During the modelling for optimizing the production parameters of progressive cavity pump wells using the nodal system analysis,both discharge port pressure and suction pressure need to be calculated in order to further choose progressive cavity pump and design rods according to pressure difference.

在采用节点系统分析方法优化设计地面驱动单螺杆泵采油系统所建立的模型中,需要求得螺杆泵吸入口和排出口压力,以便根据压差重新选择螺杆泵和设计抽油杆柱。
