摘　　要：受成岩作用与构造作用等因素的影响,礁滩型储层非均质性较强,而定量表征其非均质性对储层预测及油气田开发均具有重要的指导意义。以普光气田礁滩型储层为例,通过优选综合指数法及渗透率参差系数法对该储层层间非均质性进行了定量表征。结果表明:2种表征方法的结果一致,且与地质认识相符。避免了单参数表征带来的不确定性,同时也避免了表征参数无界的影响。以上方法实现了对储层层间非均质性的定量表征,真实地反映了普光气田礁滩型储层层间非均质性较强的特点,并可为国内外同类研究提供参考。Reef flat reservoir is often influenced by diagenesis and tectonism, which leads to the extremely strong heterogeneity. Therefore, quantitative characterization of the heterogeneity can effectively guide the reservoir prediction and oil-gas field development. Taking the reef flat reservoir of Puguang Gas Field as an example, we selected aggregate index method and permeability diversity coefficient method to characterize the interlayer heterogeneity. The result shows that the two methods have consistency in the assessment result, and the assessment result is consistent with geological cognition. The two methods can not only solve the uncertainly problem of single parameter characterization, but also avoid the impact of unbounded parameters. The methods can realize the quantitative characterization of reservoir heterogeneity, and truly reflect the reef flat reservoir characteristic of stronger heterogeneity, which provides reference for similar research.
