摘要： 针对鄂尔多斯盆地上古生界二叠系山西组砂岩岩性气藏非均质性强、开发早期井少、井距大、储集层预测难的特点,通过地震多种属性分析,并充分结合井资料,在建立储集层参数与地震属性参数的相关关系后,利用井资料对得到的属性反演数据进行校正,能够提高无井区储集层特征描述的可靠性。地质统计分析认为,利用构建的煤层校正系数可以较为准确地恢复砂岩对均方根振幅属性的敏感性。根据校正后的均方根振幅属性特征与砂岩厚度的拟合关系,能够直接对储集层进行平面分布预测和描述,并对研究区划分沉积相提供重要的依据。

Abstract: The Shanxi sand layer of Permian in Ordos basin is a lithologic gas pool with strong heterogeneity and characterized by few well, big well spacing and difficult prediction of reservoir quality in its early stage of development. Through the seismic attributes analysis, combined with drilling/well data, the relationship between the reservoir parameters and the seismic attribute parameters is set up. By correction of the attribute inversion data from using the drilling/well data, the reliability of reservoir characterization in non-well area can be improved. The geologic statistical analysis shows that available coal-bed correction factor could be applied to more properly get back the sandstone sensitivity to the root-mean-square amplitude attribute. According to fitting relation between the adjusted root-mean-square amplitude attribute characteristic and the sandstone thickness, the plane distribution prediction and description of the reservoir can be directly conducted for the purpose of providing references for the sedimentary facies divition in this studied area.

Key words: Ordos basin, seismic attribute, correction factor, reservoir rock, prediction
