【摘要】 为明确青东凹陷北部地区的油气成藏规律、勘探潜力及下步重点勘探方向,应用石油地质综合研究技术,利用区内录井、测井、地震和分析化验等大量基础资料,对该区的油藏特征、分布规律及控藏因素进行系统研究。研究表明:青东北部地区油藏类型多样,以构造类油藏为主。研究区具有近源成藏优势,油源供应充足,烃源岩控制油气纵向分布,断层附近的构造圈闭控制油气富集,储层物性条件控制油藏产能。更多还原

【Abstract】 To recognize the petroleum reservoir accumulation law,exploration potential and the direction for further exploration in the north area of Qingdong sag,the reservoir types,the distribution characteristics and the accumulation controlling factors were studied systematically,applying petroleum geological research techniques,based on the massive first-hand data,such as well-logging data,seismic data and laboratory data,etc. The research shows that structural reservoir and litho-structural reservoir are the main hydrocarbon reservoir types in the area. With the generation and expulsion center located at the north sub-sag,the research area has the advantages of near-source and sufficient supplication. The vertical distribution of petroleum reservoir is controlled by source rocks. The structural traps near faults control oil and gas enrichment. The reservoir physical properties control the oil production.更多还原
