为了查明浙东地区深部构造信息,在该区域布设了一条18 km长的深地震反射剖面,并开展了深地震反射采集参数试验。本次试验采用炸药震源、法国产428XL 24位A/D转换数字地震仪和DSU1单分量数字检波器,采样间隔2 ms、道间距15 m、记录长度20.0 s,主要针对激发因素进行了较为全面的试验工作,并从实践出发对数字检波器的效能进行了分析。通过对不同激发参数原始单炮记录中目的层信噪比的比较,确定了在采用数字检波器情况下适合于该地区的最佳激发参数。 In order to ascertain the deep tectonic information in eastern Zhejiang, an 18 km long deep seismic reflection profile was laid in the area, and the deep seismic reflection acquisition parameter test was carried out. The test uses explosives source, France 428XL 24-bit A / D conversion digital seismograph and DSU1 single-component digital detector, sampling interval of 2 ms, 15 m track spacing, record length of 20.0 s, mainly for a more comprehensive incentive factors The experimental work, and from the practice of the performance of digital geophones were analyzed. By comparing the signal-to-noise ratio of the target layer in the original single shot record with different excitation parameters, the best excitation parameters suitable for the area under the condition of digital detector are determined.
