摘要:

剪切带带内某些次级应变与现有走滑应变椭圆的7类应变要素(PDZ,R,R′,P,T,Y破裂及局部挤压变形)难以准确对应。为解决这一问题,以右行走滑为例,通过理论推导与试验模拟,深入研究次级应变表现出的应变性质,并据此提出包含所有应变性质组合(8类)的完全分类模型。该模型包括4个单纯性质的应变带(纯右行走滑、纯左行走滑、纯挤压和纯伸展应变带)和4个复合性质的应变区(伸展兼右行走滑、伸展兼左行走滑、挤压兼左行走滑和挤压兼右行走滑应变区)。复合性质应变区中,越靠近单纯性质方向的应变,产生相应性质的动力就越强。该模型在理论上论证了传统走滑模型的合理性并弥补其空缺部分。同时,举3个渤海的研究实例说明该模型改进后的应用: 莱州湾凹陷东北洼挤压与伸展作用共控成圈,说明走滑带内的挤压与伸展应力场同步持续、相互垂直的时空关系,以及二者的统一而非矛盾的辩证关系; 渤海走滑转换带的研究成果,说明走滑带内伸展或挤压型转换带的应变走向规律; 渤海某潜山油田的有效裂缝研究成果,说明有效裂缝的走向与现今走滑应力场中的伸展应变区对应的关系。

Abstract:

For some strain in the strike slip zone is difficult to be determined accurately in the classification scheme of the 7 elements of the ellipse of the strike slip strain ellipse (PDZ, R, R', P, T, Y and local contraction), the properties of the strain elements in all directions in the strained ellipse were reunderstood by analyzing the causal relationship between the mechanical state and the strain properties in a certain direction. A new model of the Riedel shear system was proposed, which contained 4 pure strain zones (pure right walk slip, pure left walking slip, pure extrusion, pure Stretch Strain Zone) and 4 complex strain zones (both stretching and right walking, both stretching and left walking, both extrusion and left walking, both extrusion and right walking slip strain zone). The closer the crack was to the direction of a single strain band, the stronger the corresponding property. The model included all the elements of the traditional model and made up for its vacancy. It proved the rationality of the left (right) row left (right) order and the double tectonic belt rule. At the same time, three research examples of Bohai Sea were cited to illustrate the application of the model: (1) The synchronous and perpendicular spatial-temporal relationship between compressive and extensional stress fields in strike-slip zones, as well as the unified but not contradictory dialectical relationship between them, were illustrated through the example of the co-controlled cycle formation of northeastern depression in Laizhou Bay Depression; (2) The Bohai Sea walk was enumerated. The research results of the slip transition zone illustrated the strain trend law of the extensional or compressive transition zone in the strike-slip zone; (3) The relationship between the strike of the effective fracture and the extensional strain zone in the present strike-slip stress field was illustrated by giving an example of the effective fracture research results of a buried hill structure in the Bohai Sea.

Key words: Strike slip strain ellipse model    Theoretical derivation    Experimental simulation    Strain factor    Complete classification.
