Abstract

En kabel (10) for bruk ved utplassering av hjelpeutstyr i et borehull som beskrevet, omfattende en ledende kjerne (12) som er isolert fra minst ett lag (18, 20) armeringstråder ved hjelp av et isolasjonslag (16). For å styre migrasjonen av brønnfluider gjennom trykkreguleringsutstyret, er hulrommene (24) mellom armeringstrådene (22) fylt med et elastisk mate- ¿ riale for å forhindre at brønnfluider siver inn i hulrommene (24) mellom armeringstrådene og dermed skader kabelen (10). Det elastiske materiale binder seg sterkt til armeringstråde- ne (22), og hindrer armeringstrådene i å skille seg, selv et- ter gjentatt bruk eller tap av stramhet. Armeringen fylt med elastisk materiale gir således tilfredsstillende mekanisk styrke for å bære relativt store belastninger. Det elastiske materiale gir også kabelen en glatt ytterflate.A cable (10) for use in placing auxiliary equipment in a borehole as described, comprising a conductive core (12) isolated from at least one layer (18, 20) of reinforcing wires by means of an insulation layer (16). To control the migration of well fluids through the pressure control equipment, the cavities (24) between the reinforcing wires (22) are filled with an elastic material to prevent well fluids from seeping into the cavities (24) between the reinforcing wires and thus damaging the cable (10). The elastic material binds strongly to the reinforcing threads (22) and prevents the reinforcing threads from separating, even after repeated use or loss of tightness. The reinforcement filled with elastic material thus provides satisfactory mechanical strength to carry relatively large loads. The elastic material also gives the cable a smooth outer surface.
