向斜轴部中和面以下层段油气勘探

Exploration for Oil and Gas in Intervals under Neutral Plane at Axial Part

背斜、向斜褶皱构造是沉积盆地的基本形变,中和面也是地层变形中的重要界面,在传统的石油地质理论中,一直忽视了这一重要界面。中和面的上、下层位在背斜、向斜构造中应力性质不同,影响着储层的物性,也与油气的聚散有关。向斜轴部中和面以下层段与背斜轴部中和面以上层段一样,都是张性区域,也是油气的有利聚集区。结合区域构造运动和断层组合分析,寻找向斜轴部中和面以下层段油气藏,是未来油气勘探的新领域。

Anticlines and synclines are the basic deformation forms of sedimentary basins,as well as neutral planes are the important interface of strata deformation.But the neutral plane is paid no attention in the traditional petroleum geological theory.The stress properties of the upper horizon are different from the lower horizon in anticlines and synelines,which exerting effect on reservoir physical properties.Besides it is related to oil and gas accumulation.The intervals under the neutral plane at the axial par...
