摘要
将在地质方面常用的二元二次趋势面问题 ,推广到 P元 Q次超趋势面 ,并分析了其中的原理和计算方法 .通过对双河油田江河区 4油组 5~ 9油层顶面深度预测结果表明 ,该方法在预测油藏空间展布方面优点较为突出 .与空间样条曲面插值方法外推预测的顶深趋势变化比较 ,用 P元 Q次超趋势面和其他方法联合预测的油层顶深结果与实际的构造起伏很接近 。
A P-variate Q-time hyper-trend surface method is derived on the basis of binary quadric hyper-trend surface method, and its algorithm and programming method are presented. The P-variate Q-time hyper-trend surface method has remarkable advantages in the respect of predicting the distribution of oil reservoir. 5-9 oil layers in unit 4 in Jianghe block, Shuanghe oilfield being taken an example, the variation trend of their top surface depth is predicted separately by the P-variate Q-time hyper-trend surface method and binary quadric hyper-trend surface method, and the results show that, by combining the P-variate Q-time hyper-trend surface method with other geological modeling methods, such as spline curved interpolation, the obtained result will be more accurate.
