摘要
The Ordovician carbonate rock is the main oil producing reservoir in Tazhong area. Synthesizing the information from cores, well logs, outcrops and seismic data, a suitable method for multi-approach characterization the Ordovician carbonate fractures in Tazhong area is proposed. The paper suggests that the distribution of fractures in the Ordovician carbonate rocks is related with the lithology, regional stress field and structural position, and appears in SN zonation, EW blocks and fault control in north slope of Tazhong area, Tarim Basin.
