摘要： 在水驱油田开发实践中,国内外提出了大量的水驱特征曲线表达式,其中常见的有甲型、乙型和丙型水驱曲线等。但这些曲线存在在生产中后期发生上翘的现象,导致对于油藏可采储量的计算产生较大误差。针对这种现象提出了一套新型水驱特征曲线对油藏生产中后期的生产动态进行预测,这些曲线能够比较准确地计算出中后期的生产动态指标。对于某油藏实例进行计算的结果表明,提出的新型水驱曲线对于某水驱油藏而言比传统的水驱特征曲线计算结果更为准确。

Abstract: In practices of oil fields by waterflooding process, a great number of equations of the type-curves have been put forward, among which A, B and C type-curves are widely adopted. However, all these curves would warp upward in mid-late stage of production, resulting in significant differences in recoverable reserves calculation. In this paper, a new set of type-curves are proposed for prediction of the production performance of such a stage, which can be applied to more accurate estimation of the reserves. The case study indicates that the results from the new type-curves are more accurate than those from conventional curves.
