在实际工作中得到的经验而知,在油田的作业工作中由于作业量大、抽油环境有高压、压力大等特点,抽油设备长时间地连续作业,其抽油杆在持续的力的作用下难免会产生磨损和变形,其中以抽油杆发生偏磨现象产生的问题最为突出。在这种情况下,抽油杆由于偏磨现象的产生,抽油杆与抽油壁之间的摩擦力增加,而收缩回来时的压力负荷值也明显增加,这样就导致机器运转的实际功率变大,进而导致工作效率的降低。
Experience gained in the actual work shows that in the oilfield operations due to the large amount of work, the pumping environment has high pressure, pressure and other characteristics, pumping equipment for a long time continuous operation, the sucker rod in the sustained force Under the action will inevitably produce wear and deformation, in which sucker rod eccentric wear phenomenon most prominent. In this case, the sucker rod due to partial wear phenomenon, the sucker rod and the pumping wall between the friction increases, and shrink back pressure load value is also significantly increased, thus resulting in the actual operation of the machine power Become larger, which in turn leads to lower work efficiency.
