摘要对南翼山藻灰岩岩层储层特征及成因进行了系统研究。 - The northern qiangtang basin suonahu formation microfacies of carbonate rock is divided for the intraclast ash lithofacies , biological detritus ash lithofacies , oncolite limestone lithofacies , contain the calcium and alga ash lithofacies , marl lithofacies and pure microlite limestone lithofacies
羌北盆地唢呐湖组碳酸盐岩微相为内碎屑灰岩相、生物碎屑灰岩相、核形石灰岩相、含膏藻灰岩相、泥灰岩相和纯微晶灰岩相等6种微相。 - The results show that : 1 ) though the water environment of nanyisan is more muddy than others , algal can still grow ; 2 ) the composition and rock type of the algal limestone are complex , the main rock types include lettuce - like stromatolites , algal reef , digitate stromatolies , wave - like stromatolites and so on ; 3 ) the deposits of algal limestones were formed in low - energy peritidal to subtidal high - energy environment of lakeshore slopes , sliding under the action of gravity and some other factors and become slump mixosedimentite layers ; 4 ) the physical property of algal limestones layers is better than others ; 5 ) the genetic development of the sediment decides that the single deposit is small , distributive and thin - layed
结果表明，南翼山藻灰岩沉积水体环境相对浑浊，但藻类仍能生长；该区藻灰岩岩石组成及类型复杂，主要的藻灰岩岩石类型有包心菜状叠层石、藻礁、指状叠层石、水平波状叠层石等；其主要为滨岸斜坡上低能潮上环境至高能潮下环境形成的沉积体，在重力等因素的作用下产生滑动或滑塌形成的微生物成因的滑塌混积岩；岩层物性好于其它岩层；藻灰岩层的成因决定了该地区单个沉积体规模小、分散、层薄。
