    摘要: A connector connects auxiliary flow lines and 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. 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 compartments upon disconnection of the fluid connection between the two components.

    摘要: A modular tool for use in subterranean formations includes a first module, a second module and one or more connectors for connecting the first and second modules. In particular, the first module includes a first collar that at least partially defines an exterior of the tool and that includes a first engagement mechanism at a first end of the collar and a second engagement mechanism at a second end of the collar. The first module also includes a fluid passageway for passing drilling fluid therethrough. The second module has a similar configuration as includes similar architecture. The one or more connectors facilitate the connection of at least one flowline fluidly connected to an exterior of the tool, and an electrical pathway for transmitting power and/or data between the modules.

    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. An agitator is disposed in the sample volume for agitating the sample fluid. A secondary piston includes a first face in fluid communication with the buffer volume having buffer fluid disposed therein and a second face.
