Abstract
Pressure balanced downhole connections. A well system includes a well tool, a conduit assembly connected to the well tool, the conduit assembly including a conduit and a line positioned within the conduit, the line being connected to the well tool for operation of the well tool, and a device for equalizing pressure between an interior and an exterior of the conduit, the device being positioned downhole. A method of isolating a line in a subterranean well from well fluids in the well includes the steps of: connecting a conduit assembly to a device for equalizing pressure between an interior and an exterior of the conduit assembly, the conduit assembly including a line installed within a conduit; and positioning the conduit assembly and pressure equalizing device in the well.
Claims17
A well system, comprising:
- a first well tool connected to a first line which operates the first well tool;
- a second well tool connected to a second line which operates the second well tool;
- a conduit assembly interconnecting the first and second well tools, the conduit assembly including a conduit, and at least one of the first and second lines being positioned within the conduit;
- and
- a device which equalizes pressure between an interior and an exterior of the conduit assembly, the device being positioned downhole.
A method of isolating a line in a subterranean well from well fluids in the well, the method comprising the steps of:
- interconnecting via a conduit assembly a first well tool and a second well tool operated by respective first and second lines, the conduit assembly including at least one of the first and second lines installed within a conduit;
- connecting the conduit assembly to a device which equalizes pressure between an interior and an exterior of the conduit assembly;
- and
- positioning the conduit assembly and the pressure equalizing device in the well.
