速度、加速度检波器及其获取信息的研究(英文)

摘要
本文从两种类型的地震检波器(10hz动圈式速度检波器和压电加速度检波器)及其检测介质的两种运动动参数(速度和加速度)入手,测试和对比分析了它们的频率响应函数,指出了二者的差异。又对两种检波器进行了冲击振动试验和结果对比,分析了其响应信号的特征和携带信息的能力。并于某地区在可比条件下进行了地震数据采集对比试验,对用两种检波器采集得到的单炮资料和叠加时间剖面进行了对比分析。结果表明,加速度信号更能满足当前和今后地震勘探对地震信号的高信噪比、高精度、高分辨率和大信息量的要求。
Based on the research of two geophone types (10 Hz moving-coil velocity and piezoelectric acceleration) and their velocity and acceleration parameters, frequency response functions have been determined, as well as the differences between them. Also, shock- vibration tests have been accomplished, not only to explain the two shock response signal differences, but also to analyze the response signal characteristics and its ability to carry information. In addition, seismic data acquisition experiments have been carried out under comparable conditions in the field. A contrast analysis of shot gathers and stack profiles acquired with the two geophone types is given in this paper. The results show that the acceleration signal from the acceleration geophone has a better advantage in terms of high signal-to-noise ratio, high accuracy, high resolution, and quantity of information to better meet current and future requirements for seismic exploration.
