赵县背斜位于冀中坳陷晋县凹陷，是富集油气的底辟构造，为多种原油性质、多种类型油气藏的复式油气藏集合体。该背斜形成的物质基础是存在早第三纪早期发育的比较稳定的膏岩和膏泥岩塑性地层，其形成机制是塑性地层底辟拱升和区域性右旋拉张构造应力场作用下发生的滑脱拉张。该背斜核部及北翼以中部生油洼槽为烃源区，因主要油源层为盐湖相沉积，成烃机理为沥青热降解，所以成为重质稠油聚集区；背斜南翼以南部生油洼槽为油源区，其主要油源岩属于淡水—微咸化湖沉积，成烃机理为干酪根热降解，因此成为中—轻质稀油聚集区；东翼以自生自储油气源为主，因其油源岩发育于两种沉积环境的过渡区，两种成烃机理均可形成原油，故成为中质常规油聚集区。在分析成藏机理和油气分布规律的基础上，提出下步勘探的３个重点方向：①尚未钻探的背斜北翼地堑构造，主要寻找Ｅｓ３—Ｅｋ１的构造油藏；②背斜南翼构造低部位，主要寻找Ｅｓ３、Ｅｓ４—Ｅｋ１的岩性油藏、地层超覆油藏等非背斜油藏；③背斜东翼构造高部位，主要寻找Ｅｓ４—Ｅｋ１中下部的构造油藏和非背斜油藏。图４参３（梁大新摘）
The Zhaoxian anticline is located in the Jinxian depression in the Jizhong Depression. It is a diapiric structure enriched in oil and gas, and is a multi-type reservoir assemblage of various types of crude oil and various types of oil and gas reservoirs. The material basis of this anticline is the relatively stable gypsum and plaster plastic strata that exist in early Early Tertiary, and their formation mechanism is caused by the plastic strata diapir arches and the regional tectonic tensile stress Slip of the stretch. The central part of the anticline and the north wing are hydrocarbon source areas in the middle oil-producing depression. Since the main oil source is salt-lake facies, the hydrocarbon-forming mechanism is thermal degradation of asphalt, so it becomes a heavy heavy oil gathering area. The south anticline The southern source depression is the oil source area, and the major source rocks belong to the freshwater-brackish lake. The hydrocarbon generation mechanism is kerogen thermal degradation, so it becomes medium-light and thin oil accumulation area. Because of its oil source rocks developed in the transitional zone between the two depositional environments, both hydrocarbon generation mechanisms can form crude oil, so it becomes the normal oil accumulation zone of the medium. Based on the analysis of the mechanism of hydrocarbon accumulation and the laws of oil and gas distribution, the following three key directions for further exploration are proposed: (1) The un-drilled anticline north wing graben structure is mainly for structural reservoirs of Es3-Ek1; (2) The low-lying structures are mainly located in Es3, Es4-Ek1 lithologic reservoirs and stratigraphic overlying reservoirs and other non-anticlinal reservoirs. The high anticlinal parts of the eastern wing are mainly located in the structural reservoirs in the middle and lower parts of Es4-Ek1 and Non-anticlinal reservoir.
