摘要:
墨西哥湾深水作为全球深水勘探的热点盆地之一,日益成为各大石油公司竞逐的勘探领域。通过对其石油地质条件以及圈闭类型和成藏模式的探讨,指出其圈闭勘探呈明显的分带性,且平面分布特征明显;主要圈闭类型通常可分为4-way和3-way两大类,但以3-way类型的居多;墨西哥湾深水勘探目标的关键成藏要素为圈闭、储层和油气运移,但对于不同的勘探区带,其侧重点各有不同;通过对3个勘探区带的关键成藏要素的比较,指出从成藏条件来看,东部侏罗系风成砂勘探区带优于古近系Wilcox勘探区带,中新统勘探区带稍逊于古近系Wilcox勘探区带。

Abstract:
As one of the most sought-for basins in global deep water oil exploration, the deepwater Gulf of Mexico (GoM) has become a focus operation area for major oil companies. According to the analysis of petroleum geologic conditions and the discussion on trap types and oil accumulation models, it is revealed that the distribution of exploration plays is characterized by obvious zonation. There are two types of traps, named 4-way and 3-way, with 3-way as the majority. Key factors for exploration prospects in the deep water GoM are trap, reservoir and migration, while focus varies in different plays. Through comparing oil accumulation elements of the three plays, it is concluded that the Jurassic Norphlet sand play shows superiority to the Wilcox play, and the Miocene play shows inferiority to the Wilcox.
