摘　　要：焉耆盆地博湖坳陷侏罗系烃源岩生成的油气主要通过"层状运移"和"网状运移"2种模式进行运移,油气的聚集过程遵循"差异聚集"原理,油气的调整过程存在"纵向调整"和"横向调整"2种模式,已聚集的油气通过"暴露条件"和"埋藏条件"2种模式散失。该区下一步油气勘探的重点领域应转向"受构造运动影响较小、后期油气保存条件较好"的岩性圈闭油气藏。The migration of oil and gas generated from Jurassic source rocks in Bohu depression of Yanqi basin mainly depends on two modes of layered migration and reticulated migration.The hydrocarbon accumulation process follows the ＂differential accumulation＂ principle,and the oil-gas adjustment modes appear in ＂vertical adjustment＂ and ＂horizontal adjustment＂.Also,the accumulated oil and gas are lost by ＂exposure condition＂ and ＂buried condition＂.This paper suggests that the key area for further petroleum exploration in Bohu depressions should turn to the lithological reservoirs with ＂less tectonic movement effects and better oil-gas preservation conditions in the late stage＂.
