Dual flowline testing tool with pressure self-equalizer

摘要

Flowline pressure equalizer systems, methods and/or apparatuses for use on a downhole tool are provided. A pressure equalizer may be provided in communication with two flowlines. The pressure equalizer may use equalizing chambers and equalizing pistons to regulate pressure in one or both flowlines. Further, one or more flow routing modules may be interchangeable to further alter the flow scheme between the flowlines. Different plugs may house various flow routing configurations such that the plugs may be installed and/or removed in the tool string automatically or by a user.
