地震数据体是由物探方法得到的能够反映地下信息的一组数字信息,通过地震解释工作站,地质工作者便可描述出地下情况,如何尽可能的充分利用所取得的地震数据更准确的对地下情况进行描述是解释工作者所需掌握的技能。本文以廊固凹陷河西务构造带为例,运用地震属性分析技术,波阻抗反演技术对沙一段,沙二段砂体的展布及厚度进行认识和总结,为该区的有利区带预测打下基础。
Earthquake data volume is a group of digital information obtained by geophysical methods that can reflect the underground information. Through the seismic interpretation workstation, geologists can describe the underground conditions and how to make the best use of the acquired seismic data as much as possible to the underground Description of the situation is to explain the skills required by the worker. Taking Hexiwu tectonic belt in Langgu depression as an example, this paper uses seismic attribute analysis and wave impedance inversion techniques to understand and summarize the distribution and thickness of sand bodies in Sha-1 and Sha-2 Member, lay the foundation.
