Integrative description on turbidity sand body of Es_3 in Bonan oilfield,Jiyang Depression

Turbidite fan body lithologic deposit developed easily in continental lacustrine basin which is small sag and close by source area.Turbidity sand bodies developed in Es_3 of Lower Tertiary in the southern basin of Jiyang depression. The turbidity fan bodies can be divided into outer turbidity fan and fluxoturbidite.This paper discusses the sedimentary features, distribution and accumulation pattern of the fluxoturbidite of Es_3 in Bonan sag,introduced that the Turbidite fan bodies were described by geology and geophysical technologies.
