2、藏的开发效益,降低钻井成本,开展了浅层稠油水平井钻井技术研究。在分析主要钻井技术难点的基础上,根据地层特点优选了地质靶点,采用了7段制井眼轨道设计,并根据管柱下入能力分析结果,考虑必封点确定了井身结构和各开次的钻具组合,并制定了钻进技术措施,形成适合葡浅12区块的浅层稠油水平井钻井技术。该技术在3口浅层稠油抽平井进行了成功应用,与国内其他浅层稠油水平井相比,钻井周期缩短5d以上。这表明,超浅稠油水平井钻井技术能解决葡浅12区块浅层稠油水平井造斜点浅、流沙层不易造斜、管柱下入难度大等问题,为利用水平
3、井开发浅层稠油油藏、提高采收率和开发效益提供了技术支持。关键词:浅层稠油油藏水平井钻井设计井身结构钻具组合大庆油田中图分类号:TE243。。.1文献标识码:A文章编号:1001—0890(2015)01—0126—05HorizontalWellDrillingTechnologyinShallowHeavyOilRecoveryinBlockPuqian12oftheDaqingOilfieldChenShaoyun,LiAihui。,LiRuiying,WangChu,LiuJinwei(1.
