摘要： An apparatus for evaluating an earth formation intersected by a wellbore may include a logging tool conveyed into the wellbore through a drilling tubular, a speed control device associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the speed control device varies an annular flow space between the speed control device and a surface adjacent to control speed. The flow space may be varied using a annular member that flexes between a nominal diameter and a second larger diameter.

摘要： A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein.

摘要： Disclosed herein is a reinforcing system for a shaped charge assembly for use in a perforating gun. The shaped charge assembly includes a shaped charge combined with a longitudinal reinforcing system extending along a portion of a perforating gun barrel. The reinforcing system comprises a spine with a recess formed to receive the shaped charge of a perforating gun. The reinforcing system further comprises a compression zone coaxially disposed around a portion of the shaped charge. The compression zone is formed between a bushing and a retaining shell that also coaxially circumscribe a portion of the shaped charge and on one of their respective ends connect to the spine.

摘要： A shaped charge for generating a large hole in material such as well casing downhole in a wellbore. A shaped charge liner is oriented about a longitudinal axis, and a disk is positioned at the liner apex. When an explosive material is initiated the liner collapses into a perforating jet. The disk alters the jet formation process and changes the shape and location of a bulge within the perforating jet. Consequently, the shape of the perforating jet retains a larger diameter for generating a larger hole in the material to be perforated or for controlling the penetration depth. The disk surfaces can be flat, concave, convex or other shapes, and the disk composition can be varied to accomplish different design criteria.

摘要： A shaped charge having a charge case and liner with an outer layer and an inner layer. The liner is a generally hollow frustoconically shaped member with an open end and a closed end, where the closed end of the liner inserts into an opening in the charge case. An explosive is provided between the liner and the charge case. The inner layer of the liner includes a higher density material than material used for forming the outer layer.
