A new type of oil drill bit

Abstract

The invention discloses a novel petroleum drill bit comprising a shell. The upper end of the shell is provided with a main drill. The novel petroleum drill bit also comprises a guide drill mounted on the main drill. An opening is formed in the top end of the main drill, and the size of the opening is the same as that of a wide section at the bottom end of the guide drill. Two ends of the guide drill are provided with clamping devices. Each clamping device comprises a clamping fastener, a spring for connecting the clamping fastener and the inner wall of the main drill and a directional frame. Two sides of the guide drill are provided with bosses. Multiple groups of groove holes fitting the bosses are formed in each clamping fastener. The novel petroleum drill bit is very convenient to implement due to the scientific and reasonable structure, can adapt to different terrains through changing the guide drill in the main drill to different specifications, is simple and easy in use and is capable of reducing the cost because manpower and financial resources for replacing the drill bit are saved.

Description

technical field [0001] The invention relates to the field of petroleum exploration, in particular to a novel petroleum drill bit which can adapt to various environments. Background technique [0002] Petroleum is one of the most important and indispensable non-renewable energy sources on the earth. With people's excessive exploitation, shallow oil has become more and more scarce, and people have gradually shifted the direction of exploitation to the ocean and deep layers. As an indispensable equipment in oil extraction, drill bits have been made more and more advanced improvements by people. It has become more and more suitable for deep mining, but people often change the existing drill bits in terms of material and hardness, which does not reduce the production cost of the drill bit, but the cost is getting higher and higher. [0003] In the process of deep drilling, the guide drill is indispensable. Without the guidance of the guide drill, not only the desired destination...

Problems solved by technology

With people's excessive exploitation, shallow oil has become more and more scarce, and people have gradually shifted the direction of exploitation to the ocean and deep layers. As an indispensable equipment in oil extraction, drill bits have been made more and more advanced improvements by people. It has become more and more suitable for deep mining, but people often change the existing drill bits in terms of material and hardness, which does not reduce the production cost of the drill bit, but the cost is getting higher and higher

[0003] In the deep drilling process, the pilot drill is indispensable. Without the guidance of the pilot drill, not only the desired destination will not be reached, but the drilling time will be increased, the service life of the drill bit will be excessively consumed, and a lot of manpower and material resources will be consumed Financial resources, resulting in an invisible increase in costs several times

[0004] And in different terrains and geology with different hardness, the specifications of the required guide drills are not the same, and it is necessary to prepare and replace a large number of guide drills with different specifications, which increases the cost of drilling time and costs for preparing different guide drills for no reason. a lot of money
