Rating Workover Rig Derrick

  • Conventional
  • Auto-transportable

The difference is that conventional ones have greater capacity and can work deep well workover. Trucking teams have a set of winch – CI engines mounted on a trailer. Trucking equipment are easier to move to another location.

2. Circulation System

Tanks, fluid movement, main and auxiliary pumps, tube Vertical (stand pipe) hose, movement, or return flow line (Flow Line), Solids Control Equipment, mass settlement, degassing and gas separators.

3. Rotation System

Rotary table and accessories, pipe work (drill pipe), drill collar, heavy line (Hevi-wate), drill, kelly and accessories, swivel (swivel).

4. Power System
Prime movers, generators, power transmission.

Prime movers
Generally are internal combustion, the fuel being used Gas Oil. These motors can be coupled directly with the computer or charge coupled to generators to supply electrical power.

Change the mechanical power developed by the prime movers in electric current and are generally AC.

Power Transmission
The power generated by the prime movers to be transmitted to the teams to provide movement. If the equipment is mechanical, this power is transmitted directly from the prime mover to the team. If the equipment is electrical, mechanical engine power is converted into electric power generators, then this electric power is transmitted to the electric motors attached to the equipment, making his move.

5. Well Control System
Preventors Valves (BOP’s), cancel or spherical, rams or pipe rams, blind rams or rams (Blind Rams), or Rams Rams Shear (Shear Rams), Unit pressure accumulator, choke manifold (kill manifold) manual or remote choke (super-choke), Line of killing (kill line) Line choke (choke line), relief valve (HCR), auxiliary valves (kelly cock, internal BOP).
