摘要
曲面曲率的几何意义可以反映曲面一点邻近区域的具体形态和变形特征,因而可以用主曲率法来评价和预测油气储层裂缝分布和发育程度,应用这种方法对泌阳深凹陷中心安棚鼻状构造带进行了评价。研究结果表明,采用主曲率法预测的结果与地质解释、钻井和测井资料吻合较好,具有很好的应用前景。
The geometrical meaning of the curvatures of curved surface reflects the shape and deformation characteristic of the adjacent area of one point.It can be applied to appraise and predicate distribution of reservoir fractures.Deformation zone was studied by the method in Anpeng area of Biyang Depression.The results show that the method is consistent well with the geologic information and logging data.This paper will prove that the method has a very good application prospect in reservoir fractures.
