断层识别与定量解释方法进展

在油气勘探中，断层识别在地震资料解释扮演重要的角色，断层解释的准确性和合理性直接影响构造成图的精度和开发方案的设计。准确预测断层发育带是评价裂缝型储层的前提，更是提高裂缝型油气藏勘探效率和开发水平的关键。本文综合近几年SEG年会相关文献，介绍了国内外断层解释方法的新进展，重点阐述了国内外最新的断层识别与定量解释方法：如连续相位谱体积曲率属性、3D Radon变换滤波、倾斜引导面模型、方向约束蚁群算法、改进的AFE TM 技术等新方法在断层识别与自动化识别上的应用改善，以及断层垂直断距与消断层作用成像提取层位技术等在断层定量与精细解释上方面的新方法及应用。

New Advances in Theory and Application of Fault Identification and Quantify Interpretation

In oil--gas exploration, fault identification plays an important role in seismic data interpretation. The accuracy and validity of fault identification affect the precision of build- ing of structure mapping and the designation of development programs directly. A precise prediction of fault zone is the premise of fractured reservoir evaluation, and also is the key of the improvement of exploration efficiency and development level in fractured reservoir. The paper summarizes the newly SEG Annual related papers, and introduces the new fault interpretation methods and developments at home and abroad, then makes a detailed discus- sion about fault identification and quantitative interpretation methods, such as volumetric curvature from continuous phase spectrum, a windowed 3D Radon transform filtering, dip guided facet model edge detector, automatic fault tracking approach based on ant colony al- gorithm, advanced AFE process, etc. Then it points out their improvement in fault identi- fication and automatic identification applications, also discusses the new methods and appli- cations of fault displacement and geologic horizons extracting by unfaulting and unfolding techniques.
