摘要
考虑到裂缝发育的方向性,文中提出基于玫瑰图分析的方位曲率检测裂缝方法。方位曲率属性技术能够加强某一分析方向上的裂缝特征在曲率属性上的显示,为检测和展示不同方向上裂缝发育特征提供了手段。玫瑰图分析能够显示出裂缝发育的方位角,为方位曲率分析方法中的方位角选择提供解决方案。数值模拟结果表明,此方法正确可行。实例分析结果表明,在玫瑰图分析基础上的方位曲率属性技术,排除了非期望方向的裂缝信息干扰,得到了精细显示的裂缝发育特征曲率属性图。解释人员能够获得期望方位角上的裂缝展布特征,为后期的钻井部署提供有力依据。
Considering the directivity of fracture development, the azimuth curvature method to detect fracture based on the analysis of rose diagram is proposed. The azimuth curvature attribute technology can strengthen to show the special direction of fracture characteristics on the curvature attributes, which offers the way to detect and display the fracture development characteristics of different direction. Rose diagram analysis can show the azimuth angle of fracture development and can provide the azimuth angle selection for the azimuth curvature attribute technology. Numerical simulation results show that this method is feasible. Example analysis results show that the orientation of rose diagram analysis based on the azimuth curvature attribute technology can rule out the interference information of unexpected direction of fracture, and get the curvature attribute diagram with detailed instructions of fracture development characteristics. Interpreter can get expected azimuth distribution characteristics of fracture, providing the powerful basis for later drilling deployment.
