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 .
In order to determine the economy of oil reservoir co-production, from the aspect of economic evaluation, the oil layers are classified, and the methods of determining the investment, cost and income of different types of oil reservoirs in the integrated production plan are studied. Sensitivity analysis model and a computer program block diagram of the evaluation process and the critical rate of change of the determination factor of the joint production plan is designed.The realization of this method can provide the basis for the decision-making of the oilfield development.
