检波器耦合系统匹配技术

Match technique for geophone coupling system

地震检波器的作用已成为制约高分辨率地震数据采集的瓶颈。为了生产出高质量的检波器串，作者提出一种行之有效的检测方法。由于每个元件测试结果，其各项指标均有偏差，但这种偏差是随机分布的，而且这种偏差不一定符合要求。因此可通过软件系统对大批量元件进行优化组串，使串的某项技术指标的允差等于或小于元件单项指标的允差，从而使组成高精度由的成功概率很高。文中给出优选组串的测试方法，经实践检验是可行的。

Geophone becomes the crux in high-resolution seismic data acquisition. A desirable testing method is developed to produce quality seismic geophone strings.Every kind of element may have different specification deviations, which may berandom and not in allowance. We can use computer softwares to get the optimizedbatch elements whose allowance of a specification is equal to or lower than that ofthe corresponding specification of a single element. Consequently, we have highprobability to form precision geophone strings. The testing method for optimizationcombination recommended here is useful in practice.
