In recent years, lacustrine tight oil and gas reservoirs and deep reservoirs closely related with deep- water sediment gravity flow deposits have attracted increasing attention in the field of oil and gas exploration and have become a research hotspot. Controlled by geomorphological features and boundary faults, the steep- slope zone of the faulted lacustrine basin hosts well- developed sedimentary fans caused by subaqueous sediment gravity flow, which has become a major target for tight oil and gas exploration as well as for the deep reservoir. This study selected the Upper Submember of the 4th Member of the Shahejie Formation (E s 4 s) in the Shengtuo area, Dongying depression, Bohai Bay basin, East China, as the study object. Based on the core, seismic, logging and mud logging data, sedimentary features and models of the deep- water gravity flow in the steep slope zoon of the terrestrial faulted lacustrian basin has been studied. The results show that sandy slide- slump deposition, sandy debris flow deposition, bottom current reconstructed deposition, turbidity deposition and deep lake mudstone deposition are five main sedimentary types of the deep- water deposition system in the research area. Three types of microfacies of deep- water gravity flow deposition in this area have been identified according to the patterns of different lithofacies combination: gravity flow channel, ligulate sandy- debris and distal lobe. The E s 4 s deposition experienced a transition from lowstand system tract to transgressive system tract to highstand system tract. The Chunxia sub- submember experienced the episodic faulting activities of the Shengbei fault during the lowstand system tract period, which resulted in that deep- water gravity flow regressively deposited within the 3rd order sequences and progressively developed within each single 4th order sequence during the period. The relatively stable tectonic condition makes Chunxia sub- submember featured with retrogradation to aggradation in the 3rd order sequence and steady progradation in the 4th order sequence. The “fluid transformation” caused by “flow separation” during the transportation process of deep water gravity flow could better explain the differential distribution patterns of different deep- water gravity flow deposition from the proximal to distal area as well as the formation of the “distal sandy debris deposition”.
