| 摘 要： | 数据处理和成图技术在地球化学和找矿研究中是十分重要的。根据地球化学数据的总体和局域分布型式总结发展了数据预处理技术,二维空间地球化学数据处理应该包括数据预处理,结合分析并估值,数值滤波３个环节。上述研究思路在塔里木盆地油气化探研究中取得了明显效果。

| Abstract: | Data processing and mapping techniques have proved very important to metal and oil/gas geochemical exploration. In this paper, a local data processing technique is presented in the light of global and local distribution patterns of geochemical indexes under consideration. A number of methods, including simple and universal Kriging, conditional simulation, two_dimensional Fourier filtering, wavelet filtering and non_trained pattern recognition, are then presented and integrated into a comprehensive software. The software developed in C++ of the Windows 95 environment has been applied to the geochemical data processing for the purpose of geochemical exploration of both oil/gas and metals. In addition, this software has been successfully employed to delineate the prospecting targets in Tarim basin and those of metals in Anhui Province. |
