The influence of multi-scale fractures on 3D geological modeling of carbonate reservoir: An application case analysis of Anyue Gas Field

Abstract The carbonate reservoirs of the Dengying Formation in the Sinian system are well-developed, but with strong heterogeneity and natural fractures. Conducting three-dimensional fracture modeling research has important guiding significance for deepening the geological understanding and development plan formulation of this gas field. This paper starts from three-dimensional high-precision seismic data, distinguishes cracks of different scales, and uses deep learning technology and Aberrance detection technology to carry out multi-scale crack prediction of the target layer in the research area. Based on this, high-precision crack modeling work is carried out. The on-site construction results show that the natural crack model established by this technology series has high accuracy and has promotional application value in the next step of improving gas field development efficiency.
