Modular hydraulic packer-and-port system

摘要

Modular hydraulic packer-and-port system and corresponding methods of operation. The system may be installed for temporary, semi-permanent, or permanent deployments. The system and method may provide for hydraulic isolation of target zones in a well while allowing pass-through tubes to the target zones for taking samples, inserting monitoring sensors, and the like.

主权项

1. A modular hydraulic packer-and-port system comprising:
a tubular riser section; a tubular spacer section; a tubular packer section having a longitudinal axis and an internal volume, the tubular packer section further comprising:
a packer pipe;an upper packer collar comprising an external flange on the packer pipe, the upper packer collar having a plurality of pass-through holes parallel to the longitudinal axis of the tubular packer section;a lower packer collar comprising an external flange on the packer pipe, the lower packer collar having a plurality of pass-through holes parallel to the longitudinal axis of the tubular packer section;a packer sleeve secured to the upper packer collar and the lower packer collar, the packer sleeve comprising a flexible, water-impervious material, wherein the packer sleeve has an inner surface in fluid communication with the internal volume of the tubular packer section through a hole in the packer pipe through which the packer sleeve may be inflated or deflated by the flow of fluid therethrough;wherein each packer collar pass-through hole comprises an external collar connector located external to the packer sleeve and an internal collar connector located within the packer sleeve; andat least one tube line configured to be connectable between any of the plurality internal collar connectors of the upper packer collar and any of the plurality of internal collar connectors of the lower packer collar.
