应用数值抽象地质模型及相应的油层物性参数＋油藏数值模拟＋油藏工程＋数理统计的方法，研制和建立了《河流相注水多层油藏平面波及评价与挖潜宏观决策系统》（简称“评价与决策系统”）。应用这一系统，可以评价河流相注水多层油藏在不同综合含水下的分油砂体的含水率、平面波及系数以及由于边角、井网不完善、低渗透等3个因素影响的平面未波及系数（即平面未波及剩余油），据此可提出分油砂体的挖潜措施。这一系统也编制了相应的计算机程序。港西4区明Ⅲ2。油藏的计算实例表明了这一“评价与决策系统”在油田剩余油研究与开发调整中的重大价值。
The numerical abstract geological model and corresponding reservoir physical property parameters + reservoir numerical simulation + reservoir engineering + mathematical statistics method were used to develop and establish the macro-decision-making system of plane wave evaluation and tapping potential in multi-reservoir river fluvial waterflooding (referred to as “ Evaluation and decision-making system ”). By using this system, it is possible to evaluate the water cutoff, plane wave propagation coefficient and the plane affected by three factors such as corner, well pattern and low permeability in multi-reservoir reservoirs of river facies injection under different comprehensive aquifers. Did not affect the coefficient (that is, the plane does not affect the remaining oil), which can be based on sub-submarine sand body potential measures. The system also compiles the corresponding computer program. Hong Kong West 4 area Ming Ⅲ2. The reservoir calculation shows the great value of this “evaluation and decision-making system” in the research and development and adjustment of remaining oil in the field.
