The reef limestone reservoir of Zhujiang Formation is an important exploration and development reservoir of the LH oilfield in South China Sea. In order to explore the fracture development situation,the geophysical fracture detective technology is used to predict the fracture features combined with the characteristics of the regional diagenesis and structure and on the basis of the marine seismic data gathered in the narrow azimuth.The applicability of AVAZ technology,the far-near offset attributes difference technology,and the stress field analysis technology based on pre-stacked data is analyzed and a suite of fracture detective technologies for gathering seismic data in narrow azimuth are summarized.Layer b2 and the reservoir fracture features are successfully predicted by the combination of these three different technologies.In order to get the precise results,one must compare these three methods so that the distribution of Layer b2 and the targets fracture can be obtained.The production wells verify that the prediction fractures consistent rate is more than 75%.
