摘　　要：随着地震采集的深入发展，地震勘探已经越来越多的涉及到城区、油区、管道等障碍物繁多的地区。由于大量障碍物的存在，很容易造成地震资料空白，从而为后续的处理和解释带来困难。从造成地震资料空白的因素出发，提出通过检波点多次偏移归位、自动偏点优化设计及灵活的施工最小安全距离确定等综合技术以减少资料空白区，提高数据的完整性。事实证明，这对于复杂地区的地震勘探施工有着重要的意义。With the deepening development of seismic acquisition, seismic exploration is more and more related to the urban area, oil area, pipeline and other areas with many kinds of obstacles. Due to the large number of the existent obstacles, it is easy to cause blank seismic data, which brings the difficulties of follow up processing and interpretation. A set of comprehensive technology for reducing blank seismic data and improving data integrity is proposed by receiver point multi-migration homing, auto offset points optimization and flexible calibration of minimum operation safe distance. It is proven to have a very important significance for seis- mic exploration in complex areas.
