中国石油集团渤海钻探工程有限公司工程技术研究院为满足复杂油气藏钻井完井对特殊完井管串及完井工具的需要,经过多年努力,研发了全通径系列尾管悬挂器及系列配套完井工具。该套设备具有设计先进合理、承载能力大、性能可靠稳定、现场操作方便、碰压成功率高、施工完成后实现全通径免钻塞、施工成功率高等特点,能够满足各种常规井、复杂井和特殊井尾管固井施工需要。文章重点介绍了该全通径系列尾管悬挂器的结构原理、技术参数、特点,并对现场推广应用情况进行了简要介绍。
CNPC Bohai Drilling Engineering Co., Ltd. Engineering Institute to meet the complex well drilling and completion of special completion string and completion tools needs, after years of efforts, developed a full-bore series of tail pipe hanger and series of supporting Completion tools. This set of equipment has the characteristics of advanced design and reasonable, large carrying capacity, reliable and stable performance, convenient operation on site and high success rate of impressing, full-bore free drilling after construction completion and high success rate of construction, etc. It can meet all kinds of conventional well, Complex wells and special well tailings cementing construction needs. This article mainly introduces the structure principle, technical parameters and features of this full-bore series tail pipe hanger and gives a brief introduction of its application in the field.
