摘要: A sample module for a sampling while drilling tool includes a sample fluid flowline operatively connectable between a sample chamber and an inlet, for passing a downhole fluid. A primary piston divides the sample chamber into a sample volume and a buffer volume and includes a first face in fluid communication with the sample volume and a second face in fluid communication with the buffer volume. A secondary piston includes a first face in fluid communication with the buffer volume having buffer fluid disposed therein and a second face.

摘要: A connector connects auxiliary flow lines—and, in some configurations, electrical lines—that extend through and terminate at or near opposing ends of two respective components of a downhole tool string. The connector comprises a body assembly for fluidly-connecting the auxiliary flow lines and electrically-connecting the electrical lines of the respective two components, and an assembly for adjusting the length of the body assembly. In particular embodiments, the two components are discrete modules of a unitary tool, or alternatively, are distinct tools. Additionally, the connector may include a mechanism for closing the auxiliary flow lines of one or both components upon disconnection of the fluid connection between the two components.
