摘　　要：设计制作了一种国柱壳增强结构探头并用其装配成 １２元 ６０ｍ长线阵，灵敏度高，结构紧凑，能在高温高压条件下工作，性能稳定可靠。文中给出测试结果并予讨论。在油田勘探、深海考察、地震监测和地球物理研究中有广泛应用前景。对其构形尺寸稍加改进可用在超深井中工作。This paper present both a small-size sensor to possess a concentric cylinedrical metal shell reinforced structure, and a 12-elements 60 m long line array being assembled by this king of sensor,They can operate especially under high temperature as well as high pressure environment and have advantage of the good stability, reliability, high sensitivity, compactly in structure. In this Paper, the design manufacture and experiment measure resulcs are given and discussed for the two of them. This apparatuse has a wide application prospects in the field of oilfield exploitation, deep sea study, seismic activity monitority and geophysical survey. Change slight configuration size of the sensor it will apply to extra-deep wall research. That will have higher practical value.
