面向油层的合采方案经济评价

Layer-oriented economic evaluation of oil commingling

为了确定油层合采的经济性 ,从经济评价角度对油层分类 ,研究了合采方案中不同类型油层的投资、成本费用和收益的确定方法 ,给出了面向油层的合采方案经济评价模型和敏感性分析模型 ,并设计了合采方案的评价过程和确定因素临界变化率的计算机程序框图 .该方法的实现可为油田开发决策提供依据 .

For the sake of evaluating the economics of oil commingling, the paper classifies the oil layers from the viewpoint of economic evaluation, discusses the determining method of investment, cost and revenue of different kind of layer, put forward the layer\|oriented model of economic evaluation and sensitivity analysis of oil commingling, and sets up the procedure of economic evaluation and the flow chart of calculating the marginal value of factors for computer program. The Implement of this approach can provide a foundation for the decision making in oil development.
