摘要
The sedimentary characteristics are described,on the basis of cores and well logs, with the emphasis on the division of the sedimentary facies in the lower submember of the 2nd member of the Shahejie Formation in the Wennan oilfield. The sediments in this submember are assigned to the ephemeral lacustrine-delta deposits laid down under the dry climatic conditions. Finally, the lake basin was subjected to the collapse till the end of the deposition of the 1st sand sets.
