| 摘 要： | 在构造演化分析的基础上对黄骅坳陷的新生代构造应力场演化进行了光弹实验模型,认为黄骅坳陷新生代最大主应力方向具有从NNE向挤压向NE、NEE向转变的右旋特征,构造应力场方向的右旋转变控制着断层的活动与坳陷的形成,使得早期(孔店期、沙河街期)以引张形式活动的断裂到晚期(东营期及其以后)逐渐转变为以走滑形式活动,促成了多期构造叠加,形成了多种圈闭类型,为油气成藏富集创造了有利条件。

| Abstract: | Based on the analysis of tectonic evolution,photoelastic experimental modelling is operated on the evolution of Cenozoic tectonic stress field in Huanghua depression.It is considered that there is a dextral rotation from NNE -to NE、NEE trend on the evolution of Cenozoic tectonic stress direction in Huanghua depression.It controls the activity of the faults and the formation of the depression,makes the fault activity transforming from extension in early stage (Kongdian and Shahejie Formation) to strike-slip in later stage(Dongying Formation and after it),facilitates multistage structure superimposed and formed various type traps.All those make an advantage for the hydrocarbon accumulation. |
