More than 40 years have been passed since exploration and development of oil‐gas began in the Bohai Bay Basin. Though we have faced with many difficulties during our exploration, exciting discoveries in petroleum‐rich sags have been made in recent years. Studies show that the petroleum‐rich sags are characterized by multiple sets of oil‐gas accumulation in the pre‐Eogene to Neogene strata in profile and large‐area connection or superimposition of oil‐gas reservoirs in different strata. Therefore, petroleum‐rich sags continue to be a focus of future oil‐gas exploration in the Bohai Bay Basin. There is still a great potential of petroleum resources. Inshore and offshore areas, onshore stratigraphic reservoirs, high‐precision exploration in old oilfields, reservoirs inside buried hills, and volcanic reservoirs will contribute a lot in increasing the annual oil‐gas production and reserves in the basin.
