【摘要】 油田注水管网系统属于大规模复杂流体网络系统。常规的系统模型计算方法需耗费大量的时间 ,它严重阻碍了注水系统仿真及优化技术研究的发展。通过研究和分析 ,提出一种改进的迭代计算方法 ,它避免了“0”元素的存储和计算 ,从而将计算工作量从二次方级降至一次方级。计算结果表明 ,在满足计算精度的前提下 ,系统模型的计算时间明显降低。目前 ,该项技术已应用于油田注水系统 ,结果令人满意。更多还原

【Abstract】 An oilfield water flooding pipeline network is a large-scale fluid network system.Conventional model calculation method consumes plentiful time and has seriously hindered the development of simulation and optimization of oilfield water flooding system.On the basis of analysis,an improved iteration method is given,which reduces the amount of calculation work from n 2 to n.The calculating result indicates that in the premise that the calculating accuracy is met,the model calculating time is reduced obviously.The technology has been used in oilfield flooding system and received satisfactory result.更多还原
