摘　　要：在老油田开发中后期,现有压力预测与检测方法已不能适应钻调整井时的压力计算,其主要原因是传统的压力预测方法是在原始地层沉积环境情况下建立的。提出利用油藏工程方法与油藏数值模拟方法,可给出拟钻调整井的剩余油富集区的压力分布与精度相当高的压力预测值。It is not feasible for current methods to predict the formation pressure during drilling in adjustment wells at the mid-later development stage of oilfields because it is based on original sediment environments of reservoirs. In this paper, a novel pressure predication method is presented that the pressure distribution in abundance residual oil area and the high precision pressure value can be obtained for drilling adjustment wells using the reservoir engineering method and reservoir numerical simulation method.
