Under the guidance of the spirit of reform and opening up in recent years, China’s oil development has moved toward a new era of “full bloom.” “Moving from land to sea” is a notable mark in this new era.

Among them, the depth of 200 meters in the continental shelf area of ​​about 1.3 million square kilometers. According to the data of geophysical surveys such as artificial seismic method, gravity method and magnetic force method, it shows that there is a rich sea beneath this vast continental shelf
