摘要：

A comprehensive study of cores, thin sections, drilling, and imaging logging data indicates that fractures and caves are dominating in the Ordovician reservoir in the Maigaiti slope of Tarim Basin. The Ordovician reservoir is developed to varying degrees in different zones of the slope area, with the best quality (including two sets of high quality reservoir) found in the east area of Yubei. The Ordovician reservoir can be classified into three types according to its genesis, i.e., burial and epidiagenetic fracture-cave reservoir, unconformity karst reservoir, and bedding deep-underflow karst reservoir. The fracture-cave reservoir of Yingshan Formation is controlled by ancient landform and fractures, whereas the geological conditions of Penglaiba Formation support the development of bedding deep-underflow karst reservoir. A geological development model for different types of Ordovician reservoirs is established and then used in combination with seismic reservoir prediction data for predicting the distribution patterns of different types of reservoirs in the Maigaiti slope. The eastern fault-fold wing and fault-depression areas as well as the mid-western karst hill-belt are identified as favorable zones for reservoir exploration in Yubei area.
