Downhole Pressure Compensator

摘要

The techniques herein relate to a pressure compensation system. The system includes a downhole tool and one or more pressure compensators positionable in the downhole tool. Each pressure compensator includes a first compensating fluid section having a first compensating fluid, at least one second compensating fluid section having a second compensating fluid, and a convoluted membrane between the first and second fluids in the first and second compensating fluid sections, respectively. The first or second compensating fluid sections, or both, may include a porous disk positioned at a hole in the fluid section. The pressure compensator may also include a switch configured to indicate a fluid condition in the pressure compensator and a relief valve configured to release fluid from the pressure compensator.
