Abstract

The invention discloses a turbine drilling tool motor with emergency stop mechanisms. The turbine drilling tool motor comprises an upper connector, a lock nut, a turbine motor spindle, a turbine motor shell, a spindle adjusting washer, a shell adjusting washer, a radial righting bearing static ring, a radial righting bearing movable ring, a turbine stator and a turbine rotor. The lock nut, the spindle adjusting washer, the radial righting bearing movable ring and the turbine rotor are sequentially assembled from top to bottom to form an internal integral body which can rotate along with the turbine rotor; the upper connector, the turbine motor shell, the shell adjusting washer, the radial righting bearing static ring and the turbine stator are connected with one another to form a static external internal body or an external integral body which can rotate along with drilling collars at low speeds; an annular drilling fluid channel is formed between the internal integral body and the external integral body; clamp groove structures are arranged on the side walls of the annular drilling fluid channel and are positioned between the lock nut and the upper connector, and an annular flange is arranged at the bottom of the outer wall of the lock nut. The turbine drilling tool motor has the advantages that the turbine drilling tool motor can bring convenience for handling drilling complication or drilling accidents, and accordingly loss due to drilling complication or the drilling accidents can be reduced.

Description

technical field [0001] The invention relates to a turbodrilling tool, in particular to a turbodrilling tool motor with an emergency stop mechanism, and belongs to the technical field of drilling equipment. Background technique [0002] Turbine drilling tool is a downhole dynamic drilling tool commonly used in oil and gas and geological drilling. Its working principle is to convert the liquid pressure energy of drilling fluid into mechanical energy, and drive the drill bit to rotate to break the bottom rock. During the drilling process, drilling complications or accidents may occur due to many unpredictable reasons, especially when the drill bit connected to the main shaft of the turbine motor is stuck, the shell of the ordinary turbodrill rotates and the drill bit cannot rotate accordingly, the turbodrill The idling of the casing will bring difficulties in dealing with complicated drill stuck or accidents, delay the opportunity of emergency repair, and expand direct or indir...
