Abstract

An improved ram inner seal assembly used in ram-type BOPs is disclosed. The disclosed invention provides an inner guide seal assembly that comprises a specially shaped guide body and a separate sealing element. When the ram-type BOP is closed, two opposing rams move toward one another, and the inner guide seal assembly guides a wireline (or other tubular) toward the center of the vertical bore through the BOP. The inner guide seal assembly's proximity to the ram body's centerline axis helps ensure that a positive seal is formed and that no damage occurs to the device in the central bore of the BOP. The separate, specially-shaped sealing element can be easily inserted into and removed from the guide body of the inner guide seal assembly for easy replacement.
