摘　　要：相关决策技术是利用油藏所有油水井生产参数相关关系的变化规律来反映油藏开发生产过程中的动态特征。将油藏作为一个整体 ,利用油水井生产参数的变化规律来建立若干个动态分析模型 ,进而评价油藏的开发效果。并且直接应用Oracle数据库的现有数据 ,使数据的来源准确可靠 ,并随着现场动态数据的更新而自动添加。通过对中原油田采油三厂马寨油田卫 95北块 3 2口油水井开发过程中的建模计算 ,结果与实际生产较吻合 ,符合率在 95 %以上 ,从而为油田下一步实施油水井措施、开发方案调整等决策提供科学的依据。The technique of correlation decision can reflect the behavior characteristics of reservoir development and production by use of the change rule of correlation of oil water wells production parameters We take the reservoir as a whole, and build several dynamic analysis models by the changed rule of oil water wells production parameters, then evaluate the effect of reservoir development Through models founding and calculation on 32 oil water wells which lie in Block 95, in Mazhai Oilfield, the obtained result coincided with the actual production The coincidence rate exceeded 95% This revealed low production level in the middle part of reservoir, weak strength of water drive and bad effect of water drive This also revealed that most of reservoir were not suitable for extraction liquid production, so it provided more scientific basis for the decision of adjustment of oil water wells development
