【Abstract】 Ultrasonic phased array imaging logging technology can provide technical support for accurately depicting wellbore morphology, identifying geological features such as fractures, pores, and bedding. Based on the introduction of the structure and principle of the ultrasonic phased array imaging logging system, a comparative analysis of the functions, technical characteristics, application scenarios, and application ranges of five mainstream phased array logging instruments developed by foreign petroleum instrument companies is conducted. It is shown that this logging technology can provide high-precision imaging and evaluation of the wellbore and surrounding formation in complex downhole environments. The development trend of phased array imaging logging technology is prospected, and it is pointed out that research and development efforts should be strengthened in the areas of efficient and highly sensitive transducer design, advanced data processing technology, and instrument intelligence to further improve the efficiency and safety of oil and gas exploration and development.更多还原
