【摘要】：辽河油田茨榆坨采油厂由于注水区块多,地质情况复杂,对注水地面管网系统的运行目前还缺少即时可靠的动态分析方法。开展油田注水地面管网系统运行参数优化研究,对于辽河油田茨榆坨采油厂注水地面管网系统的动态跟踪、高效运行、节能降耗无疑具有重要意义。本文根据物质守恒原理及流体力学理论,在完善了油田注水地面管网系统运行参数计算数学模型的基础上,以油田注水地面管网系统单耗为目标函数,以油田注水地面管网系统设计注水参数为约束条件,建立了油田注水地面管网系统运行参数优化数学模型,并给出了相应的数值计算方法;由上述数学模型及相应的数值计算方法,应用Visual Basic 6.0及Excel数据库编制了“辽河油田茨榆坨采油厂注水地面管网系统运行参数优化”程序,并据其对辽河油田茨榆坨采油厂注水地面管网系统井口压力、管网管线流量、流速、压降、泵的运行工况、注水地面管网系统效率、单耗进行了数值计算与分析,并得到了优化的注水站泵排量。上述研究成果可为辽河油田茨榆坨采油厂注水地面管网系统的节能降耗提供可靠的理论和技术支撑。
[Abstract]:Due to the large number of water injection blocks and complicated geological conditions, the operation of water injection surface pipe network system in Liaohe Oilfield is still short of reliable dynamic analysis method. The optimization of operation parameters of surface water injection pipe network system in oil field is studied. It is of great significance for the dynamic tracking, efficient operation, energy saving and consumption reduction of the water injection surface pipe network system in the oil production plant of Liaohe Oilfield. This paper is based on the principle of material conservation and the theory of hydrodynamics. On the basis of perfecting the mathematical model of operation parameters calculation of oilfield water injection surface pipe network system, the unit consumption of oilfield water injection surface pipe network system is taken as the objective function, and the design water injection parameter of oilfield water injection surface pipe network system is taken as the constraint condition. A mathematical model for optimizing operation parameters of oilfield water injection pipeline network system is established, and the corresponding numerical calculation method is given, and the above mathematical model and corresponding numerical calculation method are given. Based on Visual Basic 6.0 and Excel database, the program of "optimization of operation parameters of water injection surface pipe network system in Cishutuo Oil production Plant of Liaohe Oilfield" is compiled. According to the program, the wellhead pressure and pipeline flow rate of water injection surface pipe network system in Tsiyutuo Oil production Plant of Liaohe Oilfield are analyzed. The flow rate, pressure drop, pump operating condition, water injection surface pipe network system efficiency and unit consumption are numerically calculated and analyzed. The above research results can provide reliable theoretical and technical support for the energy saving and consumption reduction of the water injection surface pipe network system in the Zi-yutuo Oil production Plant of Liaohe Oilfield.
