Abstract
A centralizer for a downhole probe disposed within an eccentric pipe, the centralizer having an elongated, primary tubular member with three or more elongated centralizer strip assemblies extending along the primary tubular member. Each strip assembly has inner and outer portions opposing one another on the wall of the primary tubular member and spaced apart from one another about the circumference of the wall. The inner portions of the strip assemblies engage the outer diameter of a probe and are all sized and shaped to have the same inner radial length. The outer portions of the strip assemblies have at least two different outer radial lengths, where one of the outer portions has an outer radial length longer than any other outer radial portions. The outer radial lengths are selected so that the sonde can be coaxially positioned within the eccentric pipe relative to the outer diameter of eccentric pipe.
