现阶段针对三维地震采集工程,详细的浅层地质地震条件调查尤为重要,其调查程度直接关系到地震资料的品质,本文以全球情报系统(GIS)信息资源为基础、以global_mapper14软件为平台、结合探区卫星图片、浅层地质信息、详细划分探区浅层地震条件区域,以便在施工初期就针对不同的表层分区情况,采取不同的表层调查方法,使表层调查细化,在细化的区内进行行之有效的井中微测井调查,详尽的表层结构与地震试验结合,为区域内激发井深的优化提供准确的参考依据。
At this stage, it is very important to investigate the seismic conditions of shallow geologic area for the collection of 3D seismic data. The investigation level is directly related to the quality of seismic data. Based on the global information system (GIS) information resource and the global_mapper14 software platform, A satellite image of the exploration area and shallow geological information are used to divide the shallow seismic condition area of the exploration area in detail so as to adopt different surface investigation methods for different surface layering situations in the early stage of construction to refine the surface survey. In the well-borehole micro-logging survey, the detailed surface structure and seismic tests combined to provide an accurate reference for the optimization of the excitation well depth within the region.
