Abstract

The invention relates to a well-drilling acceleration tool. The well-drilling acceleration tool comprises a hollow shell, wherein a connecting head is fixedly arranged at the top of the shell and is connected with a drill column, an annular concave table is formed in the shell, a torsion transfer assembly is arranged in the annular concave table and comprises a hollow torsion shaft and a spiral torsion spring piece, one end of the spiral torsion spring piece is fixedly connected with the torsion shaft, the other end of the spiral torsion spring piece is fixedly connected with the shell, and the lower end of the torsion shaft is connected with a drill bit. According to the well-drilling acceleration tool, when the drill bit is in a viscous state or in a non-viscous state, the huge torque caused by the drill column is buffered and absorbed by virtue of the deformation of the drill bit, so that the drill bit and the drill column are protected, meanwhile, the damage of the drill bit can bereduced, the fault rate of the drill bit is reduced, and the well-drilling process is relatively stable.

Description

technical field [0001] The invention relates to the technical field of drilling bit supporting equipment, in particular to a drilling speed-increasing tool. Background technique [0002] With the development and exploration of various energy blocks in my country, the wells are drilled deeper and deeper, and the formations encountered are becoming more and more complex. The stick-slip phenomenon is the main restrictive factor for the low ROP and low drilling efficiency of PDC bits in complex formations. This phenomenon is more obvious and severe especially in hard formations and deep well drilling. [0003] The following problems exist during the drilling process: [0004] 1) When the torque provided by the drill string to the drill bit is less than the shear limit of the rock on the working face, the drill bit stops rotating with the drill string, and the drill bit is in a viscous state; [0005] 2) When the torque accumulated in the drill string is greater than the rock s...
