Abstract

Раскрыты высокопрочные скважинные электрические кабели, которые образованы из множества защитных упрочняющих элементов. Защитные упрочняющие элементы образованы из нескольких жил из скрученных проволок, которые могут быть закрыты оболочкой из полимерного материала. Защитные упрочняющие элементы могут быть использованы в качестве центрального защитного упрочняющего элемента или даже уложены в виде слоя вокруг центрального, расположенного в аксиальном направлении компонента или защитного упрочняющего элемента для образования слоя из защитных упрочняющих элементов. Кабели по изобретению могут иметь любую реализуемую на практике конструкцию, включая одножильные каротажные кабели, коаксиальные кабели, кабели четверочной скрутки, кабели семерочной скрутки, кабели в виде талевого каната, многопроводные кабели и т.д., и имеют повышенную коррозионную стойкость, уравновешивание крутящих моментов и могут также способствовать предотвращению или минимизации опасной миграции газа из скважины к поверхности.
