我国正面临两个根本转变，石油工业确立了以经济效益为中心，加快发展的基本思路。提高油田开发的经济效益是极其重要的课题。文中以我国后期开发油田为研究对象，从分析影响经济寿命的因素入手，提出了经济寿命的计算方法，并首次采用系统集成建模与仿真思想，建立了能反映后期开发油田生产规律的技术经济指标预测模型、经济寿命计算模型、采炼一体化黑箱模型、成本动态控制模型、措施优化模型，同时还结合油田实际情况，提出了延长后期开发油田经济寿命和提高经济效益的对策。
Our country is facing two fundamental changes. The oil industry has established the basic idea of taking economic benefits as the center and accelerating development. Improving the economic benefits of oilfield development is an extremely important issue. Starting from analyzing the factors affecting the economic life, this paper puts forward the calculation method of economic life, and for the first time adopts the idea of system integration modeling and simulation to establish a technology economy that can reflect the law of oilfield production in the later stage. Index prediction model, economic life calculation model, integrated black-box mining model, dynamic cost control model and measure optimization model. Meanwhile, some countermeasures are put forward to extend the economic life of oilfields and increase economic benefits in the later stage.
