Abstract
The invention relates to an oil exploration explosive placing drill bit. A primary drill bit, a secondary drill bit and a three-level drill bit are sequentially arranged on the output end part of a motor fixing cylinder; the primary drill bit is fixed to the outer wall of the output end part of the motor fixing cylinder; the secondary drill bit is provided with an extending mounting end part which is embedded into the primary drill bit; the three-level drill bit is positioned on the lower part of the secondary drill bit; a telescopic explosive placing cylinder is arranged in the motor fixing cylinder; a lubricating oil groove which is downwards inclined is formed in the side wall of each of the primary drill bit and the secondary drill bit; an explosive output opening is formed in the tail end of the telescopic explosive placing cylinder. The oil exploration explosive placing drill bit is simple in structure and reasonable in design; due to the fact that the three-level split type design is adopted, the lubricity and the operability of the drill bit are greatly improved; meanwhile, due to the fact that explosive can be accurately placed in the telescopic explosive placing cylinder, the time for placing the explosive for a second time is avoided, the exploration efficiency is improved, and the oil exploration explosive placing drill bit has high practical value.
