摘要
The 3D multi-component seismic exploration was carried out in the western Sichuan Basin for the previous use of 3D P-wave seismic data failed to precisely predict fractures in deep-seated tight sandstones of this area,especially disabling to solve the problem of determining giant net-fractured systems. The 3D multi-component seismic exploring technique can predict the azimuth and density of the fracture development by means of P-and S-wave seismic attributes,azimuthal anisotropy and S-wave splitting phenomenon,and it contains various predicting methods and technical processes for different-size fractures. A full application of this technique preferably resolved the problem in predicting multi-size net-fractured systems of ultra-tight sandstones of the Xujiahe Formation in the Xinchang gasfield,western Sichuan Basin and offered some credible proofs for the well planning in gas exploration and development.
