优势谱聚焦联合储层反演技术在M油田的应用

Application of Dominant Spectrum Focusing Combined Reservoir Inversion Technology in M Oilfield

以M油田为例,从地震资料优势频带解析与岩石物理深入剖析的角度,探讨基于优势频率融合的联合储层反演技术。首先,联合开展叠前同步反演、波形指示反演和地质统计学反演;其次,提取各反演成果的优势频率进行融合,开展融合体数据解释;最后,预测流二段薄储层分布特征,进而指导M油田的开发实践。基于反演结果,分别提取这几种不同反演方法的优势频段进行融合反演,并用于识别厚8 m左右的薄储层。

Taking M oilfield as an example,this paper explores reservoir inversion technology based on dominant frequency fusion from the perspective of analyzing the dominant frequency band of seismic data and rock physics.Firstly,jointly carry out pre-stack synchronous inversion,waveform indication inversion,and geostatistical inversion;Secondly,extract the dominant frequencies of each inversion result for fusion,and carry out data interpretation of fusion volume;Finally,predict the distribution characteristics of thin reservoirs in the second section of the flow,and guide the development practice of M oilfield.Based on these results,the dominant frequency bands of these different inversion methods are extracted and used to identify thin reservoirs with a thickness of 8 m.
