Abstract

The invention discloses an efficient turbine drill which comprises a thrust bearing, a main shaft, a middle bearing, a turbine stator and rotor assembly, a lower portion bearing, an alloy bit and an outer shell. The main shaft is sleeved with the outer shell, the upper portion, the middle portion and the lower portion of the main shaft are sequentially provided with the thrust bearing, the middle bearing and the lower portion bearing, the thrust bearing, the middle bearing and the lower portion bearing are all clamped between the main shaft and the outer shell, the upper portion and the lower portion of the main shaft are both of hollow structures, a suspension ring is arranged on the outer wall of the main shaft, the suspension ring enables the main shaft to be suspended inside the outer shell through the thrust bearing, the turbine stator and rotor assembly is arranged on the lower portion of the middle bearing, a water inlet communicated with the interior hollow structure is formed in the position, arranged on the upper portion of the turbine stator and rotor assembly, of the outer wall of the main shaft, a water outlet is formed in the position, arranged on the lower portion of the turbine stator and rotor assembly, of the main shaft, and the alloy bit is connected at the bottommost end of the main shaft. The efficient turbine drill is reasonable in structure, efficient, and high in safety and practicability.

Description

technical field [0001] The invention relates to a petroleum drilling tool, in particular to a high-efficiency turbo drilling tool, which belongs to the field of petroleum machinery. Background technique [0002] The working condition of the turbodrill is relatively harsh in the underground. The drilling mud flow directly hits the turbine blade at high speed to obtain energy, thereby driving the drill bit connected to it to rotate the well. The turbodrill mainly includes a turbine stator, a turbine rotor, a main shaft, and a thrust Bearings, middle bearings, lower bearings and housings. When drilling, the drill pipe does not move, and the turbine rotor drives the main shaft to rotate, so it has many advantages such as high drilling speed, high efficiency and short drilling time, and reduces the wear and accidents of the drill pipe and casing. [0003] Today's turbodrills often lead to insufficient utilization of liquid potential energy and clogging of the rotor due to the l...
