Disc spring type axial vibration acceleration tool

Abstract

The invention relates to a disc spring type axial vibration acceleration tool. The problem that an existing shock absorption effect provided only by hydraulic pressurization is not obvious and a drillbit is prone to drill to unstable is mainly solved. The disc spring type axial vibration acceleration tool is characterized in that the lower end of an upper connector (1) is in threaded connection with an outer shell (3); a lower connector (4) is mounted on a lower boss in the outer shell (3), a lining pipe (2) is mounted in a concave platform at the top end of the inner cavity of the upper connector (1), a disc spring (6) sleeves the lining pipe (2), a nozzle (5) is mounted in the concave platform in the middle of the middle of the upper end of the lower connector (4), and the upper end ofthe lower end of the disc spring (6) abut against the upper end face of the inner cavity of the upper connector (1) and the upper end face of the lower connector (4) respectively. According to the disc spring type axial vibration acceleration tool, the drilling pressure can be effectively applied to the drill bit, the mechanical drilling speed is improved, and stable drilling is facilitated.

Description

technical field [0001] The invention relates to the technical field of oil and gas field exploitation engineering, in particular to a disc spring type axial vibration speed-increasing tool. Background technique [0002] In the process of drilling horizontal wells at home and abroad, hydraulic pressurizers are used to increase the rate of penetration. The existing technology only uses hydraulic principles to achieve hydraulic flexible pressurization, but only relies on the shock absorption provided by hydraulic pressurization. The effect is not obvious, resulting in unstable drilling of the drill bit. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the problems existing in the background technology that the damping effect provided by hydraulic pressurization alone is not obvious and easily lead to unstable drilling of the drill bit, and to provide a disc spring type axial vibration Speed-up tool, the disc spring...
