摘要
通过对检波器耦合理论研究 ,根据沙漠区的地震环境和地表结构 ,设计出了不同类型的检波器耦合装置 ,增加了检波器与沙漠地表的耦合性能。从野外进行对比试验资料分析 ,在沙漠区地震检波器耦合具有高分辨率、抗干扰、耦合性好、适应领域广等特性 ,接收的地震信号能量、优势信噪比频带宽度和信号保真度等方面均有明显提高 ,将从根本上解决沙漠区高分辨率和深层地震勘探的难题。
Through a study of geophone coupling theory, accor di ng to the seismic environment of the desert area, different shapes of geophones were designed to weaken the noise produced by sound wave, wind wave, fluid mediu m, electromagnetism etc; according to the surface structure of desert area, diff erent types of tailcone were designed to enhance the coupling between the geoph one and the desert surface. The preliminary analysis of testing data in the fiel d shows that the new type of geophone in the desert area is of high resolution, strong capability in anti interference, good coupling,and wide adaptation for different fields. The results show that compared with the conventional coupling model, this method is capable of obtaining seismic reflection signal's that are better in energy, frequency bandwidth and fidelity.
