Abstract
The authors observe the cores of Well N30 and Well N43, which belong to the intermediate section of Member 3 of Shahejie Formation in the Niuzhuang depression, research a lot of data on log, grain, porosity, rate of percolation and tectonic background, and think that there are two kinds of turbidite fans: the deep-water turbidite fan and creeping turbidite fan in the front of the delta . Then, the authors sum up the characters of microfacies and sedimentation, discuss the relation between deep-water turbidite fan and creeping turbidite fan in the front of delta, and at last propose their evolution models.
