渤海油区位于渤海湾盆地中部,探区面积约51000km~(2),发育了12个生油凹陷.据构造一沉积及烃源岩演化史,可将这12个凹陷分为持续深埋型、脉动深埋型、持续中埋型和先缓后速中埋型等4类.渤海油区发育沙河街组四、三、一段及东营组下段等4套烃源岩,资源量约100亿t,具备今后实现稳产1000万t石油的物质基础.根据渤海的地下、地面条件,规划辽北、辽中、渤中和渤西南4个勘探开发体系,实现上产和稳产.
The Bohai oil zone is located in the middle of the Bohai Bay Basin with an exploration area of about 51000km 2 and 12 oil-gas depressions.According to the tectono-sediments and the evolution history of source rocks, the 12 depressions can be divided into continuous deep buried , Pulsation deep burial, continuous buried burial type and the first slow afterburied burial type 4. Bohai oil zone development Shahejie Formation four, three, a and Dongying Formation, the lower reaches of four sets of source rocks, resources, about 10000000000 t and have the material basis for the steady production of 10 million tons of oil in the future.According to the subsurface and ground conditions in the Bohai Sea, four exploration and development systems in northern Liaoning, Liaozhong, Bozhong and Bohai South are planned to achieve high production and stable production.
