摘要：

在礁滩型碳酸盐岩储层中，沉积对储层发育的控制作用至关重要。以川东北普光和元坝地区的下三叠统飞仙关组台地边缘浅滩相储层为例，在沉积背景及其演化分析的基础上，研究了飞仙关组沉积亚相及微相发育特征，划分并描述了典型钻井储层高频旋回，讨论了层序演化对储层发育的控制作用，高频旋回发育及其与孔隙发育的相关性、相对海平面变化与储层非均质性的关系，以及沉积、成岩环境对储层早期孔隙发育的控制作用。

Abstract:

Sedimentation is one of the key controlling factors in the formation of the reef and shoal carbonate reservoirs. This research studied the Lower Triassic Feixianguan shoal reservoir of marginal carbonate platform facies in the Puguang and Yuanba area, northeastern Sichuan Basin. The sedimentation background and its evolution history were studied before the microfacies analyses were conducted. The highfrequency cycles were divided and described based on drilling well data. The controls of stratigraphic sequences on reservoir formation, highfrequency cycles on porosity distribution, relative sea level fluctuation on reservoir heterogeneity, as well as early depositional and diagenetic environment on early porosity formation were discussed.

Key words: sedimentary facies, highfrequency cycles, reservoir formation, Feixianguan Formation, northeastern Sichuan Basin
