Abstract

A modular cable unit for oilfield wireline includes multiple cable modules. The cable modules are interchangeable to achieve a modular cable unit with desired telemetry and electrical properties to suit a specific application. The cable modules can be an optical fiber module, a power cable or an opto-electrical module assembly. The cable modules that make up the modular cable unit are preferably arranged in a triad configuration defining a substantially triangular tangent periphery and are surrounded by a polymeric casing having a circular periphery. The triad configuration of the modular cable unit contributes to an improved mechanical strength. A floating-tube type optical fiber element with improved mechanical strength is also disclosed.

First claim

What is claimed is:

1. A cable module, comprising:
a primary cable package including only three primary conductor elements of substantially equal diameters, the three primary conductor elements being adjoined to form a substantially triangular tangent periphery, the primary conductor elements defining a central space between each of the primary conductor elements and interstitial spaces between the adjoining primary conductor elements;
a filler rod element disposed in the centra…
