| 摘 要： | 油气化探的异常确定一直是争论较多的问题之一，尤其是在存有背景差异的情况下就更为突出。分别划分异常下限带有较强的人为因素，而趋势分析面对情况比较复杂的地学空间场，也会因为拟合度或边界效应等原因而出现较大的误差。作者在本文中采用了傅立叶带通滤波，消除了空间场中的北景差异，在塔北油气勘探的应用中取得了较好的效果。

| Abstract: | In geochemical exploration for oil and gas, the determination of the lower limit of anomalies is one of the most disputed problems, especially in the situation of different backgrounds. The relevant way to adopt different regional lower limits is mixed up artificial factors, and Trend Analysis may produce pretty serious errors due to boundary effects and fitting degree for complex geo-spatial field. In this paper, the band filtering of Fourier transform is employed to eliminate the background difference of geochemical field of oil and gas. This method is applied to clarify anomalies with satisfying results in North Tarim Basin. |
