Abstract
Disclosed is a liner top test tool with a scraper cartridge and seal back-up rings for testing casing integrity in a wellbore. The seal back-up rings are comprised of first and second ring elements that are biased apart by compression springs. The first ring element has a boss that inserts into a bore of the second ring element, blocking debris from flowing into the interior of the seal back-up ring.
