摘要： Three-position fluid valves for use in downhole environments are disclosed. An example valve includes first, second and third ports, a chamber coupled to the second port, a first sleeve to selectively couple the first port to the chamber and the second port, a second sleeve to selectively couple the third port to the chamber and the second port, and a piston that forms at least part of the chamber and is coupled to the sleeves. The piston moves between a first position in which the piston displaces the first sleeve to couple the first port to the chamber and the second port, a second position in which neither of the first or third ports is coupled to the second port, and a third position in which the piston displaces the second sleeve to couple the third port to the chamber and the second port.

摘要： A downhole formation fluid pumping and a sampling apparatus are disclosed that may form part of a formation evaluation while drilling tool or part of a tool pipe string. The operation of the pump is optimized based upon parameters generated from formation pressure test data as well as tool system data thereby ensuring optimum performance of the pump at higher speeds and with greater dependability. New pump designs for fluid sampling apparatuses for use in MWD systems are also disclosed.
