Lithofacies palegeography is depicted in the framework, and the result shows that evolution of lithofacies palegeography is mainly affected by tectonic movement, and distribution range of delta front subfacies becomes larger, while delta plain becomes smaller, and the favorable sedimentary microfacies for reservoir development is distributary channel
