本文分析了海陆两栖地带地震勘探中同时使 用的速度检波器和加速度检波器存在的差异及其对 地震信号的影响;在此基础上,设计研制出了陆用 压电检波器,并对其性能特点进行了分析;通过试 验资料分析,消除了海陆两种不同机理的检波器资 料的相位差的问题,陆用压电检波器和水中压电检 波器记录信号的频带和能量达到一致,提高了地震 资料的分辨率;实现了海陆地区可以同时采用相同 机理的检波器进行地震信号的接收,解决了滩海地 区速度检波器和加速度检波器长期混用的问题。
This paper analyzes the differences of the speed geophones and acceleration geophones used in the seismic exploration of the amphibious zone and their effects on the seismic signals. On this basis, a piezoelectric geophone is designed and developed, and its performance The analysis of the experimental data has eliminated the problem of the phase difference of the geophone data with the two different mechanisms of land and sea. The bands and energies recorded by the land piezoelectric transducer and the hydroponic piezoelectric geophone coincide with each other, The resolution of seismic data; the realization of the sea and land areas can simultaneously use the same mechanism of the detector for seismic signal reception, to solve the beach sea area speed accelerometer and accelerometer mixed long-term problems.
