摘要： 童氏图版法在国内外注水开发油田采收率预测中得到了广泛应用,但它只能应用于油田开发的中后期,对于采出程度较低的水驱高粘度油藏和低渗透复杂断块油田,童氏图版对含水率与采出程度的描述与实际不符。从数学意义及油藏开发理论角度,分析了童氏图版的某些不合理之处;在水驱曲线理论推导的基础上,对童氏图版计算公式进行了改进和完善,拓宽了童氏图版的应用范围。实例应用表明,改进后的童氏图版对含水率与采出程度变化规律的描述更加符合实际,预测的采收率更准确。

Abstract: Tong's chart method is universally applied in prediction of field waterflooding recovery at home and abroad, but it is only usedin middle-late stage of oilfield development. For high viscosity reservoir with low waterflooding recovery and complex faulted-block oilfield with low permeability, Tong's chart is not used to describe real water cut and recovery percent. This paper presents analyses of some unreasonable problems in Tong's chart method from mathematics and reservoir development theory and improvements of its computing formulae, which widen its applied fields. The case study shows that modified Tong's chart is more reliable and accurate for description of regularity of varied water cut and recovery percent and for prediction of recovery efficiency.

Key words: oilfield development, water injection, water flooding, curve, recovery percent, water cut, chart
