Abstract

Un método para reducir la presión de contacto entre superficies de apoyo de una herramienta de pozos puede incluir construir una estructura que soporta una superficie de apoyo en contacto con la otra superficie de apoyo, y reducir la presión de contacto entre las superficies de apoyo al mitigar energía de deformación en la estructura. Una herramienta de pozos puede incluir una superficie de apoyo que hace contacto con otra superficie de apoyo. Hay una transición entre contacto y ausencia de contacto entre las superficies de apoyo. Una estructura que soporta una de las superficies de apoyo puede tener una rigidez reducida, por lo cual se reduce una presión de contacto entre las superficies de apoyo en la transición. Las superficies de apoyo pueden estar formadas sobre un apoyo de empuje, un apoyo de fricción, u otro tipo de apoyo entre componentes de la herramienta de pozos.
