摘要
童氏图版是根据采出程度和最终采收率预测含水率的方法,但大多数的生产数据都无法将油藏开发全程的采出程度与含水率展布在一个图版上,实际应用受到限制.修正童氏图版是根据油田开采不同阶段（相同开采方式）的生产数据,经过分段回归分析,建立相应的数学预测模型,并计算采出程度、可采储量和采收率等开发指标.实例计算证明,修正童氏图版对含水率与采出程度变化规律的描述更符合实际,预测结果更准确.
Tong＇ s chart board is one of water-cut predicting methods by means of the recovery degree and ultimate recovery factor, but because most production data can not be spread and distributed on one chart board for all the recovery degrees and water cuts in the whole development course of the oil reservoirs, so they are limited in the practical application. Based on the production data from different stages of the oilfield development exploitation （ the same form of exploitation） , the corresponding mathematical predicting model is established with the help of the corrected Tong＇ s chart board and meanwhile the development indexes such as the recovery degree, recoverable reserves, recovery factor and so on are calculated. The practical calculation of the history case show that Tong＇ s chart board can more practically characterize the changed laws of the water cut and recovery degree and furthermore the predicted results are more accurate.
