摘要： A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug, may be used to set a packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may use a flapper mechanism to regulate passage of fluids through the housing, and a piston and/or flow tube may also be utilized to lock the flapper in an open or closed orientation within the housing.
