摘要
///A study of lithologic character, sedimentary structure, fossils, sequence and sedimentary facies indicates that the sandstone bed 22 of the Triassic Yanchang Formation in the Xifeng Oilfield is a normal delta deposit. It may be divided into 4 microfacies such as distributary channel, natural levee, interdistributary bay and crevasse splay.
