The imaging software system of wave equation prestack migration

Prestack depth migration (PSDM) based on wave equation is not only applied in the complex structure imaging, but also used for the lithology imaging in the complex geological condition.The imaging software system of wave equation PSDM (iCluster) is developed successfully.Its main modules include project management, data management, migration velocity analysis, structure model building, velocity model building, seismic migration imaging processing, 3-D visualization and assistant computation, etc. Accurate velocity model building, advanced PSDM, high efficient parallel computing, 3-D visualization and performance optimization are characteristic techniques.SEG/ EAGE 3-D salt dome model data test shows imaging of the salt dome boundaries and faults are very clear. In real data PSDM, We can accomplish 2-D/3-D prestack time/depth migration using this software system.Imaging of the steep structures from Biyang trap in Henan oil field and buriedhill interiors in Shengli oil field are very well.
