Horizontal Well Drilling Technology in Shallow Heavy Oil Recovery in Block Puqian 12 of the Daqing Oilfield

  • 摘要: 为提高大庆油田葡浅12区块浅层稠油油藏的开发效益,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口浅层稠油水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5 d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。
    Abstract: In order to improve the development of heavy oil in the shallow formations of the Daqing Oilfield and to reduce drilling costs, research on horizontal well drilling techniques for recovering heavy oil from shallow formations was carried out.A seven-section constant curvature design method was adopted and the optimum wellbore trajectory was determined.The technical measures during drilling were made.Casing programs and BHAs of different spuds were designed reasonably based on capability analysis through the string and necessary sealing point.These techniques have been applied in 3 wells of Block Puqian 12.Drilling time was reduced by 5 days compared with similar shallow formation heavy oil horizontal wells in the country.The result showed that horizontal well drilling techniques for ultra-shallow heavy oil reservoirs can solve the problems of shallow kick off points, sand running and casing running.This provided some technical measures in improving the development and the recovery rate of shallow heavy oil reservoirs with horizontal wells.
