阿尔凹陷凝灰质含量对渗透率影响分析

Influence of Tuffaceous Content on Reservoir Permeability in A'er Sag

以二连盆地阿尔凹陷低孔低渗储层为研究对象,在分析该区块地质特征、储层特征的基础上,进一步研究了凝灰质含量对储层渗透率的影响,从而得出凝灰质含量高是致使该区块渗透率低的主要原因,为进一步提高阿尔凹陷地区的储层综合评价,建立精细的渗透率解释模型奠定了基础。

The low porosity and permeability reservoirs of A'er Sag in Erlian Basin were used as research object and based on the analysis of geological and reservoir characteristics,the influence of tuffaceous content on reservoir permeability was further studied,the result indicates that high tuffaceous content is the main reason of low permeability in the area.It provides a basis for improving reservoir evaluation and establishing fine permeability explanation model in A'er Sag of Erlian Basin.
