中文摘要：
为地质的调查的更好好的记载技术着急地被需要识别并且评估复杂水库。我们与相应电路和身体描述 3D 传输器车站的一种新类型。他们能在很好记载的声学的思考的一种有希望的新技术被使用，那展示更好方位角的察觉能力，以及更好的调查深度。传输器车站由能由循环地在不同层次使各种各样的联合激动在 3D 空间的任何要求的方位角散发声学的精力的三水平的 subarrays 组成。我们测试了声学的传输器驻扎的 3D 并且与声学的传输器第一次驻扎的 3D 获得了实验室择向性大小。结果证明在水平飞机的 3-dB 横梁宽度从 59 敤瑢吗？
英文摘要：
Better well logging techniques for geologic investigations are urgently needed to identify and evaluate complex reservoirs.We describe a new type of 3D transmitter station with corresponding circuits and bodies.They can be used in a promising new technique of acoustic reflection well logging,that features better azimuthal detection capabilities,as well as better investigation depth.The transmitter stations consist of three-level subarrays that can radiate acoustic energy in any required azimuth of 3D space by circularly exciting various combinations at different levels.We tested the 3D acoustic transmitter stations and obtained laboratory directivity measurements with the3 D acoustic transmitter stations for the first time.The results show that the 3-d B beam width in the horizontal plane ranges from 59° to 67° as a result of phase-delayed excitation.The main beam is steered in the vertical plane at a deflection angle that ranges from 0° to 16° when the delay time of the excitation pulse between each pair of adjacent arc arrays is gradually adjusted.The 3-d B beam width is equal to 11°,whereas the deflection angle in the vertical plane is equal to 14°.Each of the four third-level subarrays in the same circumferential direction display consistent horizontal and vertical directivities,thus satisfying the requirements of azimuthal acoustic reflection logging.
