2、高压地层、并壁易失稳、易并斜等技术难点,提高钻井速度,加快勘探进程,开展了钻井提速技术研究。针对地层特征和钻井技术难点,进行了井身结构优化设计、并位预移+方向造斜技术、古近系深层个性化PDC钻头设计与优选、简易控压钻井技术和聚胺KCl钻井液技术的研究,形成了钻井提速综合配套技术。阳探1井顺利达到钻探目的层,三开段平均井径扩大率仅为1.8,与邻井相比,复杂时效由5.4降为0,平均机械钻速提高了39.86,钻井周期缩短了4O。2O,建井周期缩短了44.19,提速效果突出。研究结果表明,深潜山阳探1井钻井提速技术是实现饶阳凹陷
3、深潜山井优快钻井的有效技术手段,可进一步推广应用。关键词:深井钻井提速井身结构PDC钻头阳探l井饶阳凹陷中图分类号:TE249文献标志码:A文章编号:1001—0890(2015)06—0130—05ROPImprovementTechniquesAppliedinWellYangtan1whenDrillingintoaDeepBuriedHillLuoYucai,LiJingying~,LiZhenhao。,WangDongming,ChengXiaodong(1.ExplorationDepartment,Petr
