摘要
鄂尔多斯盆地姬塬地区延长组长8段油藏为典型的特低渗透油藏,其储层物性、含油性等非均质程度强,储层参数平面分布和油藏展布规律复杂。基于"岩心刻度测井"的思想,在测井资料标准化基础上,本文构建了储层参数精细解释模型,通过测井多井解释明确了储层物性和含油性的平面分布规律;应用测井多井评价技术,基于不同的测井相特征对比、划分小层砂体,并依据不同砂层物性和含油性特征的差异开展了岩性油藏精细对比研究,明确了研究区特低渗透油藏控制因素和展布规律,实现了基于测井多井评价方法的特低渗透复杂岩性油藏精细评价。
With a strong heterogeneity and oil-bearing property,the member Chang 8reservoir of Yanchang Formation in Jiyuan area,Ordos Basin is characterized by typical extra-low permeability. And it has complex reservoir parameters and reservoir distribution.This paper proposes an approach for evaluation of this kind of reservoirs.Based on core calibrating logging data,we build fine interpretation models of reservoir parameters according to logging data standardization.Through multiwell logging interpretation,the reservoir distribution and oil-bearing property are determined. Small sand bodies are identified based on different logging facies,and lithologic reservoir contrast is obtained by different physical and oil-bearing properties.Finally the control factors and distribution rules of extra-low permeability reservoirs in the area are defined.Therefore fine evaluation of extralow permeability reservoir is realized based on multi-well logging.
