摘要： A well logging instrument deployment device includes a housing configured to be coupled to a pipe string. A carrier sub is disposed inside the housing and configured to move longitudinally inside the housing. At least one well logging instrument is coupled to the carrier sub. A latch is configured to retain the well logging instrument and carrier sub in a first longitudinal position along the housing such that the well logging instrument is disposed entirely inside the housing. The latch is configured to retain the well logging instrument and carrier in a second position such that at least a portion of the well logging instrument extends outwardly from the housing.

摘要： A downhole tool is provided that includes a grip assembly for contacting a well formation. The grip assembly includes a gripper body; and a centralizer that is attached to and radially expandable with respect to the gripper body and that has a geometry which is lockable by a locking device. The grip assembly also includes a force amplifier in force transmitting relation with the centralizer, wherein the force amplifier transfers a force in a first direction to a much larger force in a second direction when the centralizer is locked by the locking device.

摘要： A downhole tractor assembly that is configured for open-hole applications and of a self-aligning nature. The self-aligning nature of the assembly is effectuated through a tractor portion which is rotable about an axis of an elongated body of the assembly independent of a separate centralizing portion of the assembly. That is, the tractor portion, configured for interfacing an open-hole well wall of potentially irregular morphology, is independently rotable so as to maintain a position of substantially optimized driving friction at the interface during tractoring. Maintenance of optimized driving friction in this manner may occur irrespective of the orientation of the centralizing portion of the assembly.
