本文根据灰色预测理论,应用四阶GM模型[1] 来模拟反映构造和基底变化的重力区域场,从而获得重力剩余场。分析表明,用该灰色方法计算所得的新疆塔里木盆地北部托库测区剩余重力场可解释为油气微重力异常。

Based on gray forecasting theory, the 4 order gray model proposed by the author is applied to model the gravity regional field reflecting the tectonic and basement change. Thus the residual gravity field is then obtained.The application evidence shows that the residual gravity anomaly can be explained as an anomaly of oil and gas in Tuoku survey region, Tarim Basin.
