摘要: 将平均含水饱和度与岩心出口端含水饱和度的不同函数关系式与Welge方程相结合,导出了目前国内注水油田开发评价和可采储量标定中最主要、最常用的4类水驱特征曲线——马克西莫夫-童宪章水驱特征曲线(甲型)、沙卓洛夫水驱特征曲线(乙型)、广义西帕切夫水驱特征曲线(广义丙型或卡札柯夫曲线)和广义纳扎洛夫水驱特征曲线(广义丁型或俞启泰曲线).为进一步揭示这些水驱特征曲线的油水两相渗流比值特征提供了理论依据.

Abstract: The average water saturation and the water saturation at exit end of core are the different functions.The Welge equation was combined with above functions to derivate the most primary and the common four types of water-drive characteristic curves during oilfield development.These characteristic curves were usually applied to appraisement of water-flooding oilfield development and determination of the recoverable reserves in domestic,including Maksimov-Tong Xian-zhang water-drive characteristic curve(first curve),В.Ф.Сазонов water-drive characteristic curve(second curve),generalized Н.В.Сипачев water-drive characteristic curve(generalized third curve or А.А.Казаков curve) and generalized С.Н.Назаров water-drive characteristic curve(generalized fourth curve or Yu Qitai curve).The study provided theoretical bases for further revealing the ratio of oil and water permeability in these water characteristic curves.

Key words: water drive characteristic curve, fluid percolation characteristic, Welge equation, water flooding oilfield development, reserves determination
