Characterization method of heterogeneity for Chang 8 tight reservoir in Honghe oil field, southern margin of Ordos Basin

摘要: 鄂尔多斯盆地南缘红河油田长8致密油成藏条件异常复杂，地质“甜点”小而分散，油藏非均质性极强。以红河36井区为例，从影响油藏富集高产的主控因素出发，重点开展“储层质量、裂缝、含油性”三大强非均质性表征，再结合产能评价建立油藏非均质性综合表征模型，更客观地呈现油藏地质特征。从微观和宏观角度建立基质储层分类标准，探索沉积成岩共控储层发育机理，形成“沉积要素控制成岩相，成岩相控制储层质量”的储层非均质性表征方法，从而明确分类储层平面分布；基于不同级别断缝带对油气富集的控制作用，建立多尺度裂缝带分级方案，井震结合开展分级预测，定量表征米级到千米级裂缝带分布；以井点含油性分析为基础，结合油水分布模式，建立含油饱和度场，定量表征含油非均质性；在此基础上，叠加三大强非均质性表征结果，建立致密油藏非均质性综合评价模型，明确分类储量及开发目标分布。Abstract: Due to the complexity of accumulation conditions of Chang 8 tight reservoir in Honghe oil field, the southern margin of the Ordos Basin, the geological "sweet spots" are small and scattered, and the reservoir is remarkably heterogeneous. The Honghe 36 well block of the Honghe oil field was taken as an example in this paper, based on the main constrains for reservoir enrichment and production, three major heterogeneity characterizations, including reservoir quality, fractures and oil-enrichment, were carried out, and then combined with evaluation on productivity. A comprehensive characterization model for reservoir heterogeneity has been established, which can represent the geological characteristics of the reservoir. A classification standard for matrix reservoirs was established from the micro and macro scales to discuss the formation mechanism of reservoirs constrained by sedimentary and diagenetic factors. A characterization method for reservoir heterogeneity that "sedimentary elements constrained diagenetic facies, and diagenetic facies constrained reservoir quality" was proposed, which clarified the plane distribution of reservoirs. Based on the constrains of different grades of fracture zones on oil and gas enrichment, a multi-scale fracture zone classification scheme was established. Well logging and seismic data were combined to carry out hierarchical predictions to quantitatively characterize the multi-scale fracture zones from meter scale to kilometer scale. The oil-bearing capacity of wells was discussed, and combined with oil and water distribution pattern, an oil saturation field was established to quantitatively characterize oil-bearing heterogeneity. On this basis, three strong heterogeneity characterization results were superimposed to establish a comprehensive evaluation model for tight reservoir heterogeneity, which was used to clarify development target distribution.
