本文基于孤店断陷两口井现有的化验分析资料,对孤店断陷扇体储层分相带进行评价,首先从扇体不同相带在地震和测井上具有不同的响应特征入手,利用物性数据、薄片、压汞、X—衍射分析粘土矿物等手段综合分析扇体不同相带储层微观特征方面的差异。研究表明,扇中前缘相带物性相对较好,孔隙发育,孔隙结构好,孔喉分布相对均匀,是深层碎屑岩储层的有利勘探方向。
Based on the existing laboratory analysis data of two wells in orphan fault depression, this paper evaluates the fractured phase zone of fan reservoir in orogenic fault depression. Firstly, starting from different response characteristics of seismic facies and well logging, By means of physical property data, flake, mercury intrusion and X-ray analysis of clay minerals, the differences of microfacies in different facies belts are comprehensively analyzed. The results show that the facies of the front margin of the fan is relatively good, the pores are well developed, the pore structure is good, and the pore-throat distribution is relatively uniform, which is a favorable prospecting direction for the deep clastic reservoir.
