摘要： 通过对准噶尔盆地乌尔禾地区二叠系风城组白云岩储集层的成因及分布规律研究,发现其分布主要受有利沉积相带控制,在扇三角洲发育处白云岩的发育明显受到抑制,扇三角洲前缘扇体之间的湖湾区成为白云岩分布的主要区域。白云岩主要为陆源物质供给较少的静水、微咸浅湖环境下沉积的灰泥质沉积物在成岩过程中随 Mg2+ 含量变化而导致强烈白云岩化而形成的。

Abstract: This paper analyzes the origin and distribution of dolomite reservoir of Permian Fengcheng formation in Wuerhe area in Junggar basin, and proposes that the distribution of dolomite reservior is controlled by sedimentary facies. The occurrence of dolomite in fan delta is obviously restricted, and its main distribution area is the lake-bay area among the front fans of the fan delta. The dolomite is generally formed in environment of slightly salty shallow lake with still water, where the terrigenous mud sediments are changed by strong dolomitization with varied Mg2+ content during their diagenetic process.

Key words: Junggar basin, Wuerhe, Fengcheng formation, dolomite, reservoir, origin
