摘要: 用理论计算和室内实验方法研究了声波采油中换能器位置与透射系数的关系。解释了现有文献中测量结果不一致的现象。同时说明了超声波向油层的辐射能量少、因而辐射效率不高的原因。根据生产现场不同需要,为换能器的设计提供了一定的理论依据.

关键词: 声波采油, 换能器位置, 透射系数, 频率响应, 辐射能量

Abstract: The relation of transmitting coefficient with transducer's position was discussed with some theoretical algorithms and experiments.The disagreement of various experimental results in present references and the causes of lower radiation efficiency of ultrasonic energy were explained.The theoretical foundations for designing transducer under different production conditions may be provided.

Key words: ultrasonic oil exploitation, transducer’s position, transmitting coefficient, frequency response, radiation energy
