【摘要】 塔里木盆地石炭系生屑灰岩段的主要沉积相类型划分为滨岸相和碳酸盐台地相两大类。通过分析建立了碎屑滨岸至碳酸盐台地和碳酸盐台地内部两种沉积模式。碎屑滨岸和混积滨岸相区主要分布于塔北地区 ,蒸发台地相区分布于塔中 4井以东地区和曲苦恰克地区 ,并且是优质白云岩储层的主要分布地区 ,其它地区则属于局限台地和半局限台地相区。最后论述了生屑灰岩段的沉积相演化更多还原

【Abstract】 The sedimentary facies of Carboniferous Bioclastic Limestone Member is mainly classified into shore and carbonate platform facies in Tarim basin. In the paper, two depositional models are established by comprehensive analysis: they are the clastic shore to carbonate platform model and the carbonate intraplatform model. Terrigenous clastic and mixed shore facies are mainly distributed in the north of Tarim basin. Evaporate platform facies are spread in the east of the 4 wells in middle Tarim and in Qikuqiake area, and the best dolostone reservoirs are largely located there, too. In other areas the restricted and semi restricted platform facies are distributed. At the end of the paper, we discuss the sedimentary facies evolution in Carboniferous Bioclastic Limestone Member.更多还原
