Pressure Transducer with Quartz Crystal and Its Application in Well Logging.

Wang Yanbo, Chen Fengying et al.  
Pressure transducer with quartz crystal is a new pressure transducer developed after the conventional strain transducer, which has the characteristics of high accuracy and high stability. QP97 quartz gauge developed by Xijie Instrument Ltd. (Pudong Shanghai) adopts this type of pressure transducer. It can be used for pressure measurement in oil/gas well, water well, geothermal well. Combined with 1 7/16 in multiparameters tool under DDL Logging System, it has been run in more than 30 wells in Zhongyuan Oilfield. The application result shows that its accuracy, stability and cost efficiency are much better than strain gauge.
