摘　　要：准噶尔盆地腹部永进地区位于车莫古隆起南翼,受车莫古隆起的控制,在白垩—侏罗系不整合面之下广泛发育地层、地层—岩性型隐蔽圈闭,研究此类油气藏形成的主控因素十分必要。对该区隐蔽油气藏成藏主控因素研究的结果认为:车莫古隆起对油气藏的聚集和调整以及优质高效储层的发育都起着关键的控制作用;断层、砂体、不整合面构成了油气立体输导格架,控制着该区隐蔽油气藏的分布。在以上认识的基础上,以沉积模式、成藏模式为指导,综合应用地震属性分析、测井约束反演等技术手段,确定了不整合面下地层剥蚀线的展布范围、有利储集相带和砂体的展布规律。Yongjin area in the central Junggar basin is located on the south limb of Chemo paleohigh. Stratigraphic and stratigraphic-lithologic subtle traps are extensively developed below the Cretaceous-Jurassic unconformity due to the control of Chemo paleohigh. Therefore, it is very important to study the main factors controlling the formation of these hydrocarbon reservoirs. The study reveals that Chemo paleohigh played a key role in controlling the accumulation and adjustment of hydrocarbons and the development of reservoirs with high quality and efficiency, and the stereo pathway framework composed of faults, sandbodies and unconformities controls the distribution of the subtle reservoirs in the study area. Based on these understandings, the distribution area of erosional line of the formations underlying unconformities and the distribution patterns of favorable reservoir facies belts and sandbodies are defined by integrating seismic attribute analysis and log-constrained inversion and under the guidance of depositional models and hydrocarbon pooling models.
