Signal-noise ratio and resolution are two major factors for deciding whether rawseismic records are in good quality or not.The evaluation method recommended hereincludes the following steps:·preprocessing of raw seismic records which consists of trace editing,hand fil-tering,dynamic and static corrections·separating signals from noises by using mid value filtering and K-L filtering·estimating both the signal-noise ratio and the resolution in F-K domain,which are used to evaluate raw seismic recordsThis method has been proved quite useful.
