螺杆泵作为一种新的机械采油方式,目前已由实验型向生产型转变,如何最大限度的发挥螺杆泵井的优势,使其保持最佳的生产状态,是我们在生产过程中不断摸索的重点。本文首先通过对螺杆泵的工作特性曲线进行分析,对螺杆泵作为一种容积式泵,又兼具有离心泵的工作特性有了一个初步的认识,了解了泵挂深度的高低对螺杆泵的容积效率有直接影响,通过对螺杆泵合理压头的确定,获得了有效举升压力与泵级数之间的关系,并计算出不同级数泵的有效举升压力,折算成深度,得到了不同级数的泵应下入的合理泵挂深度,对指导螺杆泵井的施工及分析有一定的借鉴作用,从而使其生产合理,工况最佳。
As a new mechanical oil recovery method, screw pump has now changed from experimental to production type. How to maximize the advantages of screw pump well to keep it in the best production state is our continuous exploration in the production process Focus. Firstly, through analyzing the working curve of the screw pump, we have got a preliminary understanding of the working characteristics of the screw pump as a positive displacement pump and a centrifugal pump, Volumetric efficiency has a direct impact on the screw pump through a reasonable pressure head to determine the effective lifting pressure and the relationship between the pump series, and calculate the different series pump effective lifting pressure, converted into depth, has been Different stages of the pump should be under the reasonable pump hanging depth, the guidance of the screw pump well construction and analysis of a certain reference, so that it produces a reasonable, best working conditions.
