• Hersteller:
  American Augers
• Modell:
  DD-60/R2
• Rig Größe:
  50,001 - 100,000 lbs pullback

-MANUFACTURED by the world's most experienced builder of directional drills

-HIGH ROTARY TORQUE turns very large reamers in long bores (12,000 Ib ft, 16 300 Nm)

-MUD FLOW CAPACITY is enough to run large mud motors at peak performance (up to 200-500 GPM, 756-1 890 lit/min)

-EXCLUSIVE H-BEAM hold down, the most effective system available, installs and removes quickly

-INDEPENDENT CONTROLS and hydraulic circuits for thrust/pullback, torque and mud flow permits simultaneous full power operation

-SELF CONTAINED for easy movement and setup

-RACK AND PINION thrust/pullback is much stronger than chain and requires virtually no maintenance. It is a positive drive design that eliminates the stretch and slap associated with chain drive systems

-FIELD PROVEN PIPE HANDLING with remote control hydraulic crane

-WIRELINE COMMUTATOR for speedy hookup of wireline guidance equipment

-FACTORY DIRECT SERVICE for fast support by knowledgeable technicians

-MATCH UP WITH MUD SYSTEMS designed and built by American Augers such as MP-300LC or MP-400EWLC

DRILLING FLUID SYSTEMS

MUD MIXING AND PUMPING Match the DD-60R2 with our MP-300LC or MP-400EWLC. The MP-3OOLC is rated at 300 GPM at 1500 psi (1134 IiVmin at 103.4 bar.) The large capacity tank, 6,000 gallons (22,680 litres) keeps the rig operating without downtime to mix mud. Aventuri together with a centrifugal pump mixes each bag of bentonite in less time, another productivity booster. For greater mud capacity, consider the MP-400EWLC with the Ellis Williams Co, mud pump.

FLUID RECYCLING AND CLEANING To minimize bentonite use and prolong equipment life, consider the use of an American MCMdOO or MCM-1000 mud cleaning system. Returned drilling fluid is pumped into the mud cleaner where sand and other solids are removed. This prolongs the life of all parts which are in contact with the drilling fluid, and can significantly reduce the use of bentonite.
