交互式智能型地层倾角测井精细构造解释技术

AN INTERACTIVE INTELLIGENT TECHNOLOGY OF FINE STRUCTURAL INTERPRETATION OF DIPLOG

交互式智能型精细构造解释系统利用工作越丰富的图形及交互功能，采用交互式模式识别及矢量滤波准确确定组合矢量模式，提取构造信息，计算构造解释参数；根据专家经验、地区知识和倾角模式理论所建立的知识库进行的交互式精细构造解释和分析解决了倾角测井构造解释的多解性问题，保证倾角解释的正确性；最终可绘制出井周各方位的构造剖面图和构造等值线图．在塔里木盆地的应用表明，该方法所得到的结果具有良好的一致性和可靠性，并充分显示了它独有的精细构造描述特点．

Diplog has been used to find geologic structures widely now. Having high resolution,diplog has advantage to determine small folds and small faults, which are difficult to be found by other technology. In our system developed in Sun workstation, the interactive vector pattern recognization and vector filter are used to determine dip vector combination pattern, extract structural data, calculate structural elements. A technology of fine structural interpretation and analysis, which uses knowledge base built on expert experience, geological knowledge and dip arrow pattern theory, is provided to resolve the question in which one combination vector pattern can correspond to more than one structural types. The interactive interpretation quarantees right result. Finally, cross section and contour map from dipmeter data can be provided. The application of the system in Tarimu demonstrated that the results have good consistency, good reliability,and the distinctive property of fine structural description.
