摘　　要：在分析传统的地质对比推测钻井取芯层位的基础上,提出用灰色理论GM(1.1)模型,预测钻井油气层深度及厚度的方法,该文简述了针对油气层深度预测的数据预处理方法,给出了预测计算实例。为使预测有可靠的准确性,提出了对预测进行关联度系统分析方法,也给出了分析实例。该方法具有所需数据少,预测速度快,准确度高的特点,预测深度的绝对误差小于2m.可用于现场地质钻井取心卡准层位及异常高压油气层位置的精确预报。On the basis of analysing traditional geology correlation to hypothesis drilling coring layer, the text presents using Gray Method (GM1.l )model, to predict drilling oil and gas depth and thickness, and the data pre-processing way, the author gives counting example. In order to make predetection have reliable precision, the text also gives the method of association analysis to the predetection and some examples. The method has the advantage of less data involved,rapid,high accura cy, the absolut error is less than 2m. This method can be applied in wellsite geological coring layer and abnormal high oil gas pressure precise predicting.
