陆东凹陷具有良好源岩层,储层以次生溶孔为主,具中低孔、细喉、低渗的特征,盖层条件良好,圈闭多与断层有关,均定型于青山口组沉积前的燕山早幕运动,油气纵向运移是浅部阜新组成藏的关键,侧向运移成藏是九佛堂组油气富集的显著特点。断层对区内油气成藏有关键性作用,生烃中心周边大型沉积体系前缘地带的圈闭发育区和中央断裂构造带是油气的主要富集区
The Luodong Sag has a good source rock formation. The reservoirs are dominated by secondary dissolved pores with medium- to low-porosity, fine-throat and low-permeability features. The cap rocks are well-formed and the traps are mostly related to faults, and are all characterized by deposition in the Qingshankou Formation Former Yanshanian Early Movement and Longitudinal Hydrocarbon Migration are the key to the formation of the Fuxin Formation in the shallow part. Lateral migration and accumulation are the distinctive characteristics of oil and gas accumulation in the Jiufotang Formation. Faults play a key role in hydrocarbon accumulation in the area. The trapped development zone and central fault zone of the major sedimentary system surrounding the hydrocarbon generation center are the major enrichment areas for oil and gas
