| 摘 要： | 针对海上低渗油藏注气方案设计受平台环境、油藏特征和工艺条件等众多因素影响而复杂烦琐的问题，将响 应面方法引入水气交替驱方案的设计中。在确定了少量但具有代表性的气驱方案的基础上，通过对其结果的统计分 析，形成了采收率指标与注气时机、水气比、周期注入段塞3 个因素之间的预测模型与响应曲面，并在此基础上开展了 注气参数优化设计。通过该方法可以对研究范围内的气驱方案进行高效地设计、预测和优化，简洁、直观地确定最佳 气驱方案，科学、高效地实现设计目标，提高了海上低渗油藏气驱设计工作的效率和质量。 |
| 关 键 词： | 海上低渗 注气 提高采收率 响应面 |

| Abstract: | Aimed at the gas injection scheme design influenced by the reservoir characteristics，platform environment and process conditions in offshore tight reservoirs，and so on，the response surface method“D – Optimal”is introduced to the design of the WAG flooding process. Based on the representative gas flooding scheme and the statistics analysis of their results，the prediction models and response surface for the recovery ratio index and gas injection time，water/gas ratio，cycle injection plugins were presented，and the optimization design of the gas flooding parameters was investigated. The results show that the work efficiency and quality of the low permeability reservoir gas flooding design in offshore has been improved. |
| Keywords: | offshore tight reservoir WAG EOR response surface |
