摘　　要：多极子阵列声波成像测井已经成为测井中主要方法之一,在地层评价与油气田开发中有重要作用。在已有理论与数值模拟的基础上,经过近十年的技术攻关,我们已经在多极阵列声波成像仪器制造、测试与数值处理等主要关键技术方面都取得了长足的进展,具体包括高温正交偶极子发射换能、高温低频单极子换能器、声系测试、多极子阵列声波测井高温电路及仪器集成、资料处理及解释等主要方面。所研制的仪器及资料处理方法,经过与国外同类仪器的测井结果进行了对比分析,验证了所研发的仪器的可靠性和处理方法的正确性,这些关键技术为我国声学测井仪器装备技术研发和快速发展打下了基础,提供了技术支撑。Multipole sonic logging is a principal method in borehole logging and plays an important role in formation evaluation and oil field exploration and development. Based on theory and simulation results, we had taken much progress in some key technologies on manufacture, test and related data processing method and software of multipole sonic logging tool through almost ten year＇s study and hard working. These key technologies include transducers of conventional transmitter and receiver for crossdipole and low frequency monopole transmitter and their test in laboratory and water tank, circuit and assembly of the downhole tool and related data processing and interpretation. Comparison with the imported instrument and processing software, the accuracy and reliability of our tool and software were validated. These lay a solid foundation for the research and development of sonic logging instrument.
