在油田开发规划中,需要确定产量目标以及产量构成,即自然递减产量、措施产量、老区新井产量、新区新井产量和三次采油产量等.根据油田开发规划的需求,以经济效益为中心,分别以总成本最低、产量最大、利润最大为目标函数,建立了油田开发规划模型和各油区优化配产和投资模型,给出了相应的非线性求解方法.冀东油田的应用结果表明:原规划结果措施产量为0.30×106t,新井产量为0.82×106t,优化结果措施产量为0.37×106t,新井产量为0.75×106t,需要在原规划的基础上上调措施产量,下调新井产量.该模型可为油气田的规划和投资提供定量决策的方法,可用于规划计划的编制,以及资源、产量和效益优化的配置.
In oilfield development planning, it is necessary to determine the production target and output composition, that is, natural decreasing production, measure output, new old well production, new well production and tertiary oil production in New District, etc. According to the demand of oilfield development planning and economic benefits, The lowest total cost, the largest output and the highest profit as the objective function, the oilfield development planning model and optimization allocation and investment model of each oil region are established and the corresponding nonlinear solution methods are given.The application results of Jidong Oilfield show that the original planning The results show that the yield of the measures is 0.30 × 106t, the productivity of new wells is 0.82 × 106t, the yield of optimized result measures is 0.37 × 106t, and the productivity of new wells is 0.75 × 106t, which needs to increase the output of measures and decrease the production of new wells on the basis of the original plan. Planning and investment Quantitative decision-making methods can be used for the planning of the planning, as well as resources, production and efficiency optimization configuration.
