Abstract：Applying seismic data to predict the fracture is not only relative to real effects of oil-gas development, but also a front subject of seismic exploration.Adopting the idea companing the prediction of lithology with the prediction of fracture,the paper first used logging-constrained seismic inversion to clarify the distribution of igneous rock in Shang-741 well zone,then,carried out the non-isochronal fracture identification along the top and bottom interfaces of igneous rock by using 3-D multi-scale edge detection technique,finally conducted the prediction of fractures by combining with the structural interpretation and drilling and logging data and presented the areas favorable for oil-gas distribution.The predicted results showed that the method has advantages of high-predicted precision and better fit with practice, which could guide arrangement of well site in this area and have higher practical value.
