Abstract
A mono-rail boom supported articulated pipe well service line for the transfer of pressurized fluids from service vehicles to petroleum wellheads for the treatment and stimulation of production oil wells. The boom is mounted on a truck, trailer, or other suitable mobile transport, and the articulated pipe line which comprises a plurality of pipe sections interconnected by swivel joints to provide the required rotational freedom and flexibility, is suspended from the boom by trolleys to facilitate extension and retraction of the pipe line either independently of movement of the boom, or concurrently therewith.
Claims20
A mono-rail boom supported articulated well service line for use in well service operations to interconnect a supply of pressurized fluid to a wellhead, comprising:
- an extendible mono-rail boom having a plurality of boom sections with an inboard boom section mounted on a mobile transport means and with the other boom sections extendible outward from said inboard boom sections;
- means for supporting an outer portion of said boom when said boom is in an extended position;
- an articulated pipe well service line;
- a plurality of trolleys mounted for relative independent movement along the length of said boom with the movement of said trolleys independent of the extendible movement of said boom sections;
- means for connecting said service line to said trolleys for movement of said service line between a retracted position and an extended position when said boom is in an extended position;
- and
- means for disconnecting said service line from said trolleys for supporting said service line on the ground when said service line is at least partially extended.

- an extendible mono-rail boom having a plurality of boom sections with an inboard boom section mounted on a mobile transport means and with the other boom sections extendable outward from said inboard boom section;
- means for supporting an outer portion of said boom when said boom is in an extended position;
- an articulated pipe well service line including a plurality of long pipe sections each substantially the same length as a corresponding one of the boom sections, and a plurality of shorter pipe sections pivotally interconnecting said long pipe sections;
- a plurality of trolleys mounted for movement along the length of said boom;
- means for connecting said service line to said trolleys for movement of said service line between a retracted position and an extended position when said boom is in an extended position;
- and
- means for disconnecting said service line from said trolleys for supporting said service line on the ground when said service line is at least partially extended.
