摘　　要：针对测井曲线的矢量化问题,在讨论频域和空域的测井曲线图像预处理优缺点的基础上,采用了矢量跟踪的 方法来处理测井曲线.对不同油田的20多种测井图纸样本进行了测试,实验表明矢量化的精度可达98％.An improved method is proposed to vectorize of petroleum log curves. On the basis of the advantage/disadvantage analysis of the image preprocessing in frequency domain and in spatial domain, a method of vector tracing is developed for the processing of petroleum log curves. Experiments have been done on more than 20 sheets of petroleum log blueprints from different oil companies. The results show that the accuracy of vectorization can reach 98%.
