Abstract: The stratigraphic-lithological hydrocarbon accumulation zone is inferred to a group of plays formed by changes of lithofacies, lithology and strata. It controls the formation and distribution of stratigraphic-lithological reservoirs with the same geological backgrounds and genesis. The stratigraphic-lithological hydrocarbon reservoir is the main exploration object in the hydrocarbon accumulation zone. The clear target beds and excellent description methods are necessary. The stratigraphic-lithological hydrocarbon accumulation zone was divided into lithological change zone and stratigraphic change zone according to the main controlling factors and then divided into front facies zone, fan near shore, river channel, overlap zone and unconformity zone according to the deposit facies type and stratigraphic contact relation. The formation conditions and characteristics of the different zones were analyzed.

Key words: stratigraphic-lithological hydrocarbon accumulation zone, stratigraphic-lithological reservoir, front facies zone, fan near shore, river channel, overlap zone, unconformity zone

摘要： 岩性地层型油气聚集区带是指一组受岩相、岩性或地层变化影响而形成的成藏组合,控制了具有相似地质背景和成因类型的岩性地层油气藏的形成与分布。岩性地层型油气聚集区带以岩性地层油气藏为主要勘探对象,具有明确的勘探目的层系,对描述手段的要求更高。根据成因主控因素,将岩性地层型油气聚集区带划分为岩性变化带和地层变化带两大类,并进一步按照沉积相类型和地层接触关系划分为前缘带、近岸扇体、河道、超覆带、不整合带5种主要的区带类型。对不同类型区带的基本特征和控藏规律进行了讨论。
