措施规划对于合理制定油田稳产措施 ,延长稳产年限 ,提高最终采收率是十分必要的。有些学者建立了油田稳产的确定性规划 ,即规划模型中所有参数均为确定值 ,而实际油田生产中有许多不确定因素。本文针对这种现象 ,利用规划论中处理随机现象的机理 ,建立了油田措施的线性随机规划模型 ,并采用遗传算法进行求解。在大港官 10 4断块的稳产措施规划中得到了应用。结果表明 :线性随机规划数学模型更能反映生产实际 ,是解决油田措施规划问题的一项有力工具。
Measures for planning for the rational development of oilfield stability measures to extend the stability of life, improve the final recovery rate is very necessary. Some scholars have established a certainty of stable production in oilfields, that is, all the parameters in the planning model are definite values, but there are many uncertainties in the actual oilfield production. In view of this phenomenon, this paper uses the mechanism of dealing with stochastic phenomena in planning theory and establishes a linear stochastic programming model of oilfield measures, which is solved by genetic algorithm. It has been applied in the plan of stable production of Dagangguan 104 block. The results show that the mathematical model of linear stochastic programming can better reflect the actual production and is a powerful tool to solve the planning of oilfield measures.
