Abstract

"CABO" Um cabo (10) para uso na prestação de serviços em um furo de sondagem conforme descrito que compreende um núcleo condutivo (13) que é isolado de pelo menos uma camada (18, 20) de arames de blindagem por uma camada isolante (16). Para controlar a migração de fluidos do poço através do equipamento de controle de pressão, os vazios (14) entre os arames de blindagem (22) são preenchidos com um material resiliente para prevenir que fluidos do poço se infiltrem no interior dos vazios (24) entre os arames de blindagem causando dano ao cabo (10). O material resiliente liga-se fortemente com os arames de blindagem"CABLE" A cable (10) for use in providing services in a borehole as described that comprises a conductive core (13) that is insulated from at least one layer (18, 20) of shielding wires by an insulating layer (16). To control fluid migration from the well through pressure control equipment, the voids (14) between the shielding wires (22) are filled with a resilient material to prevent fluids from the well from infiltrating into the voids (24) between the shielding wires causing damage to the cable (10). The resilient material bonds strongly with the shielding wires
