摘要
埕岛油田CB30A 1井在四开钻进至 4 2 2 0 4 4m时发生井漏 (漏失速度达 4 8m3/h) ,随后发生井涌。采用无封堵钻井技术 ,顺利地完成了该井四开钻进任务。文中介绍了无封堵钻井工艺及其在CB30A 1井的应用情况。
In CB30A?1 well of Chengdao oilfield, a lost circulation occurred as the fourth spudding reached to the depth of 4?220.44 m,with the lost velocity up to 48 m3/h, and then a kick followed. But the fourth spudding has been completed because of applying the no_plugging drilling technology. This paper has presented the technology and its application in CB30A?1 well.
