摘要
The carbonate karst reservoir in Yingmaili-Halahatang area which gained breakthrough recently in Tarim Basin was controlled by lithology, karstification and tectonic evolution. Reservoir space according to the combination of characteristics of the Ordovician reservoir is divided into four categories: vuggy,fracture-vuggy, cavern, fracture. The types of Yingmaili area are mostly fracture and fracture-cavern, while the types of Halahatang area are vuggy and fracture-vuggy. With the study of karstification process,it is pointed that the proto-pores and the sedimentary facies were the basic factors of second pores forming,and karstifications were the main factors which controlled the reservoir development, and fractures during the tectonic evolution were the key factors which accelerated the reservoir development and controlled its distribution.
