油田高含水期稳产措施配置多层目标规划

措施规划对于延长油田稳产年限 ,提高采油速度及提高最终采收率是十分必要的 .有些学者建立了油田稳产措施规划的整体或区块规划模型 ,但没有考虑实际油田生产各生产层系的地质特性和所采取措施的差别 .本文针对油田开发实际中存在多层现象 ,以区块的各个生产层为基础 ,建立了油田措施的多层目标规划模型 ,并采用合理的算法进行求解 .应用结果表明 ,多层目标规划使措施配置更精细 ,更能反映生产实际 ,是解决油田措施配置问题的一项有力工具

THE MULTI-LAYER OBJECTIVE PROGRAN MODEL FOR MEASURE PLANNING OF OIL FIELD

measure programming is very essential to extend the time limit of stable production,to plan reasonable measures to oil field to enhance the oil recovery rate and the final recovery.Some models have been established on the programming of oilfield production stabilizing measures,which based on one whole oilfield(not concerning multi multiple layers).In fact,many multilayer oilfields become more sophisticated by the differences of geologic properties and engineering measures taken to among layers.In This paper ,the multi layer objective model has been constructed for the measure programming based on the material every layers.The model can be efficaciously solved with the genetic algorithm,which has the characteristic of whole area searching and highly effective.The method has been applied to the practical oil field and shows that the multi layer programming model is a very efficient to make oilfield development plan and can be used as a powerful tool.
