Abstract

Based on the regional geologic settings, combined with the analysis of sedimentary sequence, core features and well logging data, this paper studied the sedimentary system, evolutionary process and reservoir characteristics of Beisantai swell, and predicted the favorable range zone. The result shows that from the northeast to southwest of the study area, there successively developed braided delta front subfacies,delta front subfacies and shallow lake subfacies, and the principal source is mainly from the Kelameili mountain in the northeast. The main controlling factors of the sedimentary facies distribution are tectonic uplift and subsidence, lake level changes and sediment supply. According to the reservoir physical properties, the study area belongs to low permeability and low porosity type Ⅲ reservoir, and high
quality reservoir facies belts are mainly developed in underwater distributary channel.
