Abstract:

A method and apparatus for drill pipe conveyed logging is disclosed. In a highly deviated well borehole, the apparatus comprises a housing for surrounding a logging tool, lockable and releasable rotating standoff means along said housing, and weights along one side to rotate said housing against or relative to the low side of the deviated well bore. The apparatus further includes rotary means joining the housing to the pipe string. A male wet connector enclosed in a sealed capsule is affixed at the top end of the housing and is electrically connected to the logging tool. A cooperative female wet connector in a similar closed capsule is supported on a logging cable. The logging cable is pumped down, mechanical connection is made, separate electrical connection between the mating connectors is made, and drilling fluid is excluded by virtue of positioning the mating connectors in separate closed capsules which are filled with a selected insulating liquid. A method of operation for connection and disconnection is also disclosed.
