Abstract
Well tools are run into a well, usually a deviated well, using a composite wireline cable made up of a bundle of parallel slidable composite rods and electrical or optical conductors covered with a flexible protective sheath. The cable is stored on a spool and from there it is run into and retrieved from the well.
Claims9
A high strength composite spoolable cable for running a well tool in and out of a wellbore and particularly running tools in highly deviated wellbores, the cable comprising:
- a plurality of parallel elongate composite rods arranged to slide relative to each other in a bundle;
- an outer flexible protective sheath for covering said plurality of rods and holding said rods together in said bundle;
- and
- energy conductor means arranged within said outer protective sheath.
A high strength composite spoolable cable for running a well tool in and out of a wellbore and particularly running tools in highly deviated wellbores, the cable comprising:
- a plurality of parallel and slidable elongate composite rods arranged in a bundle wherein the rods may slide relatively to each other and wherein each of said rods is formed of generally axially oriented high strength fibers fixed in a binder;
- an outer flexible protective sheath for covering said plurality of rods and holding said rods together in said bundle;
- and
- energy conductor means arranged within said outer protective sheath.
In a well system having a wellbore extending into an earth formation wherein the wellbore has at least one deviated portion relative to the remainder of the wellbore, a well tool inserted into said wellbore, and a composite cable connected to said well tool for inserting and removing the same, wherein the composite cable comprises:
- a plurality of parallel and slidable elongate composite rods arranged in a bundle wherein the rods may slide relatively to each other and wherein each of said rods is formed of generally axially oriented high strength fibers fixed in a binder;
- an outer flexible protective sheath for covering said plurality of rods and holding said rods together in said bundle;
- and
- electrical conductor means arranged within said outer protective sheath.
