灰色系统预测法对时间序列的预测有较高的精度。地层的沉积过程是一个时间序列, 地震记录道则反映了地层的数字特征。本文提出用灰色系统预测模型提取地震剖面异常信息的方法, 作为直接找油气的一种尝试。实例显示, 该方法能有效地提取地震剖面的异常信息, 实际资料的处理结果与实际并位的含油气显示吻合。

The grey system has a high precision for the time series prediction. The sedimentaryprocess of strata is a time series, and seismic traces reflect the numerical characters of strata. Thispaper introduces the extraction method of anomaly information in seismic sections by the greysystem prediction model in an attempt to detect hydrocarbon directly. The effectiveness of themethod is demonstrated by an actual example. The result obtained is coincident with the actualshowing of oil and gas.
