海塔盆地中部断陷带反转构造特征及其对油气的控制
摘要
为研究海塔盆地中部断陷带反转构造的类型、分布、形成机制、与油气藏的关系及成藏模式和控藏特征,分析地震、油气藏开发及地球化学等资料.结果表明:伊敏组晚期,海塔盆地中部断陷带在近东西向压扭应力场作用下发生大规模反转,形成断层型、褶皱型和混合型3类5个亚类反转构造,并与上部含油气系统的大二段次生油气藏具有良好耦合关系.大二段次生油气藏为反转期原生油气藏沿主干反转断裂向上调整形成,以南一中段及下段烃源岩形成的原生油气藏为源,以大二段砂岩为储层,以伊敏组泥岩为盖层,以主反转断层为疏导为成藏模式;该次生油气藏的形成与反转程度密切相关,主要形成于反转程度较弱的塔南凹陷隐伏断展型反转构造发育的区域,北北东向的隐伏断展型反转构造圈闭是寻找该类次生油气藏的首选目标.
Haita basin is Cenozoic rift basins.Ministry rift includes four sags.In order to identify its type,distribution,formation mechanism,relationship with reservoir and accumulation mode,based on the systematic analysis of the middle rift zone of Hailaer-Tamuchage basin with seismic profiles and exploration and development on the basis of geological data,we put foreward some ideas that under the action of North West compression stress field the middle rift zone of Hailaer-Tamuchage basin had developed three large types and five small types of inversion tectonics,they are fault,fold,hybrid inversion tectonics.Inversion tectonics within the study area and the secondary reservoirs of Daer layer section coupled with good relations.The analysis shows that this kind of reservoir is inversion period primary oil reservoir which adjusted upward to form along the main inversion fault.Inversion structures in the region to control the upper part of the formation of the petroleum system.Its source is native reservoir of Nantun section.Its reservoir is Daer section.And its cap is Yimin section.Through researching we found that inversion structural oil and gas reservoir formation is closely related to the degree of inversion.This difference is due to the late east-west compressional stress field acting on the different strike pre-existing trunk formed by normal faults.Weak intensity inversion traps such as NNE strike concealed fault spreading type inversion traps are the preferred target looking for this kind of secondary oil and gas reservoirs.
