南堡凹陷高柳地区东营组沉积体系及岩性油气藏成藏模式

Sedimentary system and lithologic reservoirs accumulation modes of Dongying formation in Gaoliu area,Nanpu sag

  • 摘要: 南堡凹陷高柳地区东营期受陆源碎屑供给变化的影响,储层多期叠加,横向变化快,预测难度大。通过对高柳地区东营组物源、沉积体系研究,明确了沉积时期物源方向及沉积体系时空展布特征;在沉积体系研究基础上,构建了不同沉积体系的岩性油气藏成藏模式。研究认为:东营组物源主要来自柏各庄凸起和马头营凸起方向,东营期主要发育了扇三角洲、半深湖-深湖等沉积体系,东营组可分为陡坡带成藏体系和缓坡带成藏体系,油藏类型主要包括上倾尖灭油气藏、超覆不整合及扇根侧向封堵型油气藏,东营组斜坡带油气成藏明显受到沉积特征控制,岩性油气藏是下步勘探的重要领域。

     

    Abstract: Affected by terrigenous clastic supply change of Dongying formation in Gaoliu area,Nanpu sag,reservoirs are characterized by multiphase superposition and quick lateral changes,and there is a great difficulties in reservoir prediction.Through systematic study on sedimentary provenances and sedimentary system of Dongying formation in Gaoliu area,the sedimentary provenance directions and space-time distribution characteristics of Dongying formation have been made clear.On the basis of sedimentary system study,lithologic reservoir accumulation modes at different sedimentary systems have been established.The study results indicate the sedimentary provenances of Dongying formation mainly come from uplifts of Baigezhuang and Mayingtou.Dongying formation of Gaoliu area mainly developed fan delta,half deep lacustrine-deep lacustine sedimentary systems,the reservoir systems can be divided into steep slope zone and gentle slope zone,and the reservoir types mainly include the updip pinchout reservoirs,lens,overlapping unconformity and fan root lateral sealing reservoirs.The slope hydrocarbon reservoirs of Dongying formation in Gaoliu area are obviously controlled by sedimentary characteristics and the lithologic reservoir is an important area for exploration in the next step.
