Based on the concept of three-dimension development and by analyzing the structural evolution and play characteristics in Lufeng sag and deepening researches to tap the Neogene potential in Lufeng 13-1 oilfield, a new idea was proposed that Hui-Lu lower uplift once "drifted" from Paleogene to Neogene. By integrating qualitative to quantitative techniques of reservoir description, the sedimentary characteristics and reservoir-seal assemblages were revealed in Paleogene Enping Formation, and a model of hydrocarbon accumulation was concluded for Paleogene in Lufeng sag from analyzing the drilling data in Lufeng area. All these works have resulted in successful drilling of Appraisal Well LF13-1-9PH, by which the first commercial oil accumulation of Paleogene Enping Formation is diseovered in Pearl River Mouth basin. Thus, this breakthrough at Enping Formation in Lufeng 13-1 oilfield is promoted by the knowledge jump of structure high "drifting", which could be quite important to Paleogene exploration and development in Pearl River Mouth basin.%基于立体开发理念,在剖析陆丰凹陷构造演化和成藏组合特征、深化陆丰13-1油田新近系挖潜研究的基础上,提出了从古近系到新近系惠陆低凸起构造高点"漂移"的新认识;采用从定性到定量的储层描述技术组合,揭示了古近系恩平组地层沉积特征和储盖组合配置关系;通过陆丰地区钻井资料分析,总结了陆丰凹陷古近系油气成藏模式.在上述研究的基础上,成功地推动了古近系评价并LF13-1-9PH井的钻探,发现了珠江口盆地第一个具商业价值的古近系恩平组油藏.构造高点"漂移"规律认识上的突破,推动了陆丰13-1油田古近系恩平组的突破,对南海珠江口盆地古近系勘探开发具有重要意义.
