针对纯梁油田的油井偏磨严重,导致杆管的大量报废,作业费用居高不下,制约油井免修期延长,影响油田开发水平提高。文章介绍调弯防脱扶正器的设计原理及在井下生产模拟状况,现场应用中取得了好的防偏磨效果。 For pure beam field oil well eccentric wear and tear, resulting in a large number of pole tube scrapped, high operating costs, restricting the extension of oil wells exemption period, affecting the development of oil fields to raise the level. The article introduces the design principle of the buckling stabilizer and the simulation of the production in the underground. The field application has achieved good anti-wear effect.
