苏北盆地金湖凹陷内压扭性构造的地震反射
|
摘要
在郯庐断裂从左旋到右旋的演化过程中,下扬子地区苏北盆地中各凹陷基本上都形成了弧形或雁行式排列的压扭性构造带,这些压扭构造带是苏北盆地各凹陷中构造圈闭和油气最发育的部位,目前基本上都形成了油气田。通过多年的地震勘探工作的研究成果表明金湖凹陷中具有典型的压扭性构造。以三维地震资料解释为基础分析了金湖凹陷压扭性构造的展布特征,并揭示其与油气发育和圈闭的关系,确定圈闭发育区。
During the transition of the Tan-Lu fault from sinistral to right-lateral strike-slipping, echelon or arc compresso-shear structural belts were generally developed in some sags of the Subei basin in the lower Yangtze region. These structural belts resulting from compresso-shearing are the most developed area of structural traps and also the field of petroleum accumulation. Seismic exploration in recent years has revealed that typical compresso-shear structures exist in Jinhu sag. In this paper, the distribution characteristics and petroleum prospects of compresso-shear structures in Jinhu sag are interpreted and analyzed according to 3-D seismic reflection data,the relationship between the trap and the development of petroleum is discussed, and the development area of trap is delineated.
