摘　　要：目前,哈萨克斯坦共和国让纳若尔油田部分老井经过多年的开采后产量很低或已无产量,但井间还有较多的剩余油并没有采出。因此,在调研国内外开窗侧钻井技术的基础上,结合油田的前期侧钻经验、地质特征、技术难点等,在现有装备和条件下实现了针对Φ139.7 mm小井眼开窗侧钻井的技术改造和钻井提速,有效延长了让纳若尔油田低产量老井的采油寿命,降低了综合开发成本。At present,the production of some old wells in the jannaroer oilfield of the Republic of Kazakhstan is very low or has no production after many years of exploitation,but there is still a lot of residual oil between the wells.Therefore,based on the investigation of sidetracking technology at home and abroad,combined with the previous sidetracking experience,geologi⁃cal characteristics and technical difficulties of the oilfield,under the existing equipment and conditions,the technical transfor⁃mation and drilling speed increase ofΦ139.7mm slim hole sidetracking are realized,which effectively prolongs the oil recov⁃ery life of the low production old wells in channaroer oilfield and reduces the comprehensive development cost.
