Abstract:In view of the characters that the top interface of large-scale Ordovician buried-hill is violent fluctuation and interior karst changes greatly in both lateral and vertical directions,and taking further improving the imaging precision of carbonate fracture-cave type's reservoir and minor faults in Tahe Oilfield as object,we carried out the study on fine imaging technique of fracture-cave type's reservoir,which focuses on fine and object-oriented 3-D seismic data processing and prestack time migration method,built up fine fracture-cave type's reservoir imaging techniques taking the 3-D tomographic static corrections and near-surface model technique,prestack frequency-shared denoise,3-D hi-fi processing,series deconvolution,3-D velocity analysis and iterative surface-consistent residual static corrections,3-D high-precision migration velocity model-building technique and 3-D prestack time migration as bases,which made the imaging quality of fracture-cave type's reservoir,imaging precision of weathered interface,description of fault feature,lateral resolution,S/N ratio and hi-fi of data be greatly improved and the configuration of Mid-Lower Ordovician weathered interface be finely described,laying the foundation for the prediction of carbonate fracture-cave type's reservoir and semi-quantitative to quantitative prediction of geometric space of fracture-cave type's reservoir.
