摘要
通过对岩心物性、铸体薄片、压汞以及核磁共振等进行岩石物理试验分析,利用压汞资料所反映的岩石孔喉半径大小信息以及喉道分类标准对岩心核磁测量的τ2(横向弛豫时间)谱进行刻度,划分为小孔、中孔和大孔共3部分;利用其3部分所占整个孔隙空间的比例进行了基于微观孔隙结构特征的岩心分类标准方法研究。以冀东油田某区块为例,建立了研究区块的储层分类方法和标准,实现了对储层连续地、有效地分类,在该区块取得到了较好的应用效果。
A rock physical experimental analysis was conducted based on the data of core property,casting slice,mercury intrusion and nuclear magnetic resonance(NMR).The NMRτ2 spectrum was divided into big,medium and small pores according to throat classification standard and the data of rock pore throat radius size calculated by mercury injection data.Different proportions of pore space of the 3kinds of pores were used to research the core classification standard method of microscopic pore structure and establish reservoir classification method and standard.By taking a block in Jidong Oilfield for example,classification method and standard of the block are studied,a continuous and effective reservoir classification is realized and better application effect is obtained in NMR of the block.
