Abstract：Buried hill reservoirs of Hexiwu structure belt of Langgu sag in Jizhong Depression,which had been discovered and proved,are Paleozoic Ordovician carbonate reservoirs with many caves and fissures.They have the following characteristics: strong heterogeneity,lateral variation in properties.The fissures are the most important predominant.So fracture prediction plays a vital role on accumulation conditions analysis and prediction of hill reservoirs in this area.Based on multi-attributes,such as coherent data,body curvature data,amplitude and frequency from new 3D seismic data,we predict and characterize the spatial distribution of reservoir's caves and fissures,and delineate favorable zones for development in the central north of Hexiwu structure belt.The drilling results show that the carbonate reservoirs developed many fissures with good hydrocarbon show,and that confirms our study is successful.
