Power systems for wireline well service using wired pipe string

Abstract

A wellbore instrument system includes a pipe string extending from earth's surface to a selected depth in a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal channel. A power sub including an electric power source is coupled proximate a lower end of the pipe string. At least one electrically powered wireline configurable wellbore instrument is coupled to the power source in the sub.

         23 . A wellbore instrument system, comprising:
 a pipe string extending from earth's surface to a selected depth in a wellbore, the pipe string comprising wired drill pipe communicatively coupled at each joint;   an adapter sub coupled to the pipe string proximate a lower end of the pipe string, the adapter sub including a source of electric power therein;   at least one wireline configurable wellbore instrument coupled to the adapter sub on an opposite side of the pipe string;   wherein the power source comprises a piezoelectric crystal configured to convert at least one of pipe vibrations and fluid pressure variations into electric power.   
     
     
         24 . The system of  claim 23  wherein the pipe string comprises pipe segments threadedly coupled end to end, each pipe segment including at least one signal communication device in a longitudinal end thereof for coupling signals to a device coupled to the pipe segment. 
     
     
         25 . The system of  claim 24  further comprising a telemetry tool configured to receive signals from the at least one wireline configurable instrument and to reformat the signals for transmission over a communication channel in the pipe string. 
     
     
         26 . The system of  claim 23  wherein the adapter sub is coupled to a power converter module converting output of the power source into suitable form to operate the at least one wireline configurable instrument. 
     
     
         27 . A method for well logging, comprising:
 moving at least one wireline configurable wellbore instrument along a wellbore at one end of a segmented pipe string, the pipe string including having a communication channel associated therewith;   providing electrical power proximate a downhole end of the segmented pipe string to operate the wellbore instrument;   communicating measurements from at least one sensor in the instrument to the signal communication channel;   detecting the communicated measurements proximate a surface end of the communication channel; and   wherein the providing electrical power comprises converting at least one of vibration in the pipe string and fluid pressure variation into stress on a piezoelectric crystal.   
     
     
         28 . The method of  claim 27 , further comprising storing at least a portion of the measurements in a data storage device proximate the well logging instrument.
