摘要
以羊三木潜山储层为预测对象,在地震分频技术原理和技术特点基础上,采用长短时窗相结合的频谱分解算法,既利于准确刻画薄层,又可保证信号真实性。通过结合前期的地质资料,应用基于长短时窗相结合频谱分解算法的地震分频技术,分析了羊三木潜山储层不同时期的沉积相类型,对不同类型的单频地震响应赋予了更详实的地质意义,更加便于进行识别储层。
Targeting at the Yangshanmu buried-hill type reservoir for prediction,the principle and features of seismic frequency demultiplication technology is discussed to illustrate the application of spectral decomposition algorithm with long- short time windows combined,is favorable for precisely description of reservoir and ensures signal fidelity,By use of early geologic information and the seismic frequency demultipltralum technology based on spectral decomposition algorithm with long- short time windows combined,the types of sedimentary facies at various stages in the Yangshanmu buried- hille type reservoir is analyzed and provides mure detail geologic significance to various types of single frequency seismic response,facilitating reservoir identification.
