Optimization of fracture reservoir prediction technology——with reservoir of Daanzhai member of Jurassic in Fulin region as an example

Through a comprehensive analysis of sedimentary facies distribution,geological structure,and known well drilling data and gas test situation in Fulin region,it is found Daanzhai member of the target area is with low porosity and low permeability,high gas yield and fracture developed.By using post stack and pre stack seismic data to study fracture reservoir,and predict fracture of Daanzhai reservoir.Comparing the actual results achieved by various methods,we optimized the ant tracking technology and fracture inspection technology based on pre stack anisotropy,which can provide an effective basis for comprehensive description and searching of the fracture in the study area.
