APPLICATION OF UNCONVENTIONAL WELL LOGGING TECHNIQUE IN PRODUCTION LOGGING OF HORIZONTAL WELL

Due to the variation of borehole geometric position and flow regimes of horizontal well, the conventional production logging tools can not adapt to the horizontal well quite well. However, many unconventional logging methods present their advantages. This paper introduces two of them that are used success fully in the horizontal wells abroad:borehole televiewer and ultrasonic logging technique. This paper finally concludes:conducting combination production logging by means of both conventional and unconventional logging tools, and then conducting comprehensive interpretation to the logging results will be a great help to the analysis of production performance of the horizontal well.
