High precision seismic data is the basis of subtle reservoir prediction.Now, many people pay attention to the problem how to improve the resolution of the seismic data by acquisition and processing.There are many factors that effect the resolution of seismic data and for different area and different targets the demands are not same,so it must make concrete analysis of concrete conditions. In the east,there are many faults and the structures are complex,and in the west,the Tarim basin,there are many structures with low relief that are developed.It's important to improve the resolution of seismic data for middle and deep beds as well as for eastern and western area.In the paper,some factors affected the resolution of seismic data are discussed from the angles of both acquisition and processing.Some suggestions are put forward for these problems.
