本文主要研究的是基于测井数据的地质图矢量化方法。首先要对测井曲线及地质图进行预处理，对于含有不同种类噪声的图像，通常采取不同的方法进行处理，甚至需要使用几种方法的结合来处理，才能达到预期的效果。地质图中含有原始测井曲线、等值线和等高线以及各种地质符号等相关元素，通过图像分割算法和提取算法分离出测井曲线，然后运用曲线追踪方法来追踪原始的测井曲线，输出矢量化的DXF格式图像。 曲线追踪过程中会遇到不同类型的测井曲线。对于含有坐标的测井曲线，追踪结果往往会随着坐标格追踪下去，导致追踪的结果偏差。因此通过相关算法的改进，在处理含有坐标格的测井曲线时能够达到良好的效果。在测井曲线的提取方法中，分别介绍了实线和虚线的提取方法。对于实线型的测井曲线采用的是基于中轴变换的实线提取方法，而对于虚线型的测井曲线采用的是基于重心拟合的虚线提取方法。从测井曲线图中衍生出的等值线图和等高线图也是非常具有代表性的地质图件，所以对于这类图像也进行了相关的研究。 矢量化的地质图存储格式，即DXF格式的存储对于本文的研究工作至关重要。在熟悉和了解DXF格式的过程中，对其存储方法进行了相关的研究，并且在实际开发过程中得到了应用，达到了预期的效果。

The article focuses on the vector method of the geological map base on the logging data. First, we need to preprocess the well logs and geological maps. For images which contain different types of noises, we usually take different methods to deal with them, even for other images, it needs to use combination of several methods to deal with them in order to achieve the desired results. Geological maps contain original log curves, isopleths, contours and a variety of geological symbols, as well as other related elements. It could isolate log curves through the image segmentation and extraction algorithms, and then we use curve tracking methods to track original log curves, and output the DXF format image. In the curve tracing process, it will meet different types of logging curves. For the well log based on grid, it often tracks down with the coordinate grid, which can lead to incorrect tracking results. Thus, by the improved algorithm, it can achieve good results when handling with the logging curves containing the coordinates. In the logging curve extraction methods, it introduces solid and dashed lines of tracking method. For the solid curve of log, it is based on the real axis line extraction methods, whereas for the dashed curve log, it uses the dotted line method based on the extraction fitting center of gravity. Isopleths and contour derived from logging curve are also very important geological maps, so this paper also carries out some studies in this area. Vector-based geological map storage format, the DXF format storage, is essential for this research work. In the process of understanding DXF format, it takes some research on the method of storage, and it has applied to the actual developments and achieved desired results.
