摘要：
Compared with the sequences of marine basins, sequence stratigraphic architecture of non-marine basins is characterized by multi-variation and uncertainty. Migrated sequence stratigraphic architecture is one non-normal type in the evolution of continental lacustrine rift basin, which is rare documented. Based on the sequence stratigraphic units analysis of Paleogene Wenchang Formation of Huizhou and Enping sags, Zhu I Depression, Pearl River Mouth Basin, this paper defined the concept of migrated sequence stratigraphic architecture and divided into autogenic and allogenic migration. Autogenic migrated sequences are mainly controlled by horizontal displacement of low-angle syndepositional normal fault, whereas allogenic migrated sequences are controlled by the different tectonic activation episodes of boundary fault on both sides of the basin. In other words, autogenic and allogenic migrated sequences are controlled by one and two syndepositional boundary fault, respectively. During the lateral migration of sequences, reservoirs and source rocks controlled by sequence stratigraphic units at multiple scales also migrate and stack laterally. This helps the high-efficient configuration of hydrocarbon accumulation factors (e.g., source rock, reservoir, and seal) to generate reservoir combination with multiple blocks and multiple strata. © 2016, Editorial Department of Earth Science.
