江陵凹陷复杂地表三维地震资料采集方法研究

Method for 3D Seismic Data Acquisition in Complex Surface Area of Jiangling Depression

复杂地表条件对地震资料的品质产生严重的影响。针对江陵凹陷万城构造复杂地表条件,通过试验,提出精确表层结构的调查、水体对地震信号干扰的模型正演分析以及震源类型的合理选择等改善地震资料品质因素的方法。应用结果表明,在复杂地表地质条件下,用该方法提高地震资料质量是行之有效的。

The condition of complex surface area has important effect on the quality of seismic data.Aim at the condition of the complex surface area in Wangchang Structure in Jiangling depression,this paper puts forward the precision survey of surfer layer,the model forward of water influence for seismic signal,and the propriety choice of hypocenter style to improve the quality of seismic data.The applied result shows that those methods are effective to get high quality seismic data in the complex surface area.
