在抽油机井采油过程中,抽油杆与油管偏磨的现象已经成为影响油田正常生产的重要因素之一。近几年来,胜利油田针对偏磨现象虽然已经采取一些办法,取得一定成效,但尚未真正解决这一难题,而且有的油井还较为严重。生产过程中,抽油杆与油管偏磨的现象不仅损坏装置设备,减少了油井生产时率,同时还降低产油量,增加采油成本。因而有必要在不断实践中进一步加强对偏磨井分析研究,以便采取新科技和工艺有效治理,保证油井的正常生产。 During the process of oil well drilling, the phenomenon that sucker rod and oil pipe are partial wear has become one of the important factors that affect the normal production of oilfield. In recent years, Shengli Oilfield has adopted some measures for the phenomenon of partial wear and achieved some success, but it has not really solved this problem, but some oil wells are still more serious. During the production process, the phenomenon that the sucker rod and the tubing are eccentric worn not only damages the equipment and equipment, reduces the production rate of the oil well, but also reduces the oil yield and increases the oil recovery cost. Therefore, it is necessary to further strengthen the analysis of partial well in continuous practice in order to adopt new technologies and processes to effectively manage to ensure the normal production of the well.
