摘要： A coiled tubing transport unit includes a coiled tubing reel unit, a guide sleeve coupled to the coiled tubing reel unit, and a corresponding arm coupled to the coiled tubing transport unit, wherein the arm is retractable or extendable from the guide sleeve, and a hydraulic cylinder coupled between the coiled tubing reel unit and the transport unit. The arm retracts or extends from the guide sleeve when the hydraulic cylinder is actuated to push or pull against and move the coiled tubing reel unit along a length of the coiled tubing transport unit.

摘要： A multi-axle transport trailer having a plurality of axles includes a suspension comprising air bags associated with each axle, the air bags in communication with an air source, wherein air bags associated with different axles are capable of having different air pressures therein. The trailer further optionally includes a steering system associated with at least one axle, the axle including a tie rod connected between wheels on both ends of the axle, the steering system comprising cylinders configured to articulate the wheels, and a sensing device configured to monitor movement of the tie rod and facilitate actuating the cylinders to turn the wheels.

摘要： An auxiliary dolly attachable to or integral with the rear of a primary trailer includes a first portion attachable to or integral with the primary trailer, a second portion comprising one or more axles with wheels, and a pivot point at which the first portion is coupled to and movable relative to the second portion, and further includes one or more cylinders configured to adjust the first and second portions relative to each other and apportion weight between the primary trailer and the auxiliary dolly. At least one or more booster axle groups and one or more trailer axle groups are configured to shift independently. This allows for efficient and cost-effective load balancing.

摘要： A control system for moving a bottom hole assembly at an end of a coiled tubing string in a wellbore includes a controller configured to move the bottom hole assembly at an initial rate, unless the controller determines that moving the bottom hole assembly at the initial rate causes a predetermined threshold parameter to be reached, whereupon the controller is configured to default to moving the bottom hole assembly at a safe rate.
