Tungsten alloy sucker rod has small flow channel and fast flow rate, which is not easy to deposit sand grains and suitable for oil Wells containing sand. It can also be used in conjunction with a pipeless pump to allow oil to flow out of the inner hole of the hollow sucker rod. Because its torsional resistance is greater than that of ordinary sucker rod, it is suitable for driving downhole screw sucker pump and is convenient for installing various controllers into the well. It is important to note that, in order for the sucker rod to work safely, as the well depth increases, sucker rods of different diameters should be selected, that is, multi-stage sucker rod.
