摘要
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－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。
Bohai petroleum province lies in the central part of Bohai bay basin,covering an area about 51,000 square kilometers,and concluding 12 oil-generated depressions. In the view of tectonics -sedimentary and evolution history of source rocks,these 12 depressions could be classified into 4 types , i. econtinuous deep-burial type, pulse deep-burial type, continuous middle-burial type, and early slow and later fast middle-burial type. There are 4 series of source rocks in the area .concluding Es4,Es3,Es1 of Shahejie formation and lower Dongying formation,the resource amount is about 10 billion tons. This material has the capability to build and stablize 10 million tons petroleum output per year. According to the surface and subsurface conditions in Bohai Sea,the four exploration-developnent systems,i.e. ,Liaobei,Liaozhong,Bozhong and Boxi'nan are designed in order to increase production and stabilize ontput.
