地震属性优化技术在郭家河三维地震资料解释中的应用

Application of Seismic Attribute Optimization Technology in Three-dimensional Seismic Data Interpretation of Guojiahe

由于郭家河勘探区地震地质条件复杂,勘探精度要求高,在提取多种地震属性的基础上,利用专家优选的办法选出对研究区地质构造比较敏感的属性进行解释,并在解释过程中采用单属性与多属性综合预测的方法。结果显示,该方法的应用既提高了工作效率,又增强了解释的客观性,减少了多解性,对断层和岩性边界的反映也更加清晰,还能随时监控解释结果的正确性,及时纠正解释过程中人为的错误。对同样条件下的三维地震资料解释具有一定的借鉴意义。

Due to the complex seismic geological conditions and high exploration accuracy requirements in Guojiahe exploration area,based on the extraction of a variety of seismic attributes,the method of expert optimization was used to select the attributes that are more sensitive to the geological structure of the study area for interpretation,and the method of single attribute and multi attribute comprehensive prediction was used in the interpretation process.The results showed that the application of this method not only improves the working efficiency,but also enhances the objectivity of interpretation,reduces the multiplicity of solutions,and reflects the fault and lithologic boundary more clearly.It can also monitor the correctness of interpretation results at any time and correct the human errors in the process of interpretation in time.It can be used for reference in the interpretation of 3D seismic data under the same conditions.
