Seismic sedimentology mainly uses 3D seismic information and modern geophysical technology to study sedimentary systems,sedimentary facies spread and its evolution history.The western Mahu slope close to the oil-generated sag in the vicinity of northwest margin fault belt of Junggar basin and has the favorable hydrocarbon accumulation conditions and rich oil and gas resources.But there is deep exploration bed of interest,strong heterogeneity of reservoir,and relatively thin reservoir.Based on study of regional structural and sedimentary conditions in the Junggar basin,the structural traps are not well-developed,but the composite traps such as lithological and stratigraphical trap are favorable developed.Accordingly,we carry out seismic sedimentology on the western Mahu slope of Junger basin in the 3D seismic area.We use a series of layer slices and drilled core information to dynamically interpret the target zone and determine the sedimentary facies in the study area.
Key words： Seismic sedimentology; Junggar basin; 90°; phase shift; Frequency division; Layer slicing.
