DYNADRILL [3 records]

Record 1 2011-05-17

English

Subject field(s)
  • Equipment (Oil and Natural Gas Extraction)
DEF

A drill developed in the U.S.S.R. for drilling deep oil wells. One type is designed as a turbine and driven by the drilling fluid which is circulated at high pressure.

CONT

There are two types of turbodrill or down-hole mud motor : the turbine, of which there are about six successful types, and the Dynadrill, a Moyno pump operating in reverse, consisting of a spiral shaft contained within a rubber sleeve.... The down-hole turbine is basically similar to a gas turbine having a multi-stage stator and rotor.

CONT

When a turbodrill is used, rotary motion is imparted only at the bit; therefore, it is not necessary to rotate the drill stem. Although straight holes can be drilled with the tool, it is used often in directional drilling.

  • Outillage (Extraction du pétrole et du gaz)
DEF

Foreuse constituée d'une turbine actionnée par la boue de forage.

CONT

La turbo-foreuse est une turbine à étages multiples entraînant directement les trépans à molettes [...] Elle est actionnée par la circulation de la boue, dont le débit et la pression sont adaptés à cet usage. Les tiges sont alors immobiles ou tournent lentement pour supporter la réaction du couple moteur.

OBS

A trade name for a downhole motor driven by drilling fluid that imparts rotary motion to a drilling bit connected to the tool, thus eliminating the need to turn the entire drill stem in order to make hole.

OBS

There are two types of turbodrill or down-hole mud motor : the turbine, of which there are about six successful types, and the Dynadrill, a Moyno pump operating in reverse, consisting of a spiral shaft contained within a rubber sleeve.

Record 3 1998-04-20

English

Subject field(s)
  • Motors (Machinery)
  • Oil Drilling
DEF

A turbodrill or Dyna-Drill.

CONT

When a downhole motor is used, it is attached to the lower end of the drill string; then the bit is attached to the bottom end of the downhole motor. The drilling motor rotates the bit, rather than the bit being rotated by the drill pipe string.

CONT

There are two types of turbodrill or down-hole mud motor : the turbine, of which there are about six successful types, and the Dynadrill, a Moyno pump operating in reverse, consisting of a spiral shaft contained within a rubber sleeve.... The down-hole turbine is basically similar to a gas turbine having a multi-stage stator and rotor.
