开采低产能、高油气比的油气井时,应用柱塞举升是目前最优的选择,主要是因为柱塞举升具有投资成本较低、设备构造简单以及运费费用较少等优点。在柱塞举升的实际应用过程中,需要在现场经过反复地调试才能够确定所需要的具体工况参数,尤其是在油气井生产控制的自动化趋势不断加强的今天,工况参数调试的问题更加突出。在本文中,笔者结合大庆油田的实际情况,利用节点系统分析方法对柱塞举升进行优化设计,并探讨了塞举升影响因素敏感性问题。 Plunger lift is the optimal choice for the production of low-productivity, high-oil-gas wells. The main reason is that plunger lift has the advantages of lower investment cost, simple equipment structure and less freight costs. In the actual application process of plunger lift, it needs to be debugged repeatedly in the field to determine the specific working condition parameters needed. Especially in the automation trend of production and control of oil and gas wells, the debugging of working condition parameters More prominent. In this paper, combined with the actual situation of Daqing Oilfield, the author uses node system analysis method to optimize the design of plunger lift, and discusses the sensitivity of plug lift impact.
