摘　　要：以地质力学理论为指导,通过开展塔里木、准噶尔—吐哈、走廊、鄂尔多斯、四川、松辽、渤海湾等8个(地区)构造体系控油作用研究,深刻认识到油气田分布主要受各类低序次扭动构造体系的控制,在此基础上,发展和建立了五类低序次扭动构造体系控油模式,包括帚状构造体系、旋扭构造体系、雁列构造体系、入字型构造体系和反"S"型构造体系。文章分别以具体典型实例系统概述了其各类低序次构造体系的形成特征、油气成藏条件及分布规律,认为构造体系的形成受不同构造环境和应力场控制;不同低序次扭动构造控制油气田分布规律各异。这些控油模式的建立对当前和今后油气勘探和油气田发现有重要指导意义。Guided by the theory of geomechanics, the oil-control effect of 8 （regional） structural systems, including Tarim, Junggar-Tuha, Corridor Area, Ordos, Sichuan, Songliao and Bohai gulf are studied. It is deeply recognized that the distribution of oil and gas fields is mainly controlled by various subordinate shear structural systems. On this basis, the oil control model of five kinds subordinate shear structural systems are developed and established, including the broom structural system, shear structural system, en echelon structural system, λ-type structural system and reverse S-type structural system. The formation characteristics, hydrocarbon accumulation conditions and distribution rules of various subordinate shear structural systems are summarized with typical examples. It is believed that the formation of different structural system is controlled by different structural environments and stress field. The distribution rules of oil and gas fields are different under the control of different subordinate shear structures. The establishment of these oil-control models is of great significance to current and future oil and gas exploration and discovery.
