有杆抽油系统工况分析（Analysis of working condition of rod pumping system）

有杆抽油系统工况分析（Analysis of working condition of rod pumping system） Analysis of working condition of rod pumping system The analysis of the oil well production purpose is to know the reservoir production capacity, equipment capability and their working conditions, in order to further provide evidence for reasonable technical measures, make the equipment capacity and reservoir ability, give full play to the reservoir potential, and make the equipment working under high efficiency, to ensure a high production, high pump efficiency of production. To this end, the oil well analysis should include the following: (1) to understand the production capacity and working conditions of the oil layer, analyze whether the potential of the reservoir has been played out, and analyze and judge the reasons for the abnormal work of the oil layer. (2) understand the equipment capability and working conditions, analyze the equipments ability to adapt to the production capacity of oil layers, understand the potential of the equipment, analyze and judge the reasons for the abnormal equipment. (3) analyze the effect of inspection measures. Generally speaking, the analysis of the working conditions of rod pumping system is to analyze the working condition of the oil layer and the working condition of the equipment, and the coordination between them. I. test and analysis of oil well level (1) hydrostatic surface, liquid surface and oil production index Static liquid surface is to restore the liquid level in the annular space after shut-in static, formation pressure and phase equilibrium of liquid surface, can be used from the well depth Ls said its position, can also use from central reservoir liquid level height Hs to indicate its position. The pressure of the bottom hole corresponding to it is reservoir pressure. The liquid surface is the liquid surface of the oil jacket ring space when the oil well is produced. The depth Lf can be used from the wellhead to indicate its position, and it can be
