摘要

上丘里塔格群(下奥陶统)致密泥微晶灰岩是塔里木盆地北部重要油气勘探目的层之一.其储集空间类型属于以微孔隙为主的缝合线-微孔型非常规储层.徽孔成因以溶蚀作用,特别是深部溶蚀作用为主,这是我国新近发现的致密灰岩徽孔储层.这一发现具有重要意义,为塔北油气勘探提供了科学依据,开辟了我国碳酸盐岩储层的新类型.同时也为进一步研究微孔成因、演化等提供了条件.

Abstract

The compacted minimicritic limestones of the Upper Qiulitage Group( Lower Ordovician)are one of the prospecting targets in the north Tarim Basin.The type of the reservoir pores is dominated by micropores,attributed to an unconventional type of suture-micropore reservoir.The micropores formed preponderantly under corrosion,particularly the deep corrosion.It is a compacted limestone reservoir with micropores discovered recently in the country,which would be significant for it provides scientific basis for petroleum exploration,and renew the types of carbonate rock reservoir in China.Meanwhile it makes the studies available on the origin and evolution of micropores.
