在小井眼开发早期,缺乏修井经验,增加了修井作业施工的难度和成本,针对小井眼井自身特点,我们对小井眼修井中出现较多的井下落物等事故进行整理分析和讨论,研究出一套成熟的针对小井眼修井中落物打捞的技术,更好的为油田开发服务。 In the early stage of the development of slim borehole, the lack of workover experience increased the difficulty and cost of well workover construction. According to the characteristics of the slim borehole, we analyzed and discussed the accidents such as the well litter falling in the slimhole well, Developed a set of mature technology for the recovery of small objects in the well drilling, better service for oilfield development.
