| Multipole..sonic logging is one principal method in borehole logging and play an important role in formation evaluation and oil field exploration and development. Based on theory and simulation results gotten in advance, 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 will lay a solid foundation for the research and development of our country’s sonic logging instrument. |
