摘要
Turbidite is widely developed in the bathal-abysmal lake subfacies of Chang-6 oil reservoir for-mation in the southwestern Ordos Basin. This paper summarizes characteristics of the turbitite with respect of its sedimenta-ry structure, structure of sand body, electric property and seismic reflection. The results show two obvious turbi-dire zones varied in spacial extension and and size of sand body： 1) Baibao-Huachi zone in Huaqing area whose turbitite was deposited on gentle slope with larger size of layeroid sand body in plan; and 2) Zhengning-Hesui zone whose turbidite deposited on steep slope with smaller size of sand body in flower and fan shape in plan.
