Skid Mounted Logging Unit

EngineCAT/Mtu/ Cummins

Max. Logging Depth7000m

Max. Pulling Capacity65KN


Product Brief Introduction:
skid mounted logging unit working principle: The engine takes power to drive three hydraulic pumps. The hydraulic pumps are mounted to the three-port pump drive. The pump drive drives the winch system hydraulic pump (closed-loop variable displacement piston pump), generator system hydraulic pump (closed-loop variable displacement pump) and auxiliary system hydraulic pump (gear pump). The winch hydraulic pump drives the winch motor and delivers the power to the reel through gearbox and chains so as to achieve the in-hole and out-hole operation. The generator hydraulic pump drives the generator motor to provide power for the generator. The auxiliary hydraulic pump supplies power for the levelwind arm and hydraulic oil cooler. This unit is equipped with different style logging cable, which can meet different well depth testing requirements。
