摘　　要：通过扫描获得的测井曲线由于图纸磨损等原因,二值化后会出现断裂,破坏了曲线的连续性和完整性,引起曲线的骨架变形,增加了曲线矢量化的难度.利用数学形态学的理论,根据曲线断裂特点,对矢量化前的测井曲线进行修复,取得了良好的效果.When a well logging curve obtained by scanning a sheet of worn drawing is processed by binary value (i.e., '0' and '1'), some breakingpoints may arise. This causes the distortion of the curve skeleton and increases the difficulty in the vectorization of the curve. In order to ensure the continuity and the integrity of the curve, a method of restoring the well logging curve by means of the theory of mathematical morphology is put forward. The result of the method is very satisfied.
