As the well logging instrument is moved along the wellbore, a record of the signals generated by the sensors is made with respect to time and/or depth of the sensors within the wellbore. There are a number of different devices known in the art for moving the well logging instrument along the wellbore. The instrument may be affixed to the end of an armored electrical cable, which is unwound from w winch or similar spooling device to extend the instrument into the wellbore by the action of Earth's gravity. The instrument is withdrawn by rewinding the cable onto the winch. The well logging instrument may be moved along the wellbore by coupling it to the end of a coiled tubing, and unspooling and spooling the coiled tubing to move the instrument into and out of the wellbore. The instrument may also be coupled to the end of a threadedly coupled pipe, called a pipe “string.” The pipe string with the instrument attached to the lower end thereof is extended into the wellbore by threadedly coupling segments of pipe end to end. The pipe string is withdrawn from the wellbore by threadedly uncoupling segments of pipe.
U.S. Patent Application Publication No. 2004/0074639 filed by Runia discloses another device for moving the well logging instrument along the wellbore. The system comprises a tubular conduit or pipe extending from the Earth's surface into the wellbore containing a body of wellbore fluid. A well logging instrument string is included that is capable of passing from a position within the conduit to a position outside the conduit at a lower end part thereof and capable of being suspended by the conduit in said position outside the conduit. In some embodiments the well logging instrument may include a pressure pulse device arranged within the conduit in a manner that the pressure pulse device is in data communication with the logging tool. The pressure pulse device is capable of generating pressure pulses in the body of wellbore fluid, the pressure pulses representing data communicated by the logging tool string to the pressure pulse device during logging of Earth formation by the logging tool string.
In using the device disclosed in the Runia '639 publication it has been found desirable to be able to control the speed of movement of the well logging instrument

 As the well log instrument is moved along the wellbore, a criminal record of the signals generated by the detector is made with respect to time and/or depth of the sensors within the wellbore. There are a number of unlike devices known in the art for move the well logging instrument along the wellbore. The legal document may be affixed to the goal of an armored electrical cable, which is unwound from w winch or similar spooling device to extend the musical instrument into the wellbore by the action of Earth's gravity. The instrument is withdrawn by rewinding the cable onto the winch. The well logging instrument may be moved along the wellbore by coupling it to the end of a coiled tubing, and unspooling and spooling the coiled tubing to move the instrument into and out of the wellbore. The legal document may also be coupled to the conclusion of a threadedly conjugate organ pipe, called a pipe “ string. ” The pipe string with the instrument attached to the lower goal thereof is extended into the wellbore by threadedly coupling segments of pipe end to end. The organ pipe string is withdrawn from the wellbore by threadedly uncoupling segments of pipe.

The system comprises a tubular conduit or organ pipe extending from the Earth's surface into the wellbore containing a body of wellbore fluid. A well logging instrument string is included that is capable of communicate from a place within the conduit to a position outside the conduit at a lower goal part thence and capable of being suspended by the conduit in said position outside the conduit. In some embodiment the well logging instrument may admit a pressure pulse device arranged within the conduit in a manner that the pressure pulse device is in data communication with the logging tool. The pressure pulse device is capable of generating press pulses in the body of wellbore fluid, the press pulses representing data communicated by the logging tool chain to the pressure pulse device during logging of Earth formation by the logging tool string.
