Structural characteristics and formation mechanism in Dongxin Oilfield, Jiyang Depression, Bohai Bay Basin: insights from physical simulation
-
摘要: 通过几何学特征、运动学特征、成因机制分析及构造物理模拟实验,对济阳坳陷东辛油田断裂构造特征及成因机制进行了研究。研究区构造形态自东向西逐渐趋于复杂,平面上,东部辛镇构造以平行式组合为主,整体呈现"单一型"构造样式,中部过渡带以平行式、斜交式组合为主,整体呈现"网格型"构造样式,西部东营构造以雁列式、帚状组合为主,整体呈现"复杂型"构造样式;剖面上,区内主要发育负花状、反"Y"字形、阶梯状、地堑、地垒等5种断裂组合样式,整体呈现典型的"包心菜式"复杂断裂系统。构造物理模拟实验结果与实际地质情况拟合程度较高,实验结果进一步证实,东辛地区断裂构造组合样式是新生代伸展-走滑应力场与岩浆底劈作用叠加的产物,其根本动力来源于新生代NW-SE向伸展应力场、郯庐断裂带的右行走滑及岩浆等塑性物质上涌。Abstract: The structural characteristics and formation mechanism of faults in the Dongxin Oilfield of the Jiyang Depression were systematically studied through the analyses of geometric and kinematic characteristics, genetic mechanism and structural physical simulation experiments. The structural form in the study area gradually trends toward complexity from east to west. The Xinzhen structural belt in the east is mainly composed of parallel structures, presenting a simple structural style. The transitional belt in the middle is composed of parallel and oblique structures, presenting a grid structural style. The Dongying structural belt in the west is composed of en echelon and broom-like structures, presenting a complex structural style. Vertically, there are five main fault combination styles in this region, including negative flower-like, inverse "Y" shaped, step-like, graben and horst, showing a typical "cabbage" complex fault system. Physical simulation results fit the actual geological conditions well. The experimental results further confirm that the fault structural assemblage pattern in the Dongxin area is the product of the superposition of Cenozoic extensional-strike-slip stress field and magmatic bottom rifting. Its fundamental driving force is derived from the NW-SE extensional stress field, the right strike-slip of the Tanlu fault zone and the upwelling of plastic materials such as magma.
