福山凹陷博厚-皇桐地区三维地震采集参数设计与论证
|
摘要
地震勘探设计与评价(SED)是近些年野外采集领域兴起的新技术,该技术基于地震采集模拟软件,充分利用探区已有的地质成果和地球物理参数,建立地震地质模型进行模拟采集,并结合相关的理论技术辅助野外地震施工设计,形成了从基本参数的设计论证,观测系统的属性分析,到地震模型的模拟采集等一套完整的地震数据采集论证体系。在福山凹陷博厚-皇桐地区三维地震采集施工设计中充分运用SED技术进行基本参数的设计与论证,优选了12线3炮细分面元观测系统,属性分析表明,该观测系统在保持主测线方向覆盖优势的同时,实现了较宽方位角激发接收,有利于压制侧面和散射干扰及提高静校正耦合效果,近、中、远炮检距分布均匀,有利于速度分析。以合理的覆盖次数和相对较少的设计炮数,节约了勘探成本,实现了地震采集质量控制。
Seismic Evaluation and Design(SED)is a new technology being used in field data acquisition in recent years.This technique bases itself on seismic survey modeling software,employs geological information and geophysical parameters in surveying area to build seismic-geology model,simulate the field surveying,offers aid in making field plan according to correlative theory and technology.An integrated system for seismic evaluation and design has formed,which includes basic parameters designing,field lay out analyzing,seismic-geological modeling and so on.SED technique is fully used to design and demonstrate the basic parameters in making field survey plan of Bohou-Huangtong 3D seismic survey,Fushan Sag.A bin-divisible lay out with 12 lines and 3 shots is selected because of advantage in several aspects.This kind of lay out achieves the better azimuth relationship between shots and receivers while keeps predominance along the inline direction,that is helpful to decrease the lateral and dispersion waves,improve the coupling of static time correction.In this lay out,the offset is distributed equably for near,medium and far field,which is propitious to velocity analysis.As the result,the designed lay out achieved the quality control in data acquisition while saved cost with reasonable fold and shot number.
