摘　　要：作为江陵凹陷油气勘探的领域之一,白垩系在许多关键问题上还存在分歧和争议,白垩系的成藏主控因素是争论的焦点问题之一。笔者在回顾江陵凹陷的勘探历程和总结归纳前人成果认识基础上,根据SK8-16最新的钻探成果发现,白垩系成藏主控因素①烃源-断层双控是基础;②储层的发育程度影响油气的富集;③后期保存条件是关键;④优越的成藏模式和成藏配置关系是油气突破的重点。The controlling factors for the hydrocarbon accumulation in the Cretaceous strata in the Jiangling depression have long been one of the controversial problems. The new results of exploration obtained from the SK8- 16 well has disclosed that the main controlling factors for the hydrocarbon accumulation in the Cretaceous strata in the Jiangling depression include ： （ 1 ） double controls of hydrocarbon sources and faults ; （2） development of reservoir rocks; （3） paulopost conditions of preservation, and （4） favourable models and plays.
