页岩气"井工厂"钻井技术现状及展望

Status and Prospect of Multi-Well Pad Drilling Technology in Shale Gas

  • 摘要: "井工厂"技术可以缩短建井周期,降低钻井成本,大幅度提高资源及设备利用率,在页岩气等低渗透、低品位非常规油气资源开发中具有显著的技术优势,并在北美页岩气开发中获得成功应用。在国外文献调研的基础上,介绍了国内外"井工厂"钻井技术现状,详细分析了页岩气"井工厂"关键技术,总结了"井工厂"钻井技术的特点,并指出国内现有的技术储备、配套设备及工具等还不能完全满足"井工厂"作业的需求,还没有形成一套完整的"井工厂"施工及评价标准。因此,建议树立全过程成本控制理念,吸收我国海洋平台钻井技术和致密气藏"井工厂"开发模式的成功经验,针对性地开展个性化工具及配套技术的研发,尽快形成我国页岩气"井工厂"钻井技术的行业标准和钻后评价体系。

     

    Abstract: Multi-well pad drilling can shorten well construction period,reduce drilling cost and substantially improve the utilization rate of resources and equipment.It has obvious technical advantages especially in the development of shale gas,a typical unconventional resources of low abundance and low grade,and has gained popularities in North America.In order to use multi-well pad techniques in China’s shale gas development as soon as possible,this paper introduced the multi-well pad drilling status worldwide,analyzed key factors influencing multi-well pad techniques’ implementation,and systematically summarized the characteristics of multi-well pad drilling.It indicates that the existing techniques,supporting facilities and downhole tools can not completely meet the demand of multi-well pad operation,and well pad operation and evaluation standards have not been defined.Therefore,it was recommended that the whole process of cost control concept should be set up,and the successful experiences in offshore drilling and tight gas reservoir factory development mode should be adapted.Meanwhile,research on specified tools and supporting techniques should be done,and well pad drilling operation standards and post drilling evaluation system should be set up.
