High temperature piezoelectric ceramic ultrasonic transducers oil

Ultrasonic acting on the object, the object can generate vibration, ultrasonic vibration amplitude and intensity depending on the frequency of the sound source of power, these two indicators can precisely control in modern electric acoustics. 

     Therefore, ultrasound has been widely used in modern industry. Especially in the ultrasonic cleaning, the application more widely. 

     In ultrasonic cleaning, the change in frequency and intensity of ultrasound to determine the object to be cleaned substrate impact strength. The higher the frequency, the higher the surface of the substrate cleaning intensity. The lower the frequency, the greater the impact on the depth of the substrate. 

     Ultrasonic extraction technology is the use of high-power transmitter ultrasonic transducers send ultrasonic enable formation medium for intense mechanical vibration, ultrasonic propagation time role in the formation is relatively far away, it can undermine the cohesion of blockage between the particles and the reservoir rock, so that when the spread is relatively far from the action, the near wellbore porosity or pore throats attached blockage loose, fall off, and with the subsequent drainage discharge formation, play to clear the drain channel, enhance the role of production. 

     Oil before ultrasonic transducer only relatively poor high temperature performance and high power, in the wells at 100 ° C due to their energy consumption will be high temperature, the leakage current of the transducer is large, resulting in low efficiency of the ultrasonic extraction. The reason is that the material properties of the piezoelectric ceramic caused by the high electric conductivity. 

     New piezoelectric ceramic material which retains the characteristics of the piezoelectric ceramic power, but also has high piezoelectric constant, high electromechanical conversion efficiency, low electrical conductivity, with the production of the piezoelectric ceramic ultrasonic transducer in oil 150 degrees Celsius deep flooding in ultrasound, ultrasonic extraction is difficult to solve the deep problems. 

     Currently produced by the piezoelectric ceramic ultrasonic transducers oil in Shengli Oilfield plant has more than oil wells, the user response is good.
