区块整体调剖优化设计技术研究

为满足区块整体调剖技术优化设计的需要，研制开发了一套简便、适用的区块整体调剖优化决策系统，采用模糊综合评判技术建立调剖井选择优化模型、以反映注水井注水能力及油藏和流体特征参数筛选调剖剂，用井组数值模拟优化调剖剂用量和预测调剖效果。采用该方法既可加快计算速度、满足现场调剖的急需，又可保持数值模拟计算在效果预测方面的准确性。利用该方法对辽河油田龙11块整体调剖进行了优化设计，现场试验结果和预测结果相符，取得了较好的增油降水效果。图4表1参2（白宝君摘）

The optimization technology of block-wide injection profile control

To optimize block-wide injection profile control, this paper studies a set of simple, applicable optimum design methods. This set of methods is ready to select well,layer and agent,and to optimize volume adn injection paramters. The fuzzy mathematic method is used to select well. Many parameters, such as injection ability of injector, pH and salinity, are considered to select chemical agent. Volume optimization model is based on well group numerical simulation.The main factors influencing plugging agent volume are considered,and these factors include the destination of profile control, variable factor of permeability, water cut of production well, recovery,formation thickness, water injection volume, oil and water relative permeability curve, oil viscosity, Kv/Kh and fr. This technlogy was applied in Long 11 block, Liaohe oil field. After operation, oil rate was increased, water rate was reduced and oil recovery was also improved.
