滨南平方王油田投入开发时间早,油、套管变形老化严重,尤其进几年来,随着斜井、侧钻井的逐年增加以及中、高含水期开采阶段的到来,平方王偏磨井逐渐增加。由于偏磨日趋严重造成作业频繁,免修期短。不仅对原油生产造成一定影响,而且造成作业费用超支,经济效益差。为此,研究偏磨原因,对偏磨井进行综合治理,是挖掘老油田潜力和提高采收率的重要手段,具有十分重要的意义。 Binnan Fangwang Oilfield put into development early, oil, casing aging serious deformation, especially into the past few years, with the inclined shaft, side-drilled year by year and the middle and high water cut period of the arrival, the square Wang partial wear well gradually increase. Due to the increasingly serious partial abrasion caused by frequent operations, maintenance-free period is short. Not only has a certain impact on the production of crude oil, but also lead to over-expenditure of operating costs, poor economic returns. Therefore, it is of great significance to study the reason of eccentric wear and comprehensively control the partial wear well, which is an important means to excavate the potential of the old oilfield and enhance oil recovery.
