Definitions

  • the existing drilling equipment for well drilling generally includes: lifting systems, rotary systems, circulation systems, power equipment, transmission systems, control systems, bases and other auxiliary equipment.
  • the power equipment is set on the well, and the power is transmitted to the drill bit through the drill pipe.
  • the deeper the drill the longer the drill pipe required.
  • the driving power of the drilling equipment needs to be increased, and the stress on the drill pipe increases.
  • greater friction occurs between the mud, the wall of the well, and the drill pipe. The rate of drilling slows down and the rate of drill pipe damage increases.
  • the purpose of the present invention is to provide a drilling equipment with high drilling efficiency, low cost, not easy to damage and high rate of well formation.
  • FIG. 1 is a schematic diagram of a drilling apparatus according to the present invention. Best Mode of the Invention
  • the drilling equipment of the present invention has a submersible motor 12 as a power unit, which transmits torque to the drill bit 1 through a speed reducer 8 and a drill pipe 2.
  • the housing of the reducer 8 and the housing of the submersible motor 12 are fixedly connected in a sealed manner through a connection plate 11.
  • a refrigeration device 14 is provided, and its shell is connected to the shell of the submersible motor 12 in a sealed and fixed manner through a connection plate 13.
  • the refrigeration equipment 14 starts when the water in the submersible motor 12 is 75 ° C or higher, and is used to cool the water in the submersible motor 12 so that the motor 12 can work normally.
  • two resistance arms 9, 10 are fixed symmetrically. The two resistance arms 9, 10 cannot rotate relative to the stator portion of the motor 12.

Abstract

L'invention concerne un équipement de forage comprenant une machine submersible (12) transmettant un couple à une tige de forage (2) par le biais d'un réducteur de vitesse (8). Un équipement de refroidissement (14) est fixé sur l'extrémité supérieure de la machine submersible (12) et une pompe haute pression (16) est reliée à l'extrémité supérieure de l'équipement de refroidissement. Une boîte d'engrenages (5) cannelée vient entre la tête de forage (1) et le réducteur de vitesse (8). Sur chaque axe de déplacement de la boîte d'engrenages (5) cannelée se trouve une lame (3, 4) destinée à canneler la paroi de forage ainsi que deux barres de blocage (9, 10) fixées sur la machine submersible (12). Ces deux barres de blocage peuvent s'accoupler à la paroi de forage cannelée par les deux lames (3, 4) de manière à éviter que la machine submersible (12), l'équipement de refroidissement (14) et la boîte d'engrenages (5) ne tournent avec la paroi pendant le forage.
