胜利油田分公司桩西采油厂主要上产阵地和新建产能块主要分布在滩海地区,目前采油厂生产井中斜井比例越来越大,且井斜角大(大于65°),造斜点高(在190-500m左右),易出现杆管磨损严重、检泵周期短、泵效低等问题。偏磨井治理工作主要以斜井防偏磨为主,同时,兼顾直井深抽偏磨现象及井液腐蚀偏磨现象的治理。根据油井的具体偏磨情况,制订了多种防偏磨治理模式,采用尼龙扶正器、抗磨副、连续杆、内衬油管的分级治理方式。目前共治理偏磨井217井次,平均检泵周期延长96天,取得较好经济和社会效益。
The main production base and new production block of the pile oil production plant in Shengli Oilfield Branch are mainly located in the beach area. At present, the proportion of inclined shafts in the production wells of the oil production plant is more and more large with large inclination (greater than 65 °) High (about 190-500m), prone to serious wear of the rod, check the pump cycle is short, low pump efficiency and other issues. Offset well management is mainly inclined well anti-eccentric wear-based, at the same time, take into account the vertical well deep eccentric wear phenomena and well fluid corrosion partial wear governance. According to the specific partial well conditions, developed a variety of anti-wear management mode, the use of nylon centralizer, anti-wear Vice, continuous rod, lined with oil pipe hierarchical management. At present, a total of 217 wells have been treated for partial wear wells, and the average inspection pump cycle has been extended for 96 days to achieve better economic and social benefits.
