本文根据岩心和铸体薄片观察与储层物性分析,系统研究了鄂尔多斯盆地靖边气田北部马五14亚段的储层特征.结果表明:马五14亚段储集空间以晶间孔、溶蚀孔洞和微裂缝为主,为典型的低孔低渗型储层;溶蚀作用对储层的发育具有决定性作用.根据储层物性和产量等参数,将马五14亚段划分为4 类储层,其中Ⅰ、Ⅱ类为优质储层,主要分布在研究区西部和北部.

The Ma-514 carbonate reservoirs in northern Jingbian Gas Field, Ordos Basin are explored in detail on the basis of cores, cast sections and physical properties of the carbonate reservoirs. These carbonate reservoirs contain intercrystal pores, solution openings and microcracks, indicating a kind of low-porosity and low-permeability reservoirs. The solution is thought to be decisive of the reservoir development. The Ma-514 carbonate reservoirs may be classified into four categories, of which Types I and II are assigned to the high-quality reservoirs in the western and northern parts of the study area.
