| 摘 要： | 主曲率法和高斯曲率法是评价和预测油气储层裂缝分布和发育程度的两种数学方法，应用这两种方法对泌阳深凹陷中心安棚鼻状构造带中的白云岩储层的构造成因裂缝进行了评价。研究结果表明，在凹陷内部构造变形幅度相对平缓的地区，采用主曲率法预测构造裂缝时存在较大偏差，而高斯曲率法(GC)的应用结果与地质解释、钻井和测井资料吻合较好。应用结果表明，高斯曲率法是一种预测和评价构造裂缝分布规律的有效方法，具有很好的应用前景。

| Abstract: | The principal curvature method and Gauss curvature method are two mathematic methods for appraising and predicating distribution of reservoir fractures.Dolomite reservoir fracture system, which was structural fracture,was studied by these two methods in Anpeng area of Biyang Depression.The results show that the principal curvature method has obvious deviation when used for a gentle structure latitude district. On the contrary, the predicating result by Gauss curvature method is consistent well with the geologic information and logging data. This paper will prove that Gauss curvature method has a very good application prospect in reservoir fractures. |
