摘要

垂直地震剖面(VSP)勘探方法在我国使用已有近20年的历史,由于勘探设备的限制和对其方法应用认识不足,还是从勘探设备及应用方法发展的缓慢,都大大滞后于地面勘探设备的发展。近几年来,随着电子工业的飞速发展,井下勘探有了很大的进步,勘探方法也呈现多样化,VSP仪器从最初笨重的单级模拟传输逐步发展到今天的多级数字传输,VSP方法从最初简单的求速度到今天的二维以及三维高分辨率成像勘探。文章对近年来VSP采集技术进行了总结分析,并在此基础上提出了多级数字VSP采集仪器设计思路。
Although application of the exploration method of vertical seismic profiling in our country has near 20 years,because of the limit of explore equipment and insufficient understanding for method and application,its equipment development and application methods are very slow,lag behind surface equipment.In recent years,along with the swift development of electronics industry,the mine shaft exploration has very progress,the exploration method has also diversification,the VSP instrument is gradually developed from the unwieldy single stage analog transmission at first to today's multistage digital transmission(to reach as high as 32 levels of 4ms),VSP method from at first simple asking speed to today 2D as well as 3D resolution image formation exploration.The paper summarizes and analyzes VSP acquisition technology in recent years,and proposes design ideas of a multi-level digital VSP acquisition instrument.
