Carbonate reservoir is one of the main controlling factors of hydrocarbon accumulation. But the exploration proved that high-quality reservoir and commercial hydrocarbon flow had no absolute corresponding relationship, high-quality reservoir just was the necessary condition of hydrocarbon accumulation. It was found that local construction highs had an important control function to hydrocarbon accumulation. So it has a realistic guiding significance to exploration that enhancing the detailed study on carbonate fracture-cave unit. This paper selected Well Block ZG7 with complex oil-water relationship as a case, and comparative analyzed the structural position, structural characteristics, reservoir characteristics and fluid producing status before and after acid fracturing. It indicated that structural position of fracture-cave unit had a crucial control function to the fluid property in it, whose high accumulated hydrocarbon and the low was water commonly. The structure of facture-cave unit had a close relationship with the fluid producing status, which differed from the variation of fracture-cave unit structure. Carbonate reservoir and local construction were the important controlling factors of hydrocarbon accumulation, under the background of high-quality reservoir, local structures and structural highs were the favorable accumulation areas.
