摘要： The invention addresses protecting the free ends of communication lines from debris during downhole wet-mate connection in a wellbore, with protection of the lines upon disconnection as well. A reciprocating debris exclusion device is provided for use with upper and lower tools to be connected. The lower tool has a reciprocating cover member mounted for sliding engagement with the housing of the lower tool, the cover member shielding the free end of a communication line. An upper tool has a bladder-type cover member attached to the upper tool and protecting the free end of a communication line. The reciprocating cover member is moveable between a closed and an open position and is moved in response to contact with the upper tool. The bladder cover is movable between closed and open positions and is moved to the open position by contact with the reciprocating cover member of the lower tool.

摘要： The invention addresses ways to protect the free ends of communication lines from debris during downhole connection. A lower assembly, positioned downhole, has a lower connector with a free end of a communication line. An upper assembly is moved downhole and has an upper connector. A reciprocating member with attached protective cover is mounted for movement on the lower assembly. A second reciprocating member with attached protective cover is mounted for reciprocating movement on the upper assembly. The free ends are connected as the upper and lower assemblies are moved toward one another. Upon disconnection, the upper and lower connectors are moved apart and the reciprocating members return to their initial positions, again protecting the free ends of the communication lines. The covers are preferably biased towards a closed position and return to a closed state upon disconnection.
