地层介质非均质性预测方法技术研究

STUDY ON PREDICTION TECHNIQUE BY STRATIGAPHIC MEDIUM ANISOTROPY METHOD

本文详细地论述了预测地层介质非匀质性的变差函数法和计算技术。通过某地区砂Ａ 层非均质性预测研究表明，揭示了砂Ａ层展布连通程度的变化规律，为砂Ａ 层的开发提供了可靠依据，它是一种有效的预测方法和有力的工具，具有广阔应用前景。

The prediction technique by stratigraphic m edium anisotropy is a key problem for oil&gas exploitation. The paperpresents a m ethod ofvariance function and com pution ofsem ivariancefunction. Using this m ethod, w e can extract m ultiple param eters w hich indicate anisotropy of stratigraphic m edium from seism ic data. The param eters consistofvariable distance (a), value ofbase plateform (C0+ C) and com prehensive param eter (I0). The application of this prediction technique to Sand (A) in Hexinchang, Sichuan hasachieved satisfactory result and therefore is an effective prediction m ethod.
