On the basis of seismic data and regionally electromagnetic sounding data in zhanhe fault depression and Jiayin fault depression,combining the drilling data of Jia-D1 well and Jia-D2 well,beginning from geologically constructional character of the basin and its circumambience,integrating the up-to-dade theories of sequence stratigraphy home and abroad,the thesis firsthy indudes the constructional pattern,the process of constructional evolvement,the process of sedimentary evolvement,the character of lava\'s groming and the geological character of oil\'s producing,depositing and coveringThe tectonic framwork of Zhanhe fault depression is two sags and one uplift , the tectonic framwork of Jiayin fault depression is three sags and two uplifts, the strikes of structures are the north north-east, early it is a fault depressions and later becomes a depression s so this basin is faulted depressed basins.

涉及隐私，隐去***论文是以沾河断陷、嘉荫断陷地震资料及区域电磁测深资料为基础，结合嘉D1、嘉D2井钻井资料，从盆地及其周边的地质构造特征出发，结合国内、外最新层序地层学理论，首次总结了沾河—嘉荫断陷构造格式、构造演化过程、沉积演化过程、火山岩发育特征和生储盖石油地质特征。沾河断陷表现为两凸夹一凹的构造格式，嘉荫断陷表现为三凸夹两凹，构造走向均为近北北东向，早期表现为断陷特征，晚期表现为坳陷特征，为断、坳复合型盆地。

Taking the plate tectonics as leading theories, combining outcrop, seismic techniques, drilling and logging datum, inter-verifing manifold researching methods, The paper has amply researched the region. discussed the coupling relation of basin-mountain and the geodynamics system; analyzed geologic tectonic characteristics of the basin; confirmed superposed alteration in Mesozoic of the basin; recompartmentalized tectonic units of the researching region and the basin; studied the tectonic evolution of the basin since Mesozoic; ascertained four large tectonic layers and five tectonic evolution process stages in different ways of formation and tectonic alteration; established different tectonic stages、compages、models and sedimentary filled processes, based on the organic geochemistry and oil-gas geologic characteristics in middle Cenozoic of the basin, the conclusions have been summarized in the paper, such as:The primary source rock in lower Permian and subordinate source rock in upper Triassic are developed in the region with better quality, and secondary hydrocarbon is possible; The bearing system which is comparted by three large tectonic layers and two unconformity surfaces formed in Palaeozoic、upper Palaeozoic to Triassic and Cenozoic developing in the region, compounded with reservoirs of different lithology is developed in the region, while the property of tectonic fracture reservoir is better; Based on the analyzing petroleum accumulation elements and preserving conditions, the deep depressing belt in the north of Luoyang depression、Shiling-Yiyang folded fault belt in Yiyang depression and wide anticline belt in Yichuan depression are advantageous petroliferous region, Zhaizhen anticline in Luoyang depression and Shimen wide anticline on footwall of overthrust in Yichuan depression are optimum tectonic traps.
