摘要

摘要: 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2010-2015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18×10⁴～20×10⁴t;天然气年产量可能达到1 000×10⁸m³以上.

Abstract: The Nanpu Sag,which is located in the northern part of the Huanghua Depression in the Bohaiwan Basin,is a hydrocarbon-bearing sag developed since the Cenozoic.It went through faulting and depression two evolutionary stages.The denudation restoration showed that the infilling of the basin had "e pisodic" subsidence features.By studing on magmatic activities and temperature-pressure field evolution as well as their relations to subsidence ratio,the time sequence of magmatic activities in basin evolution and its coupling relation to sedimentation were determined,and the relationship between magmatic activities and the ancient temperature-pressure field evolution of the basin was distinguished.This will provide new and important research thought and means for the recognition of hydrocarbon accumulation conditions.
