Drill bit easy to disassemble and assemble and used for petroleum exploration and exploitation

Abstract

The invention relates to the technical field of petroleum exploration, in particular to a drill bit easy to disassemble and assemble for petroleum exploration and exploitation. The drill bit comprises a drill bit body, a drill bit tail end and a mounting sleeve, wherein the whole drill bit tail end is in a cube shape, the drill bit body is fixedly arranged at the center of one surface of the drill bit tail end, and a fixing device used for fixing the drill bit tail end is arranged in the drill bit tail end; and the whole mounting sleeve is in a cuboid uncovered box shape, and the closed surface of the mounting sleeve is provided with a releasing device used for being in contact with a fixing device in the tail end of the drill bit for fixing. The drill bit for petroleum exploration and exploitation can meet the requirement for convenient replacement of the drill bit for petroleum exploration and exploitation, the fixing degree between the drill bit for petroleum exploration and exploitation and the mounting sleeve is enhanced due to the fact that the fixing mode is double fixing, falling is prevented, and safety is improved, the two fixing modes are performed and cancelled at the same time, so that the time required for replacing the drill bit for petroleum exploration and exploitation is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to an easily disassembled drill bit for petroleum exploration and development. Background technique [0002] Petroleum exploration, as the main means of understanding the underground geological conditions and various oil and gas resource reserves, deserves high attention and resource supply. Petroleum exploration methods are mainly divided into four types: geological method, geophysical method, geochemical method and drilling method. Drilling method is an important means that must be used in petroleum exploration, from investigation, discovery of oil and gas to oil and gas exploitation. drilling method. [0003] Most of the commonly used drill bits for oil exploration on the market are not easy to disassemble and assemble, and what’s more, they cannot be replaced. Spending a lot of unnecessary time on disassembly and assembly operations will slow down the progress of...
