How to effectively applying seismic data for dividing sequences & sedimentary cycles and tracing inner sequences is always a technical problem in sequence stratigraphy.The seismic Wheeler transform technology is a new method developed in recent years,which combines sequence stratigraphy and seismic sedimentology together better.Therefore,by using this method,we can study stratigraphic sequences and sedimentary phases with 3-D high accuracy seismic data to maximum.Firstly,the basic principle and implementation of the seismic Wheeler transform technique was explained systematically.Secondly,the validity of the method was verified by using delta front sedimentary geological model.Finally,this method was used in the division of cycles and stages of delta in Dongying Depression,combined with logging data and time-frequency analysis method,the sequence classification scheme was redefined.As a result,middle Es3 of Dongying Delta was divided into nine fourth-level sequences.
