摘要
海南福山凹陷构造格架与断陷样式受基底大断裂控制,发育深、浅2套产状和活动特征不同的断裂系统。前者有利于对油气的遮挡和圈闭成藏,后者则促进导致了油气的散失和油气藏的破坏。海南福山凹陷发育2大类、4种成因类型、8种活动模式的断裂,基底大断裂对海南福山凹陷烃源岩的展布、圈闭的形成、油气的运聚成藏均有重要的控制作用。凹陷内发育反向断层遮挡和顺向断层疏导2大类共6种油气运聚成藏模式。
The tectonic framework and rifting patterns of the Fushan Depressron in Hainan were controlled by basement major faults. There developed deep and shallow two wets of fault systems with different occurrence and active features. The former was advantageous to hydrocarbon screening and pool formation, and the later resulted in the dispersion of oil and gas and the destruction of hydrocarbon pools. In the Fushan Depression of Hainan, faults of two kinds, four genetic types and eight active models were developed, and basement major faults had important controlling roles to the distribution of bydrocarbon source rocks, the formation of traps and the migration and accumulation of oil and gas. Also, reverse fault screening and consequent fault dredging two kinds including six types of pool-forming models for hydrocarbon migration and accumulation were developed.
