Abstract

Based on the data of well logging and petrology characteristics,sedimentary structures of the cores,the sedimentary environment of Chang3-6 oil formations of Triassic Yanchang Formation in Huanxian area was studied.The results show that Chang 6 develops front-delta facies and turbidite fan,Chang 4+5 and Chang 3 develop front-delta facies.
