摘要：
In order to investigate the distribution law of glutenite bodies in the stepped fault-ramp zone, establish a reasonable and reliable sedimentary filling pattern and effectively guide exploration decision-making, a flume sedimentation experiment was carried out with the stepped fault-ramp in Shengtuo area of Dongying sag as the base model, and the alternating sedimentary processes such as debris flow, paroxysmal flood, and traction flow was designed in the experiment. The results show as follows. The glutenite bodies such as nearshore subaqueous fans and turbidites are mainly developed in the stepped fault-ramp zone. The nearshore subaqueous fans are distributed in the first stepped fault-ramp zone, and the sedimentary filling characteristics of the fans are basically consistent with those of the shovel-like nearshore subaqueous fans in the fault ramp proposed by the predecessors. That is, the fan bodies fill the geodepressions and develop isolately in the early sedimentation stage, and then migrate and overlap to form larger contiguous regions in the late sedimentation stage. Turbidites are mainly developed in the second stepped fault-ramp zone. There are many dynamic filling types of glutenite bodies, such as fault transition zone filling, sublacustrine fan filling, step filling and migration-superposition filling. There is a genetic relationship between the glutenite bodies of the first and second stepped fault-ramp zone. Based on the understanding of sedimentary process and sand body development law, the oil-gas exploration has made another breakthrough in the second stepped fault-ramp zone of Shengtuo area. © 2022 Science Press.
