High-resolution sequence architecture and seismic sedimentology interpretation of fan delta
摘要
Abstract
High-resolution sequence architecture of fan delta in Oilfield A of Bohai Bay Basin is established and seismic sedimentology interpretation is conducted for interpretation of reservoir distribution.The comprehensive analysis proves that research on thick reservoir of fan delta follows principles of centering on description of main sedimentation area and treating different facies differently.Based on the reservoir correlation patterns,sequence boundaries of different levels, including 5 short-term cycles and 12 super short-term cycles from 1 mid-term base level cycle are recognized.4 strata slicing patterns of multiple fans,such as successive progradation,successive retrogradation,retrogradation to progradation and progradation to retrogradation,are summarized in terms of best option for seismic data of certain frequency,so as to accomplish seismic sedimentology interpretation in high-resolution sequence architecture.It shows that the fan bodies of 1 st and 2 nd Member of Shahejie Formation in Oilfield A expand at the first stage and then shrink gradually.Fan shape changes from skirt-rim pattern to ribbon pattern,which is in accordance with the division of sequence architecture.关键词
