断块油藏精细构造研究

精细构造研究是断块油藏精细描述的重要组成部分，它主要利用多种手段和方法重新认识和建立油藏的三维例构造形态和特征。提出利用层次性进行精细构造表征，遵循从大到小原则，逐级细致研究，逐级重新落实，得出正确的结论。主要应用井资料，分地层划分对比、开发动态分析和微构造研究3个方面论述了认识和落实小断层的方法。结合段六拨油田的实际资料，通过以上几方面研究，取消了区内原先解释的3条断层，对油田内部断层重新组合，建立了油藏三维构造模型，并指出了段六拨油田剩余油的挖潜方向和潜力区。

Fine Structure Research of Fault Block Oilfield

The purpose of fine structure research is to reknow work area's structural characters and rebuild 3D structural model by using seismic data and geologic data.This article introduces hiberarchy into fine structure research.And discuss three ways to confirm the existent possibilities of faults.Combining the facts of Duan Liubo oilfield,we cancel three faults,confirm Guan 73 fault,and point out the potential areas for remaining oil exploration by rebuilding work area's structural characters model.
