Abstract

A well tool can include inner and outer seals interposed between components of the well tool, and a circumferential spacer which prevents contact between the inner seal and one of the components which displaces relative to the inner seal. A method of sealing between components of a well tool can include sealingly engaging an outer seal between the components, and disposing an inner seal between the components, including spacing the inner seal away from one of the components, whereby the inner seal sealingly contacts one of the components only after the well tool is disposed in a well. A drill bit can include inner and outer seals interposed between components of the drill bit, and a circumferential spacer which prevents contact between the inner seal and one of the components, the circumferential spacer being positioned upstream of the outer seal relative to a lubricant supply of the drill bit.
