摘要
以新疆油田分公司采油一厂稠油水平井为研究对象,针对在生产过程中频频出现杆断脱及偏磨现象,进行了一系列的理论分析。在理论分析的基础上,采用半圆对接式光杆、防脱抽油杆、防脱加重抽油杆、防偏磨扶正装置、低摩阻防气式注采抽油泵等防偏磨防断脱设备、工具,有针对性地对稠油水平井的下泵完井杆柱进行优化,使稠油水平井的开采得以正常进行,解决了长期困扰稠油水平井开采的断脱、偏磨问题,延长了检泵周期,对采油一厂稠油水平井的开采具有很高的现场应用价值。
Horizontal wells of heavy oil of Xinjiang oilfield branch production factory as the research object are taken. The prevention deflection wear and break off tools design of the semicircular - polished rod, preventer pump rod,preventer heavier rod, injection pump of lower friction and prevent gas, lower-frictionl gas -sucker pump. aiming at the phenomenon that rod frequently breaked off and partial grinded in the production process, conducted a series of theoretical analysis, on the basis of theoretical analysis, optimized tangibly the horizontal well under heavy oil pump well completion pole. The exploitation of horizontal wells of heavy oil are maken to be normal, solved the breaking off and partial grinding problem of horizontal wells of heavy oil exploitation, extended the overhaul period of pump, which has the very high field application value to heavy oil production factory of horizontal well drilling.
