广义翁氏模型与水驱曲线的联解法

COMBINED SOLUTION OF GENERALIZED WENG MODEL AND WATER DRIVE CURVE.

在油藏工程中，广义翁氏模型和水驱曲线是两种重要的预测方法。前者主要用于预测不同驱动类型油气田的产量、累积产量和给定经济极限产量条件下的可采储量；后者主要用于预测水驱油田，在给定经济极限含水率条件下的可采储量。然而，这两类方法都有自身的局限。作者将广义翁氏模型与甲型、乙型水驱曲线相结合，提出了一种新的预测方法。该方法既可以预测水驱油田的产量、累积产量、含水率和体积波及系数。

The generalized Weng model and the water drive curve are two important prediction methods in reservoir engineering. The former is mainly used to predict oil production, cumulative oil production and recoverable reserves under given economic limit oil production for oil and gas fields of different drive types. While the latter is used to predict recoverable reserves of water drive oilfield under given economic limit water cut. However, both of them have their own limitations. Based on combined solution of the generalized Weng model and the water curves of A and B types, a new method is provided. For water drive oilfield, the method can be used to not only predict oil production, cumulative oil production, water cut and volumetric sweep efficiency, but also predict recoverable reserves and mobile oil in place.
