Study on Reef Growth Environment and Distribution Characteristic in Deepwater Area of the Qiongdongnan Basin

As an important hydrocarbon reservoir, reefs have great potential in oil exploration. Qiongdongnan basin is located in the northern continental margin of South China Sea, with favorable environment for reef growth and carbonate development during the evolution process. The south deepwater area of Qiongdongnan Basin is far away from the provenance, and many structural highs have developed, which was favorable for reef development. Through seismic data interpretation, it is believed that different scale reefs have developed in the southern deepwater area of Qiongdongnan Basin. In addition, these reefs have great hydrocarbon potential, and the development reefs can be correlated well with the tectonic evolutionary stages.
