针对埕岛油田东营组特定砂泥岩互层的组合特点,根据地层岩性的不连续性造成的波动奇性传播,本文利用波动方程对地震资料进行奇性分形反演以识别不同的地层,从而达到对储层进行描述的目的。本文首先从三维数据体中抽取所要处理的测线,由SEQ-Y格式转换成奇性分析的输入格式,然后进行神经网络反褶积处理。在此基础上进行奇性分析处理和分形分维描述,最后从井资料出发,与测井、沉积相资料结合起来,对处理结果做出解释并建立储层描述模型。实际应用表明本文方法切实可行。
According to the characteristics of interbedded sand-shale interbeds in Dongying Formation of Chengdao Oilfield, based on the undulating singularity propagation caused by the lithology discontinuity of the strata, this paper uses the wave equation to perform singularity fractal inversion of seismic data to identify different strata and thus Achieve the purpose of describing the reservoir. In this paper, we first extract the line to be processed from the three-dimensional data body and convert it from SEQ-Y format to singularity analysis input format, and then carry out neural network deconvolution. On the basis of this, singularity analysis and fractal fractal description are carried out. Finally, from well data, combined with well logging and sedimentary facies data, the processing results are explained and a reservoir description model is established. Practical application shows that this method is feasible.
