Abstract
A connector permits separation of a submergible pumping system from its deployment system. The connector includes an upper assembly and a lower assembly that are connected by shear screws. A hydraulic separation mechanism is used to shear the shear screws and separate the upper and lower assemblies from a remote location.
Claims15
A system for connecting a submergible pumping system to a deployment system and for selectively releasing the submergible pumping system from the deployment system, comprising:
- a submergible pumping system;
- a coil tubing deployment system comprising:
- a coil tubing;
- and
- a power cable disposed within the coil tubing to supply power to operate the submergible pumping system;
- and
- a connector connecting the coil tubing deployment system with the submergible pumping system, the connector having:
- an upper connector assembly;
- a lower connector assembly attached to the upper connector assembly;
- and
- a separator mechanism that may be remotely actuated to separate the upper connector assembly from the lower connector assembly.
A system for connecting a submergible pumping system to a deployment system and for selectively releasing the submergible pumping system from the deployment system, comprising:
- a coil tubing deployment system;
- a downhole completion;
- and
- a connector connecting the coil tubing deployment system with the downhole completion, the connector having:
- an upper connector assembly;
- a lower connector assembly;
- a shear pin connecting the upper connector assembly to the lower connector assembly;
- and
- a separator mechanism that may be remotely actuated to separate the upper connector assembly from the lower connector assembly, wherein the separator mechanism comprises a hydraulic line disposed through the upper connector assembly and a discharge area on the lower connector for receiving pressurized hydraulic fluid from the hydraulic line.
A system for connecting a submergible pumping system to a deployment system and for selectively releasing the submergible pumping system from the deployment system, comprising:
- a coil tubing deployment system;
- a downhole completion;
- and
- a connector connecting the coil tubing deployment system with the downhole completion, the connector having:
- an upper connector assembly;
- a lower connector assembly attached to the upper connector assembly;
- a plurality of motor conductors that extend through a plug, the plug being separable and having a first plug portion disposed in the upper connector assembly and a second plug portion disposed in the lower connector assembly;
- and
- a separator mechanism that may be remotely actuated to separate the upper connector assembly from the lower connector assembly, wherein the separator mechanism comprises a hydraulic line disposed through the upper connector assembly and a discharge area on the lower connector for receiving pressurized hydraulic fluid from the hydraulic line.
