油田环状注水管网水力仿真计算综述

Hydraulic Simulation Calculation of Annular Water Injection Pipeline Network in Oilfields

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。

With deep development of oilfields in China, many oilfields have enter large-scale water injection development stage, the large-scale water injection brings high energy consumption problem. Under the development condition, the requirements for the rationality of initial water injection pipe network layout design and the reliability of hydraulic calculation are higher and higher. In this paper, simulation calculation methods of annular water injection pipe network in oilfields were introduced. Aiming at different calculation methods, their calculation steps were listed. Adaptation conditions of these methods were analyzed as well as their advantages and disadvantages.
