| 摘 要： | 利用空间地球化学数据波谱分析技术,可以获得更为丰富的地球化学信息,以便从多个层面认识研究区的地球化学特征,从而能把握各种信息中所包含的与油气相关的实质性内容,较为准确地提取油气异常信息,客观地预测油气远景区.研究表明,波谱分析的低频分析结果通常给出地球化学场的主特征轮廓,中频滤波结果与油气田有较好的吻合性.高频滤波结果反映的是难以认识的浅表效应和噪声信息.很好地利用低频和中频滤波结果,结合不同频率域的滤波结果,能较为准确地提取油气异常信息.

| Abstract: | With wave spectrum analytical techniques of spatial geochemical data, one can obtain abundant information of the geochemical field, understand characteristics of geochemical fields of study areas from various aspects, extract essential oil and gas related knowledge from all kinds of data, pick up more accurate anomalous oil and gas information and objectively predict oil and gas perspective areas. Case histories show that low frequency filtering reveals the main features of geochemical field, intermediate frequency filtering is consistent with oil and gas fields, and high frequency filtering reflects shallow effects and noises which are difficult to be interpreted. By combining low and intermediate frequency results with results from different frequency fields, one can pick up anomalous oil and gas information more precisely. |
