Abstract
An electrical cable in which composite rods and electrical conductors disposed between a flexible, elongated, membrane which can be pressurized and a flexible outer protective sheath surrounding but separate from the membrane, provide a pressure stiffened cable assembly that can be run into deviated boreholes.
Claims6
In a process in which a wireline actuated well tool is run into a wellbore by a spooled cable, the improvement which comprises utilizing as the cable an internally fluid-pressurized flexible membrane member stiffened with a plurality of parallel uni-directional composite rods spaced from each other and disposed axially on the outside of and in contact with said membrane, said pressurized membrane member being covered with an outer cylindrical flexible protective sheath separate from said membrane member, energy conductors positioned between said pressurized membrane and said protective sheath, the combination forming a stiffened cylindrical cable having high resistance to buckling.
A method for running a wireline operated well tool into a wellbore comprising the steps of:
- connecting the well tool to the end of a internally fluid-pressurized cable assembly comprised of a flexible membrane member, an outer protective sheath, and stiffening members between the membrane member and the protective sheath, and energy conductors integrally formed in the cable assembly;
- connecting the well tool to the energy conductors;
- inserting the well tool into the well;
- running the well tool down into the well by the cable;
- and
- utilizing the energy conductors to communicate with the well tool.
