研究了井中三分量磁测数据转换和绘图的方法,针对轴向系统磁力仪,推导了斜井的三分量磁测原始数据转换公式;基于面向对象的程序设计思想,采用VB 2005开发了一套井中三分量磁测数据转换及绘图软件;利用实际资料对软件进行了综合测试,结果表明,该软件能够快速有效地进行井中三分量磁测数据转换,并根据解释上的需要精确地绘制ΔZ曲线图、ΔH矢量图等磁异常图,完成了井中三分量磁测数据的计算机自动转换及绘图的功能,具有一定的应用前景。

THE DESIGN AND IMPLEMENTATION OF THE DATA PROCESSING AND DRAWING SYSTEM FOR BOREHOLE THREE-COMPONENT MAGNETIC MEASUREMENT

In this paper,the methods of data processing and drawing for borehole three-component magnetic measurement are discussed.The data processing formulae of tilted well for the axial system magnetometer were inferred.Based on Object-Oriented Programming(OOP) and using VB2005 as the program language,the authors successfully designed and implemented a data processing and drawing system for borehole three-component magnetic measurement.In order to test the system,this paper has described an example of borehole three-component magnetic measurement,which proves that the system can effectively process the data and accurately draw such graphs as graph and vectorgraph.As a data processing and drawing system for borehole three-component magnetic measurement,this system is perfect and has a wide application vista.
