【摘要】：随着我国经济的迅速发展，能源消费和石油对外依存度也日益增加。在没有找到能替代石油的新资源前，石油仍是全球的最主要能源。在这样的背景下，更应该重视现有的石油资源，努力提高油田开发效果，对油田开发规划进行优化研究。这不仅是保障国家石油安全的需要，也是油田开发企业提高经济效益的需要。论文以新疆油田开发现状和开发优化的相关理论为基础，运用动态规划方法对新疆油田开发规划进行优化研究。首先，根据指标选取原则，进行选取指标。依据模型中的各个参数，确定状态变量、决策变量、状态转移方程和目标函数，构建出动态规划优化模型，然后对优化模型给出3种不同解法。基于优化后的钻井数目，推出每年的动用地质储量、原油产量和新建产能。最后以新疆地区南缘油区进行实例分析，运用Visual C++求解优化模型，，得出每年新钻钻井数目、净现金流量和累计净现金流量。优化模型确保了方案实施后风险低、效益高，达到以尽可能少的投入获得最多的累计净现金流量的目的。论文在研究中克服了油价不稳定、新井老井区别和模型选择的困难。并将优化模型应用到新疆油田南缘油区的开发规划中，实现了理论到实践的过渡，达到了优化的目的。因此，上述研究具有一定的理论价值和重要的现实意义。
[Abstract]:With the rapid development of China's economy, energy consumption and oil dependence are increasing day by day. Until new sources of alternative oil are found, oil remains the world's leading energy source. In this context, we should pay more attention to the existing oil resources, strive to improve the oil field development effect, and optimize the oilfield development planning. This is not only the need to ensure the national oil security, but also the need for oil field development enterprises to improve economic benefits. Based on the current situation of oilfield development in Xinjiang and the related theories of development optimization, the dynamic programming method is used to optimize the development planning of Xinjiang oilfield. First of all, according to the principle of index selection, the selection of indicators. According to the parameters of the model, the state variables, the decision variables, the state transfer equations and the objective functions are determined, and the dynamic programming optimization model is constructed, and three different solutions to the optimization model are given. Based on optimized drilling numbers, annual production reserves, crude oil production and new production capacity are derived. Finally, taking the southern margin oil area of Xinjiang as an example, using Visual C to solve the optimization model, the number of new drilling wells, the net cash flow and the cumulative net cash flow are obtained every year. The optimization model ensures the low risk and high benefit after the implementation of the scheme, and achieves the goal of obtaining the maximum cumulative net cash flow with as little investment as possible. The paper overcomes the difficulty of oil price instability, the difference between new well and old well and the choice of model. The optimization model is applied to the development planning of the southern edge of Xinjiang oilfield, which realizes the transition from theory to practice and achieves the purpose of optimization. Therefore, the above research has certain theoretical value and important practical significance.
