a resistivity log plot showing the different investigation results based on depth of fluid invasion.

n: The connection between the wireline logging cable and the bridle. The torpedo consists of an outer mechanical connection enclosing electrical connections between the conductors.


the connection joining the electric line logging cable and the electrical bridle at the reel.

n: the turning force that is applied to a shaft or other rotary mechanism to cause it to rotate or tend to do so. Torque is measured in foot-pounds, joules, newtonmetres, and so forth.

resistance to rotation of a string. The turning force applied to the string to cause it to rotate.

n: a hydraulic device connected between an engine and a mechanical load such as a compound. Torque converters are characterized by an ability to increase output torque as the load causes a reduction in speed. Torque converters are used on mechanical rigs that have compounds.

n: It be setted between the engine and drive mechanism,which can increase the torque when velocity decline caused by loading increasing.

n: an instrument that measures the amount of torque (turning or twisting action) applied to the drill or casing string. The amount of torque applied to the string is important when joints are being made up.

n: The gauge that be used to measure the torque.

n: an instrument that measures and makes a record of the amount of torque (turning or twisting action) applied to the drill or casing string.

n: The gauge that can measure and recorder the torque.

n: on a portable top-drive unit, the steel rail that is mounted in the derrick and to which the top drive is attached. The top drive moves up or down on the track and, because it is firmly joined to the track, cannot turn as its drive shaft rotates the drill stem. Compare guide rails, torque tube. See also top drive.

n: The tool that fixed torque indicator ,which can screw on and off the nut ,bolt and pipe.

n: a large cylindrical tube mounted in the derrick to which a top drive is attached and on which it can move up and down. Like guide rails, a torque tube prevents the top drive from turning when it is connected to the drill stem and is rotating it. Compare guide rails. See also top drive.

n: twisting deformation of a solid body about an axis in which lines that were initially parallel to the axis become helices. Torsion is produced when part of the pipe turns or twists in one direction while the other part remains stationary or twists in the other direction.
