大泵抽油是在有杆泵抽油井中加大油液量的有效方法。所谓大泵是指抽油泵的直径大于55毫米,即包括新系列抽油泵标准的φ55、φ70、φ83和φ95四种尺寸。从我国油田的实际来看,在高含水量的停喷井和抽油井中动液面一般都较高,也就是说从动液面到井口的距离即举液高度一般都不大。如果按举液高度来划分油井的话,这类井是属于浅井(举液高度低于
Large pumping oil pumping rod in the oil well is an effective way to increase the amount of oil. The so-called large pump refers to the pump diameter greater than 55 mm, which includes the new series of pump standard φ55, φ70, φ83 and φ95 four sizes. From the actual situation in China’s oilfield, the high water cut-off wells and pumping wells are generally higher in the level of liquid, that is to say, the distance from the driven surface to the wellhead that is, liquid height is generally not large. If according to the height of fluid to divide the oil well, these wells belong to shallow wells
