摘　　要：DF14井在莺歌海盆地中深层黄流组一段(压力系数大于1.9)获得优质高产天然气流,具有重要的领域突破意义。分析了黄流组高压气藏成藏机制,指出气藏具有纵向聚集、高压封盖、大型海底扇砂岩储集、向底辟构造远端超覆尖灭形成侧封的岩性气藏新模式。A gas pay with good quality and high production was discovered in Member 1 （with a pressure coefficient 〉1.9）, Huangliu Formation of the middle-deep interval in Yinggehai basin by drilling Well DF14, having the significance to make a play breakthrough. The accumulation mechanism was analyzed for this overpressure gas reservoir, and a new model of lithologieal gas reservoir was presented, which is characterized by vertical accumulation, high-pressure sealing, reservoiring in large submarine fans and lateral sealing by a distal overlap toward the diapir structure.
