【摘要】 针对用于浅海滩涂地带的浅海四分量石油勘探之第四分量检波器——水听器进行了研究,从传感器网络模型出发,推导了水听器的传递函数,得出了外力与水听器敏感元件应力应变之间的关系,并对水听器建立了振动模型、进行了动态特性分析.设计了水听器的结构,并计算了灵敏度、确定了水听器的参数.对浅海石油水听器进行了性能和灵敏度测试.结果表明,水听器满足浅海勘探的要求.更多还原

【Abstract】 The fourth heft geophone of shallow sea 4C oil exploration-hydrophone used in the shallow sea and beach was analyzed.The transfer function of the piezoelectric sensor was ascertained with the network model.The relation between stress-strain of the hydrophone sensing element and external force was derived.Both dynamic characteristics analysis and vibration model of the hydrophone were done.The hydrophone structure was designed.The sensitivity of the hydrophone was analyzed and the parameters of the hydrophone were disserted.Performance and sensitivity test of the hydrophone show that the hydrophone meets the shallow sea exploration demand.更多还原
