摘要：

童氏曲线图版法是注水开发油田标定可采储量的主要方法。随着中国注水开发油藏相继进入高含水期,出现许多实际油藏的含水率与采出程度关系与童氏曲线图版吻合性较差的现象。为此,在新的渗流特征方程的基础上,利用Welge方程,导出了童氏曲线的通式,完善了童氏曲线的理论基础。童氏曲线的通式在一定条件下,可以转化为经典的童氏曲线及其改进式,其对应的水驱特征曲线也可在一定条件下转化为马克西莫夫水驱特征曲线、校正马克西莫夫水驱特征曲线和沙卓罗夫水驱特征曲线,表明童氏曲线的通式具有较好的适应性。通过丘陵油田三间房组油藏的应用,给出了绘制实际油藏童氏曲线图版的方法和确定油藏特征参数的方法。

Abstract:

Tong’s curve chart is the primary method for calibrating recoverable reserves in water-flooded oilfields. As water-flooded reservoirs in China produce more and more water one after another, the relationship between recovery percent and water cut in many reservoirs is becoming inconsistent with Tong’s curve. In this paper, on the basis of new seepage characteristic equation, we derive the general formula of Tong’s curve by using Welge equation, and improves the theoretical basis of Tong’s curve. Under certain conditions, the general formula of Tong’s curve can be converted into the typical Tong’s curve and its improved formula, and its corresponding water drive characteristic curve can be converted into Maksimov water drive characteristic curve. Since it can correct Maksimov water drive characteristic curve and Shadrov water drive characteristic curve, the general formula of Tong’s curve is more adaptable under certain conditions. Taking the reservoir of the Sanjianfang formation in Qiuling oilfield as a case, the methods for building actual Tong’s curve and determining reservoir characteristic parameters are proposed.

Key words: Tong’s curve chart, water-flooded reservoir, seepage characteristic, water drive characteristic curve, derivation, application
