Fluid Isolating Pressure Equalization in Subterranean Well Tools |
摘要 |
A fluid isolating pressure equalization in a subterranean well. A well system includes a well tool including a chamber therein containing an electrical assembly in a dielectric fluid, and a pressure equalization apparatus including a flowpath having opposite ends. One end is connected to the chamber, and the other end is connected to a source of another fluid. The flowpath extends alternately upward and downward between the opposite ends. A pressure equalization apparatus for use with a well tool in a subterranean well includes multiple spiral wraps of a tube. A flowpath in the tube extends in opposite directions in respective successive wraps of the tube.
