摘要
莺歌海盆地中央泥拱构造带位于莺歌海凹陷中心区 ,天然气资源极其丰富 ,具有多套区域性储盖组合 ,存在着一批大型泥拱背斜圈闭。其特有的地质特征使泥底辟构造带广泛形成具有特色的油气藏。东方气田位于该构造带上 ,其泥拱活动强度较弱 ,刺穿不明显 ,但东方 1- 1成为大型气田有其独特的条件和成藏机制 :相当厚的沉积物 ,纵向上多套生储盖组合配置 ,高地温梯度的促进作用。所有这些为东方 1-
Central mud manipulation structure belt of Yinggehai Basin lies in centers of Yinggehai depression, enriches gas resource, includes several sets of regional combination of reservoir and seal, along with a bath of large scaled mud manipulation anticline traps. Being its extra geological qualities, special oil gas reservoir come into being extensively over the mud diapiric structure belt. The DF gas well lies on the belt, where the mud manipulation is comparvetly weak and it's diapers isn't obvious. But there are extra conditions and reservoir formation system which make well DF1-1 become large scared gas reservoir: extreme thickness depositions, the vertical existation of several sets of combination of generation reservoir and seal, the activation of high thermal necessary. All become the necessary condition of the DF1-1 gas field.
