储层非均质性包括微观和宏观非均质性。通过对岩心薄片、铸体薄片、电镜、Ｘ－衍射等试验数据以及测井储层评价数据分析，揭示冀东北堡油田中区东营组储层非均质特征为：储层岩石成分复杂，不稳定组分含量高，分选差，含泥沙质结构；压实作用、溶蚀作用及粘土矿物转化现象普遍，成岩变化大；中小孔细喉结构，连通性差，微观非均质性强。宏观非均质性较强，层内纵向上渗透率差异明显，渗透率非均质参数值较大；层间非均质程度与层内的相近；平面非均质性强，砂体连通性差，有效砂层系数较小，非均质参数在平面上变化大。采用压裂措施，降低储层非均质性，改善储层连通性，可提高开发效果。
Reservoir heterogeneities include microscopic and macroscopic heterogeneities. By analyzing the data of core sheet, casting thin film, electron microscope, X-ray diffraction and other data of well logging evaluation, it is revealed that the reservoir heterogeneity in Dongying Formation of Central Area of Jibei Beibu Oilfield is as follows: The content of stable components is high, the sorting is poor and sandy structure is included. Compaction, dissolution and conversion of clay minerals are common, diagenetic changes are great. The throat structure of small and medium holes is poor in connectivity and microscopic heterogeneity. The macroscopic heterogeneity is strong, the permeability in the layer is obviously different in the longitudinal direction, and the value of the heterogeneity of permeability is relatively large; the degree of interlayer heterogeneity is similar to that in the layer; the plane heterogeneity is strong and the sandbody connectivity is poor , The effective sand coefficient is small, the heterogeneous parameters vary greatly in the plane. Using fracturing measures to reduce reservoir heterogeneity and improve reservoir connectivity can improve development effectiveness.
