| 摘 要： | 番禺低隆起—白云凹陷北坡地区是珠江口盆地最有利的油气勘探区域之一,如何在现有勘探成果的基础上进一步拓展勘探领域,对珠江口盆地东部天然气勘探的持续发展有着重要的意义.以层序地层学原理为指导,结合地震、测井、钻井、古生物等资料,分析表明该区的沉积特征主要受控于特殊的古地理位置——陆架坡折带,通过多种研究方法,确定出21 Ma陆架坡折带的分布范围,总结了其与油气藏的关系.21 Ma陆架坡折线呈弧形向海盆方向分布,大致与番禺低隆起和白云凹陷的分界线平行,西侧为近东西向,向东则逐渐向北东方向延伸.陆架坡折带对隐蔽油气藏的成藏具有重要控制作用,该区主要存在3种与陆架坡折带发育有关的油气藏类型,即构造油气藏、岩性油气藏、构造-岩性油气藏.

| Abstract: | Panyu low uplift-north slope of Baiyun depression is one of the most favorable oil and gas accumulation zone of Pear River Mouth Basin.Five gas fields have been found by far in this area which are PY30-1,PY34-1,PY35-2,PY35-1 and LH19-5 gas field and multiple gas-bearing structures.The OGIP is about 120 billion cubic meters.How to extend new oil and gas exploration areas on the basis of exploration results is significant for the sustainable development of the natural gas exploration in Pearl River Mouth Basi... |
