Hydraulic Centralizer

Definition - What does Hydraulic Centralizer mean?

Hydraulic Centralizer is a downhole tool that applies hydraulic force for energizing the centralizer bows or arms in thru tubing applications. The thru tubing applications need a tool string for centralizing within the liner or casing below the tubing. They are designed for making the work strings of their parts to be centralized in casing or tubing for numerous applications. In the original conditions, strings are compressed and are easy to be run into the well. These strings expand only when the pressure differential is accomplished across the tool.

Petropedia explains Hydraulic Centralizer

Hydraulic Centralizer is engaged after raising the hydraulic pressure for energizing the bows or arms. It is connected with the standard coiled tubing with the help of connectors. It has hydraulic, simple structure, convenient operations and is used for easy recycling or running. The Hydraulic Centralizer is used in expanded conditions and therefore it helps in preventing the bow spring damage. The centralizers are wide with variety of specifications. A large expansion is required for thru tubing applications which is not generally present within the operating range of the conventional models of the centralizers.
