2014年7月16日,渤海钻探钻井一公司C15623侧钻队在大港油田女S67-43K井中,成功应用中国石油钻井工程技术研究院研制的连续油管钻机进行开窗作业,填补了一项国内空白。连续油管又称挠性油管,无接头、高强度、高韧性,具有安全、高效、环保等优势。与常规钻井相比,连续油管作业不需要接钻杆、起下钻,能够提高生产时效、降低施工成本。在深井、复杂结构井、欠平衡钻井中,连续油管钻井可以保持井底压
On July 16, 2014, C15623 side driller of Bohai Drilling & Drilling Company 1 successfully applied the coiled tubing drilling rig developed by China Petroleum Drilling Engineering Research Institute to open the window in female S67-43K well of Dagang Oilfield, which filled a gap in domestic market . Coiled tubing, also known as flexible tubing, without joints, high strength, high toughness, with safety, efficiency, environmental protection and other advantages. Compared with conventional drilling, coiled tubing operations do not need to take the drill pipe, drill down, can improve production aging and reduce construction costs. In deep wells, complex structural wells, underbalanced drilling, coiled tubing drilling can maintain bottom hole pressure
