摘要：

北部湾盆地涠西南凹陷经历了下断上拗的发展演化历程。古近系复杂断块油气成藏研究一直是油气勘探的重点。位于②号断裂东段的涠洲D-8含油构造经历了研究—钻探—再研究—再钻探的循序渐进、层层推进的勘探历程。该构造已钻3口井反映该区带成藏模式主要为岩性油藏，储层为来自东北长轴方向不同期次的砂体，但仅具有大的沟源断层的砂体才能成藏。经精细刻画该构造区发育多个具备沟源断层的砂体，还具有较大勘探潜力。 

Abstract:

Weixi’nan sag in Beibuwan basin had undergone an evolvement of fault-depression. The Paleogene fault blocks have always been the focus for oil-gas reservoir research. Weizhou D-8 oil-bearing structure, situated in the eastern No.2 fault zone, had been studied, drilled, restudied, redrilled. According to the three boreholes, the oil reservoir is chiefly controlled by lithology with sandstone bodies at variable times from northeast as reservoir, but only those with big channel faults can form oil reservoirs. This paper studies in detail several sandstone bodies with channel faults in this structure, which are supposed to be oil potential.

Key words: complicated fault block, drilling, lithologic oil reservoir;Weixi’nan sag
