| 摘 要： | 天山北侧前陆盆地即准噶尔盆地 ,该盆地南缘存在严重的超高压异常现象。异常高压的成因主要为“沉积型”和“构造型”两种造压机制 ,其形成演化分为拉张沉积期静水压力阶段、沉积造压及压力封存箱形成阶段和压力封存箱挤压增压阶段。利用有限元模拟法计算研究区主应力值 ,建立主应力值与异常压力系数的匹配关系 ,预测准噶尔南缘紫泥泉子组异常压力平面分布特征。

| Abstract: | The foreland basin to the north edge of Tianshan refers to Junggar Basin. There exists the abnormally high pressure in the south edge. The genesis of abnormal high pressure has two types, namely the sedimentary type and tectonic type. The evolution of the abnormal high pressure experienced three stages, namely the hydrostatic pressure stage in the depositional period, the abnormal pressure compartment formation stage, and the pressure rising stage in the pressure compartment under extrusion. Through computing the principal stress in the study area by the finite element modeling, the match relation between the principal stress and the abnormal high pressure coefficient is used to predict the plane distribution of the abnormal high pressure of Ziniquanzi Formation in the south edge of Junggar Basin. |
