摘要
通过对比分析不同检波器及接收方式的地震资料,为地震勘探中检波器的选型与应用提供依据。研究方法包括对模拟检波器与数字检波器、无线节点仪器与有线检波器、不同频率检波器等多种类型及接收方式的地震资料,从信噪比、频率特征、成像效果等维度进行对比,结合江汉油田实际勘探案例展开分析。研究表明,需根据勘探区域地质条件、任务需求及信噪比、分辨率要求,针对性选择检波器类型与接收方式。
To support geophone selection and application in seismic exploration,this study compares seismic data quality across different geophone types and acquisition modes.Data from analog versus digital geophones,wireless nodes versus cabled systems,and geophones of varying frequency responses were analyzed.The comparison considered signal-to-noise ratio,frequency characteristics,and imaging quality.Case studies from Jianghan Oilfield demonstrate that optimal geophone type and acquisition mode must be selected based on geological conditions,survey objectives,and requirements for resolution and signal-to-noise ratio.
