Abstract

The invention relates to a regional resonant well drilling device and a well drilling method thereof. The regional resonant well drilling device comprises a rotating disc, a drill pipe, a resonant generating chamber, a main drill bit and four resonant drill bits, the lower end of the drill pipe is connected with the resonant generating chamber, the lower end of the resonant generating chamber is connected with the main drill bit, a water outlet pipe is arranged in the center of the main drill bit, and the four resonant drill bits are distributed around the water outlet pipe and exposed at thebottom end of the main drill bit; two supporting rods are installed on a bottom plate of the resonant generating chamber, a first vibration excitation platform and a second vibration excitation platform are installed at the upper ends of the supporting rods correspondingly, a power supply device and a resonant frequency control center are connected with the first vibration excitation platform andthe second vibration excitation platform correspondingly, the resonant drill bits are all connected to the bottom end of the resonant generating chamber through transmission rods, and the main drill bit and the drill pipe are connected through the water outlet pipe. According to the regional resonant well drilling device, the four resonant drill bits and the main drill bit work alternately for a certain period of time, by cooperating with drilling, rock breaking can be effectively achieved on a hard formation, and the well drilling speed is increased.

Description

Technical field: [0001] The invention relates to the field of drilling engineering, in particular to an area resonance drilling device and a drilling method thereof. Background technique: [0002] Drilling is an important part of oil extraction. Many scientific researchers continue to explore new and effective drilling methods, including laser method, resonance method, arc method, explosion method, electron beam method, electric spark method and so on. Resonance drilling method is one of the important directions of future drilling technology development. Resonance drilling technology can solve the problems of low drilling speed, high drilling cost and serious drill bit wear in hard formations, and greatly improves drilling efficiency. However, this technology is still in the stage of indoor experimental research, and many aspects need to be innovated and optimized. For this new type of drilling method, it is necessary to design a regional resonance drilling method and dri...
