摘要： An apparatus and method for characterizing a subsurface formation is provided. The apparatus includes a tool body, a probe assembly carried by the tool body for sealing off a region of the borehole wall, an actuator for moving the probe assembly between a retracted position for conveyance of the tool body and a deployed position for sealing off a region of the borehole wall and a perforator extending through the probe assembly for penetrating a portion of the sealed-off region of the borehole wall. The tool may be provided with first and second drilling shafts with bits for penetrating various surfaces. The method involves sealing off a region of a wall of an open borehole penetrating the formation, creating a perforation through a portion of the sealed-off region of the borehole wall and testing the formation.

摘要： A flow control valve includes a body having a fluid passageway therethrough and first and second openings each adapted for receiving or discharging fluid from the passageway. A piston is slidably disposed in the passageway between the first and second openings of the body. The piston has a conduit portion that defines a bore therethrough for conducting fluid through a portion of the passageway. The bore has a reduced flow area. A plug is carried within the body and is equipped with one or more annular seals for sealably engaging the reduced flow area of piston bore so as to close the bore upon translatory movement of the piston, the plug, or a combination thereof. The flow control valve has particular application in downhole tools for communicating fluid into, out of, or through the downhole tool when disposed in a subsurface borehole.

The probe assembly includes a probe body extendable from a downhole tool, and a packer carried by the probe body and having a distal surface adapted for sealingly engaging the wellbore. The packer has an outer and inner periphery, with the inner periphery being defined by a bore through the packer. The packer is further equipped with channel(s) formed in the distal surface and arranged to define an annular cleanup intake intermediate the inner and outer peripheries. The passageway(s) extend(s) through the packer for conducting virgin fluid and/or contaminated fluid between the channel(s).
