摘要：根据普通稠油油田面积注水开发的特点，为了解决注水平面矛盾的问间题，基于流管法得到了注采单元面积波及系数、时间和含水率的计算公式，并成功运用到反九点并网，从数学理论上初步解决了两相驱替条件下面积波及系数的计算问题。研究结果表明，稠油油藏油并见水后，含水率迅建升高，面积波及系数增速减小；反九点井网边井和角并的见水时间和面积波及系数不同，需要采用不同的工作制度使水驱更加均匀；理论计算结果与数值模型计算结果一致。该方法为后续面积波及系数理论研究的开展提供理论基础。

Abstract: In terms of the characteristics of pattem flooding of conventional heavy oil reservoirs, to eliminate the problems related to water-flooding plane, stream-tube method has been used to develop equations for calculation of sweep efficiency, timing and watercut on unit area of flooding operations. These newly developed equations have been applied successfully in inverse 9-point patterm success-fully for the first time to calculate areal sweep efficiency under two-phase flooding theoretically. Research results show producers for heavy oil development may have quickly increasing watercut and rapidly decreasing areal sweep efficiency after water breakthrough Since wells on the boundary or comers of the inverse 9-point patterm may have different water breakthrough time and areal sweep ef-ficiencies, different flooding systems shall be deployed to achieve more evenly distributed water-flooding performances. Theoretical calculation results are consistent with numerical simulation conclusions. The innovative calculation methods may provide reliable theo-retical foundation for future studies for areal sweep efficiency.
