三维地震采集施工模板优化布设方法的探讨

Discussion on the method of optimization layout on 3D seismic acquisition operation template

随着以高密度为核心的“两宽一高”三维地震勘探技术大规模应用,野外采集施工效率及成本问题日益突出。针对具体项目而言,提高施工效率,优化资源配备,降低勘探成本是物探施工队伍需要重点关注的问题。通过引入不同施工模板布设方式的对比分析、建立模版炮道峰值计算函数模型等技术手段,依据精细量化分析数据化成果,探索出综合实现三维观测系统属性约束下的采集施工组织优化布设方案,为指导物探队合理配置采集资源、优化组织排列布设施工、科学拟定项目采集计划等方面提供了借鉴。

With the development of"Two-wide-One-high"seismic exploration technology featured by high density seismic acquisition,the problem of operation efficiency and cost of field seismic acquisition are becoming more and more serious.For specific projects,optimizing resource arrangement,reducing acquisition cost and improving operation efficiency are the key issues for seismic crews.In this paper,we proposed the ratio of shots and receivers in operation template with different layout mode and calculation function model of shots and receivers peak value in template.On the basis of precise quantitative analysis numerical results,optimization schemes of seismic acquisition operation and organization under the attribute constraint of 3D geometry are explored.It provides theoretical and technical support for guiding the reasonable arrangement of acquisition resources,optimizing array arrangement and array layout,and drawing up the project acquisition plan scientifically.
