在原油价格较低的情况下。化学驱油主要的问题是降低成本。在美国采用化学驱油方法提高原油产量的主要对象是轻质油油田。进行了与经济模型相结合使用模拟的结果来优选表面活性剂和聚合物化学驱油的设计。不同的表面活性剂浓度对工程效益有显著的影响。最理想的结果是聚合物和表面活性剂二者是低浓度并同时注进油层。有时选用低张力聚合物。设计的敏感性分析表明，最重要的经济变量是油价。折扣率。经营费用和化学制剂的价格。在敏感性分析中，也包括了不同聚合物的浓度，油田的实际渗透率和垂直与水平渗透率的比率。蒙特卡伦模拟就是用作对表面活性剂／聚合的注水风险评估的演示。结论表明，应用实际的油藏模拟与现代工艺技术（如水平井积最优化经济评价法，是能改进化学注水工程的设计。
In the case of lower crude oil prices. The main problem with chemical flooding is reducing costs. The main target of using chemical flooding to increase crude oil production in the United States is light oil fields. The use of simulation results in combination with economic models was conducted to optimize the design of surfactants and polymer chemical flooding. Different surfactant concentrations have a significant impact on engineering benefits. The best result is that both the polymer and the surfactant are at a low concentration and injected into the reservoir at the same time. Sometimes use low-tension polymer. The sensitivity analysis of the design shows that the most important economic variable is oil price. Discount Rate. Operating expenses and chemical prices. Sensitivity analysis also includes the concentration of different polymers, the actual oil field permeability, and the ratio of vertical to horizontal permeability. The Monte Carlo simulation is a demonstration used to assess the risk of flooding surfactant / polymerizations. The conclusion shows that the application of actual reservoir simulation and modern technology, such as the economic evaluation of horizontal well product optimization, can improve the design of chemical flooding projects.
