摘　　要：在油气盆地分析工作中,需要处理大量的地质数据和地质图件,其中一部份位于等值线之上的地质变量值自然可以直接读取,但是油田勘探工作往往需要获得等值线之外区域范围的数值,这时依靠传统的人眼判识,不仅存在较大的随机误差,而且巨大繁杂的工作量极大地影响了勘探工作的高效性,因此这里将介绍探索利用Mapgis与Surfer软件结合提取等值线图所需范围内(包括处于等值线上的及等值线之外区域)的数据。In the analysis of oil and gas basins, we need to handle large amount of geological data and geological maps in part of which the geological variables located above the contour lines can be read directly. But during oil exploration we often need to get the value that outside of the contour, then lying on traditional identification with human eye, not only the large random error but also the enormous complexity of workload greatly affects the efficiency of exploration work. This paper will introduce and explore the use of combing Mapgis and Surfer software to extract the necessary data, including from the part in the contour line and outside the contour lines.
