南堡凹陷区域构造上位于渤海湾盆地黄骅坳陷北部 ,是一个新生代开始发育的含油气凹陷 ,经历了断陷期和坳陷期两个演化阶段。回剥分析表明 ,盆地充填具有“幕式”沉降特征。文中通过对岩浆活动、温压场演化及其与沉降速率之间关系的研究 ,厘定了岩浆活动在盆地演化中的时间序次及其与沉积作用的耦合关系 ,识别出岩浆活动与盆地古温压场演化之间的成生关系 ,并为油气成藏条件的再认识提供了重要而新颖的研究思路与途径。预计 2 0 10— 2 0 15年新疆和近海将建成特大型油气区 ,加上松辽、渤海湾、鄂尔多斯、川—渝、柴达木等 ,全国石油年产量可能逐步达到 18× 10 4～ 2 0× 10 4t ;天然气年产量可能达到 10 0 0× 10 8m3 以上。
The Nanpu Sag is structurally located in the northern part of the Huanghua Depression in the Bohai Bay Basin. It is a hydrocarbon-bearing depression developed during the Cenozoic. It experienced two stages of evolution and fault depression. Back-stripping analysis shows that basin filling has “curtain” sedimentation characteristics. By studying the relationship between magmatism, the evolution of temperature and pressure field and its sedimentation rate, time series of magmatism in the evolution of the basin and their coupling relationship with sedimentation are determined. The relationship between magmatism and paleo-temperature Pressure field evolution between the birth and the relationship between the formation of oil and gas for the re-understanding of the conditions provided an important and innovative research ideas and ways. It is estimated that extra large oil and gas areas will be built in Xinjiang and offshore areas in 2010-2015. Combined with Songliao, Bohai Bay, Erdos, Sichuan-Chongqing and Qaidam etc., annual oil production in the country may gradually reach 18 × 10 4 ~ 2 0 × 10 4t; annual output of natural gas may reach 10 0 × 10 8m3 above.
