经过长时间的发展,我国油田不断深化开采,许多油田油井已进入大规模注水的发展阶段,大规模注水也带来了更高的能耗,这种发展条件下,对注水管网初期布局设计的合理性和水力计算的可靠性的要求也就越来越高。简要介绍了油田环状注水管网的仿真计算方法,针对各计算方法分别列出了详细的计算步骤,并分析了其适应条件及各自优缺点。 After a long period of development, China’s oilfields continue to deepen the exploitation of oilfields. Many oilfield wells have entered the stage of large-scale waterflooding. Large-scale waterflooding has also led to higher energy consumption. Under these conditions, initial layout design of waterflooding pipe networks The rationality of hydraulic calculation and the reliability of the request is higher and higher. The simulation calculation method of annular injection pipe network in oilfield is briefly introduced. Detailed calculation steps are listed separately for each calculation method, and their adaptability conditions and their respective advantages and disadvantages are analyzed.
