摘要
本文通过对在水网、山地、人口稠密的城镇等复杂地区进行地震采集作业的几个实例的分析,阐述了充分发挥400系列(408UL和428XL)地震数据采集系统的效能,在复杂地表条件下灵活应用中继站、交叉站、采集链等设备构建蛇形排列,将几种不同的观测系统结合起来,采用非规则特殊观测系统等手段,来布设排列、跨越各种障碍的方法。本文介绍的方法可将复杂地区的三维测网变成一个完整的整体测网,在方便施工、确保资料品质的同时降低了成本,提高了效益。
Through some cases that the seismic acquisition job was carried out in such complex areas as water network, mountains and densely populated cities and towns, the paper expounded the method how to fully display the efficiency of 400 series (408UL and 428XL) seismic data acquisition system, flexibly using such equipments as relay station, cross station and acquisition chain to construct snake-like spread and combining several different geometry and using special irregular geometry to lay out the spread and go across various barriers. Using the method introduced in the paper can change 3-D surveying net to a complete integral surveying net in complex area, which is convenient for operation, ensuring data quality while reducing cost and improving efficiency.
