摘要:
A technique distributes localized stress acting on a tubular. The tubular is formed with an inner layer and an outer layer that is compliant relative to the inner layer. A force distribution material is disposed between the inner layer and the outer layer to spread any concentrated loads acting against the tubular. The compliant nature of the outer layer causes it to distort against the force distribution material when acted on by a concentrated external load. The outer compliant layer and the force distribution material cooperate to isolate and protect the inner layer from displacements of the surrounding subterranean material.
