The study on the methods for the depositional stage division of Glutenite body——a case of the actic region in the north of Dongying Depression

Based on well-seismic combination and analysis of sedimentary cycle on a single well, the identified sequence interfaces are calibrated on the seismic section for the landscape correlation and trace of large-scale sedimentary stage. Then the sequence stratigraphic interpretation system of OpendTect software is applied by using the dip guiding median filtering processing, data driven mode tracing and Wheeler domain automatism transformation to finish automatism tracing and transformation of small layers in glutenite fan body. According to the analysis of positive and negative cycles, the glutenite fan body in S3 and S4 Members of the northern belt of Dongying is divided into 14 stages. The method is being recommended to be applied more widely in fine division of stratum and sedimentary stages than other well-seismic combination methods.
