模式识别在预探井钻前储层预测中的应用

APPLICATION OF PATTERN RECOGNITION IN RESERVOIR PREDICTION IN PRE-EXPLORATORY WELLS BEFORE DRILLING

在开钻之前，预探构造上除了地震测网和地震剖面外，几乎再没有其它能够揭示地下储层性质的探测资料。鉴于钻前储层预测的巨大意义，本文将模式识别引入到这个领域，力图通过“由已知到未知”这一途径来预测预探井内的岩性分布。实际资料证实，这种方法具有明显的使用价值。

There is almost nothingbut data of seismic network and seismic profiles to reveal thefeature of subsurface reservoirs on a pre-exploratory structures before drilling. Sincereservoir prediction before drilling is very important, a new method' patternrecognition' is introduced in this paper so as to predict the lithological distribution in preexploratory wells. It has been proved by practice that this method is evidently valuable inapplication.
