Drill bit for petroleum geological exploitation

Abstract

The utility model relates to the technical field of drill bits, and discloses a drill bit for petroleum geological exploitation, which comprises a main body, the top end of the main body is fixedly connected with a fixing plate, the bottom end of the main body is fixedly connected with a fixing cylinder, the outer side of the fixing cylinder is slidably connected with a sliding cylinder, and grooving devices are annularly arranged on the side surface of the main body at equal intervals. Due to the fact that the spring is arranged, when the device is used, the spring can relieve hard impact force in the downward drilling process of the drill bit through the elasticity of the spring, and due to the fact that the grooving device and the drilling corners are detachable, in the long-time using process, the grooving device can be used for grooving the drill bit. When one or more grooving devices and drilling corners are worn to be scrapped, only one grooving device and one drilling corner need to be taken out of the clamping groove or the mounting groove, and then brand new accessories are mounted, so that one part of the device is replaced, and the use cost is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, and more particularly to a drill bit used in petroleum geological development. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. It is a very important energy source in the national economy. Compared with coal, petroleum has the advantages of high energy density, convenient transportation and storage, and low pollution. Fuel oil extracted from petroleum is the main fuel for transportation, power plant boilers, metallurgical industry and building materials industry. In the process of petroleum extraction, oil drill bits are very important tools.

[0003] The shortcomings of the existing technology are: the existing drill bit is not convenient for alleviating the hard impact force during the drilling process. When the drill bit just starts to drill, the impact force is mostly large, and the drill bit directly impacts the ground, which easily causes a high risk of damage to the drill bit. Since the drill bit is subject to large wear and tear during drilling, and most of the existing drill bits are installed in an integral manner, when the drill bit is severely worn, the entire drill bit can only be replaced. The worn parts of the drill bit are only the edge drill corners and the bottom contact drill bit. The overall replacement increases the cost of using the drill tool. Therefore, we propose a drill bit for petroleum geological development to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a drill bit for petroleum geological development to solve the problems existing in the above-mentioned background technology.
