Application Of Q-Prestack Depth Migration In Banqiao Area

Along with the progress of the seismic data processing technology at present,for the resolution of seismic data of deep demand is higher and higher,Q prestack depth migration technology as an effective means of true amplitude processing gradually into people's horizons.The key of the pre-stack depth Q migration technique is the accuracy of Q model and the application of Q migration technology.This article explores the cause of formation and influence factors of the main causes of attenuation,and compared the current mainstream of several different ways to calculate the Q value of the advantages and disadvantages,and compares different methods of true amplitude migration.Banqiao area processing and interpretation and combined with the "integration" research project to study the Q value in the process of actual data processing method of calculating,it is concluded that the integrated use of different Q value calculating method to improve the Q model accuracy conclusion,Banqiao area at the same time use Q migration method for seismic data processing research,by comparing the conventional excursion of the can see Q and Q migration can effectively improve the resolution of seismic data of deep,has the high fidelity.It is proved that Q offset can meet the requirement of higher seismic resolution.
