摘要
二连盆地在早白垩世阿尔善组腾一下亚段之间发育一套由云岩类、泥岩类、云质粉砂岩类、沉凝灰岩类、酸性喷出岩类及沸石岩类等组成的特殊岩性组合。从已钻遇井取芯资料和已开发油气藏研究入手,结果表明:"特殊岩性段"储集空间主要为孔-缝复合型,油气藏为受"特殊岩性段"分布控制的自生自储、无明显油水边界油气藏,是二连盆地新的油气藏类型。
There is a special lithologic between K1 ba and K1bt1 in Erlian basin,which consist of dolomite,dolomitic siltstone,volcanic tuff,acidic effusive rock and zeolite.Based on core and developed reservoir data,the results show that the special lithologic reservoir space is mainly hole-seam composite,and the special lithologic have significant effect on their reservoir style.The reservoir is self-generation and self preserved and no obvious oil-water boundary,which is a new reservoir style in Erlian Basin.
