A trigger mechanism is provided for a passive rotating jointed tubing injector having gripper blocks for moving connected, segmented oilfield tubulars axially into or out of horizontal, extended-reach oil and natural gas wells that may contain pressurized fluid or gas to complete for production, work over and service the wells, utilizing an operation commonly known as snubbing. The trigger mechanism can open the gripper blocks when a tapered upset section of increasing diameter on the tubulars is encountered that would not otherwise fully open and operate the gripper blocks.

Jointed pipe injector trigger mechanism

A passive rotating jointed tubular continuous snubbing injector is provided for moving connected, segmented oilfield tubulars axially into or out of horizontal, extended-reach oil and natural gas wells that may contain pressurized fluid or gas to complete for production, work over and service the wells, utilizing an operation commonly known as snubbing. The injector can include variable diameter gripping mechanisms that, in combination with linear drive mechanisms, can apply radial force onto and over a certain length of the tubular, of the tubular string, and onto and over a coupling or tool joint connecting tubulars together while moving the tubular string axially into or out of the well. Further, the injector may rotate in response to the rotation of tubulars while the injector is moving the tubular string into or out of the well.

An apparatus for handling pipes in a derrick and racking the pipes on a pipe racking assembly mounted on the derrick is provided to improve the stability of transferring pipes during a round trip operation.

Apparatus for handling and racking pipes

An apparatus and method for handling pipes in a derrick and racking the pipes on a pipe racking assembly mounted on the derrick. The apparatus includes a rotatable gate assembly rotatably mounted on the pipe racking assembly. The rotatable gate assembly includes a collar rotatably mounted to a first end of a rotatable pipe support. A pipe manipulator arm is pivotably mounted on a second end of the rotatable gate assembly. The collar defines a gate for securing an upper portion of the pipe stand. A pipe mount is mounted to a distal end of the arm for holding the pipe stand for transport between the derrick and the gate, and between the gate and the pipe rack. After the arm secures the pipe stand into the gate from the derrick, a drive mechanism rotates the rotatable gate assembly to a rack facing position from the derrick facing position such that the arm may transport the pipe between the gate and the pipe rack.

The apparatus includes a rotatable gate assembly mounted on the pipe racking assembly. The rotatable gate assembly includes a collar rotatably mounted to a first end of a shaft and an arm pivotably and rotatably mounted on a second end of the shaft. The collar defines a gate for securing an upper portion of the pipe stand. A first securing means mounted to a second end of the arm secures the mid-portion of the pipe stand and a second securing means mounted to the first securing means secures the lower portion of the pipe stand. After the arm secures the pipe stand from the derrick, a drive mechanism mounted to the shaft rotates the rotatable gate assembly such that the arm may rack the pipe on the pipe racking assembly.
