone bit, and the swirl nozz...

Abstract

The invention relates to a swirl nozzle for drilling. The swirl nozzle is simple in structure, convenient to install and difficult to drop. According to the technical scheme, the swirl nozzle is arranged on a drill bit and comprises a swirl nozzle main body; three guide blocks are arranged on the inner wall of the swirl nozzle main body; the guide blocks are three oblique guide blocks distributed uniformly; a lug is arranged on the external circle of the swirl nozzle of a roller bit, and a clamping spring groove is formed on the external circle of the swirl nozzle of the roller bit; and a spiral screw thread is arranged on the external circle of a polycrystalline diamond compact (PDC) bit.

Description

1. Technical field: [0001] The invention relates to a nozzle for a drill bit in petroleum geological drilling, in particular to a swirl nozzle for drilling. 2. Background technology: [0002] There are many types of nozzles available. The first type is the ordinary nozzle of the roller cone bit; the second type is the extended nozzle of the roller cone bit; the third type is the medium-length nozzle of the roller cone bit; the fourth type is the pulse nozzle of the roller cone bit; the fifth type is the nozzle of the PDC bit. They are made of tungsten carbide and can all function as nozzles, but their structures are complex and inconvenient to install. 3. Contents of the invention: [0003] In order to solve the shortcomings in the above background technology, the present invention provides a swirl nozzle for drilling, which has a simple structure, is easy to install, and is not easy to fall off. [0004] In order to achieve the above object, the technical scheme adopted...
