摘要： A downhole tool includes a tool body having an outer surface portion and an inner surface portion and a recess formed in one of the outer surface portion and inner surface portion. At least one removable electronic component access member is detachably mounted to the tool body. The removable electronic component access member provides access to electronic components housed in the recess. A metallic seal is provided on at least one of the tool body and the removable electronic component access member. The metallic seal prevents fluid ingress into the recess through the at least one removable electronic component access member.

摘要： A downhole tool includes a tool body having an in inner surface portion and an outer surface portion. The outer surface portion includes a recess having a peripheral wall and an inner surface. A multi-chip module (MCM) housing is defined in the recess. The MCM housing includes one or more fortifying members that support axial and radial loading of the downhole tool and include one or more electronics receiving zones.
