In the Bohai Sea, structural oil and gas reservoirs account for the highest proportion of proven oil and gas reserves, followed by composite oil and gas reservoirs. In large and medium-sized oil and gas fields, which account for one-third of the total oil and gas fields, the proven oil and gas reserves account for 83% of the total reserves. Low uplift, middle sag uplift, and uplift structural belts have the most proven oil and gas reserves. Vertically, more than half of the proven oil and gas reserves are concentrated in the Neogene strata. More than 90% of the proven oil reserves and 85% of the proven gas reserves are distributed in shallow-middle reservoirs less than 3,000 M. The distribution of oil and gas in the Bohai Sea is the result of the interaction of a series of geological processes, such as source rocks, sedimentary systems, tectonic and fault systems development, and evolution. Oil and gas migrate and accumulate in short distance around hydrocarbon-rich sags; favorable sedimentary facies belts, high-quality lithofacies, and good physical properties determine the development of high-quality reservoirs in the Bohai Sea.
