石港断裂带紧邻三河生油次凹，资源潜力较大，但构造复杂制约了勘探认识。近年来随着钻井资料的不断积累和地震资料品质的改善，为进一步认识该区构造特征和油气富集规律创造了条件。从油藏特征及油气运移分析入手，建立了石港断裂带油气运聚模式。通过对断裂体系、圈闭及油气成藏三者之间的关系研究，认为该区断层控藏作用主要体现在三方面：断裂体系对圈闭的控制、断层侧向封堵性对油气富集的控制以及断层垂向沟通性对油气分布层位的控制。

Shigang fault zone is close to Sanhe source sub -depression with great resource potential,however,the ex-ploration is restricted by the complex structure.In recent years,the continuous accumulation of drilling data and the im-provement of seismic data quality both create the conditions for the further study on the area structural feature and hydro-carbon enrichment regulation.Starting from the analysis on the reservoir characteristic and the oil -gas migration,the mi-gration and accumulation model of Shigang fault zone has been established in this essay.Based on the relationship among fault system,trap and accumulation,it was concluded that the control effects of faults on reservoirs mainly included the fol-lowing three aspects:the control of fault system on traps,the lateral sealing property of fault on the accumulation degree of oil and gas,and the vertical migrating property of fault on the oil -gas distribution layer.
