DESIGN OF AN ULTRASONIC PHASED ARRAY TRANSDUCER FOR IMAGING BOREHOLE WALL

Han DONG  Fang-fang SHI  Chao KONG  Bi-xing ZHANG  
【摘要】:In this paper,an ultrasonic phased array transducer which is designed as a Cylindrical Linear Phased Array(CLPA)is presented for imaging borehole wall.Firstly,the parameters of CPLA transducer are studied,optimized,and determined based on the numerical simulation of propagation and attenuation of the radiated acoustic wave of the transducer in the borehole medium.Then a CPLA transducer is designed and fabricated by high-temperature and high-pressure resistance wafer material and structure.Finally,the experiment study is conducted in a casing borehole by the CPLA transducer with the help of a phased array electrical system.The imaging of the casing borehole wall can reflect the basic information of the casing borehole wall in the experiment,which means that the CLPA transducer has good imaging capacity with high resolution.
