可控震源高效采集技术简介及对装备的需求

High efficient vibrator acquisition technology introduction and the demand for equipment

可控震源高效采集方法对仪器装备提出了更高的需求。为了配合高效采集技术,要求采集仪器具有更大的带道能力和更高的传输速率,以及方便施工、系统稳定、操作便利等性能;震源要求故障率低、震源本身技术性能稳定、行进通过能力强;同时对采集设计、测量方法、资料处理等也提出了更高的需求。本文介绍了滑动扫描、ISS、DSSS、高保真高效的基本原理及施工方法,同时提出了这几种方法对装备的具体需求。

With the high efficiency and productivity seismic acquisition technique development, acquisition equipment is expected to meet the requirement which apply for high efficiency acquisition. The recording instrument are expected to have the following capabilities： system stable, high capacity with a large number active channels, high transmis sion data rate, convenience for operation etc. The vibrator are expected continuous running with low failure rate and working stable. High efficiency seismic acquisition is an integrated exploration technique with high requirements for acquisition design, survey methods, data processing etc. Four acquisition techniques （Slip sweep, ISS, DSSS, HFVS＋Flip Flop Sweep） are introduced in this paper and some detailed requirements are put forward
