    摘要: A formation fluid evaluation system (800) interconnected within a tubular string (818) for operation in a wellbore (802) having multiple zones (806, 808, 810). The evaluation system (800) includes a set of straddle packers (820, 822) that is operable to sequentially isolate the multiple zones (806, 808, 810). A test valve (824) is disposed between the straddle packers (820, 822). A fluid unloading assembly (828) is positioned uphole of the straddle packers (820, 822). The fluid unloading assembly (828) is operable to draw fluid (834) from the isolated zone (808) into the tubular string (818) through the test valve (824) in response to the circulation of a drive fluid down the tubular string (818). A formation evaluation instrument (836) is disposed within the tubular string (818) and determines a characteristic of the fluid (834) received from the isolated zone (808).
