Single phase fluid sampling apparatus and method for use of same
摘要
An apparatus (300) for obtaining a fluid sample in a subterranean well includes a housing (302) having a sample chamber (314) defined therein. The sample chamber (314) is selectively in fluid communication with the exterior of the housing (302) and is operable to receive the fluid sample therefrom. A debris trap piston (318) is slidably disposed within the housing (302). The debris trap piston (318) includes a debris chamber (326). Responsive to the fluid sample entering the sample chamber (314), the debris trap piston (318) receives a first portion of the fluid sample in the debris chamber (326) then displaces relative to the housing (302) to expand the sample chamber (314).
