油田测井曲线矢量化软件的设计与实现

Developing software for vectorizing oilfield well logging curves

在早期石油勘探过程中,许多测井资料是以纸质图件形式保存的,继续保存面临许多困难,也不利于使用,对这些图纸资料进行数字矢量化必要且具有实用价值。详细分析这些资料特点并进行归类后,研究不同预处理方法的特点,实现了对纸质资料的有用信号地恢复与提取。根据测井曲线特点,设计并实现了自动追踪曲线的算法,通过实例验证该处理技术可以对这些资料进行矢量化,具有高性能、可靠性等特点,方便相关资料存储与使用。

In early oil exploration,many well logging data were kept in paper version,which makes it difficult to preserve on or utilize.So,it's urgent and practical value to keep such data in electronic edition.The analysis of the classification of the old well logging data and the study of different pre-processing methods results in the realization of the restoration and extraction of the useful signature of the paper version.The auto-tracking algorithm is built up based on the characteristic of the well logging curve.The program can be used to make the paper version data vectorized by applying to process the data,which is effective,reliable and convenient to preserve and utilize such data.
