| 摘 要： | 以沉积学 、储集层地质学和测井地质学为基础,依据岩心观察,结合沉积物粒度等沉积相标志的再认识,研究了泌阳凹陷安棚油田扇三角洲致密砂岩储集层的微相特征。该油田的扇三角洲沉积可进一步细分为扇三角洲前缘和前扇三角洲2个亚相及6个微相,详细阐述了各徽相的沉积、物性特征以及展布规律,总结了微相与油气分布的关系,指出中远水下分流河道及河口坝为油气聚集的有利微相。

| Abstract: | The microfacies feature of tight sandstone reservoir in fan delta of Anpeng oilfeidl in Biyang sag is studied on the basis of sedimentology, reservoir geology, logging geology and core data, combined with the recognition of sedimentary facies signs like sediment granularity. The fan delta can be subdivided into two subfacies and three microfacies. The characteristics of deposits, petrophysical property and distribution of these microfacies are elaborated. The relationship between the microfacies and oil-gas distribution is analyzed. It is suggested that the mid-distal subaqueous distributary channel and channel-mouth bar are the favorable microfacies for oil-gas accumulation. |
