The fracture characteristics and distribution of volcanic reservoir of Huoshiling Formation in Wangfu fault depression were studied based on fractures in rock cores and thin sections��combined with imaging logging and seismic data�� The fractures of volcanic reservoir are classified into the primary and the structural- secondary fracture�� The primary fracture has less contribution to improve the property of volcanic reservoir��while the structural- secondary fracture makes sence for the reservoir due to its wide openness and long extension�� High- conductive frac- ture��high- resistant fracture��microfracture and drilling induced fracture can be identified with Formation MicroScanner Image (FMI)�� Typically��high- conductive fracture and microfracture are efficient�� The fracture of fracture of volcanic reservoir can be divided into the northern��the middle and the southern zones��with different fea- tures of high- conductive fracture strike and structure�� In the northern and southern zones�� the structure is controlled by straight faults��and the high- conductive fractures are in two dominant strike directions�� While the structure in the middle zone is principally controlled by cross- faults��and the high- conductive fractures are only in one prevalent strike�� The mean density of fracture in the middle zone is the highest among the three��and the diagram of dip attitude also shows that the middle zone is the favorable area�� Thus��the middle zone is a key area for exploration and well deployment��
