Seismoturbidite is a common kind of petroliferous reservoir in the continental rift lacustrine basin. According to the flume experiment, the forming process of seismoturbidite is simulated. The results show that there are two kinds of slumping in delta front under seism and three kinds of seismoturbidites: liquefied turbidites, secondary slumping turbidites and secondary overlapped turbidites can be formed. They are widely developed in delta front, and they usually overlap vertically and occur in belts regionally. The secondary slumping turbidites are mainly developed in the deep sag below the bed form break and can form one of the most favorable subtle petroleum reservoirs in the rift lacustrine basin. The factors controlling the distribution of seismoturbidites mainly include the sedimentary characteristics of delta front, the intensity of seism and the depositional bed form of delta front.
