哥伦比亚油气资源丰富,为南美第4大油气生产国,是南美地区值得重点关注的国家之一。该文以石油地质理论为指导,对哥伦比亚的油气地质特征和油气分布规律进行了分析,指出了其勘探潜力。研究认为哥伦比亚具有构造复杂多变、盆地类型多、沉积地层发育齐全、烃源岩优越、储盖组合配置良好和圈闭类型丰富的特点,其油气分布集中,重油、常规油平面上分异明显,油气成藏受烃源岩、运移通道和储盖组合的控制;东部构造区、前陆盆地、第三系、构造圈闭、常规油气为未来勘探重点。研究结果能为哥伦比亚的油气勘探开发提供参考。

With rich oil and gas resources,Colombia is the 4th major petroleum producer in South America and attracts much attention.Guided by petroleum geology theory,the characteristics of petroleum geology and the principles of petroleum distribution have been studied,and the exploration potential has been summarized.Colombia is characterized by complex structure,various types of basin,complete sedimentary strata,excellent source rock,good reservoir-cap combination and various types of trap.Oil and gas are concentrated in several basins.Heavy oil and conventional oil are distinctive on plane view.Petroleum accumulation is controlled by source rock,migration pathway and reservoir-cap combination.The eastern tectonic zone,foreland basins,the Tertiary,structural traps and conventional oil and gas are the exploration focuses in the future.The studies provide a reference for the exploration and development of oil and gas in Colombia.
