摘要： 童宪章院士于1978年提出的确定水驱油藏采收率的图版法，被我国1989年、1998年和2010年发布的石油天然气行业国家标准所引用，并定名为童宪章图版法。该图版具有直观、简明和易用的特点，深受广大油藏工程师的重视。然而，由于童氏图版制作是以极限含水率98%为基础，在实际应用时会受到一定限制，并会导致预测采收率的不确定性。在研究童氏图版的基础上，提出了广义童氏图版关系式，建立了不同极限含水率的图版。通过含水率的拟合确定水驱油田的采收率，进而确定油田的可采储量。实例应用表明，广义童氏图版是实用有效的。

Abstract: In 1978, Academician Tong Xianzhang proposed the chart method for determination of water drive recoverable reserves based on Type A water drive curve. This chart was cited by the national standards of petroleum industry published in 1989, 1998 and 2010 in China. For the chart is intuitive, simple and applicable, it is very popular and highly regarded by all reservoir engineers. However, it was restricted in application and resulted in uncertainties because the chart was made based on water cut limit of 98%. In this paper, the generalized Tong’s chart is established based on Tong’s work. The generalized chart can not only expand in application range, but also improve reliability for forecasting recovery efficiency. Using the matching water cut with Tong’s chart, the recovery factor and the recoverable reserves can be determined. The field application shows the generalized chart is effective and practical
