通过对大井眼井 (套管规范为Φ139 7mm)和小井眼井 (套管规范为Φ10 1 6mm和Φ114 3mm)落物在井内遇卡、解卡和打捞特点的分析 ,给出了在小井眼井中对遇卡事故的处理方法 ,即 :对于砂卡、盐水和矿物的结晶卡、胶件卡、封隔器卡、小件落物卡等主要采用震击方法 ;对于水泥凝固、化学物质凝固、电缆、钢丝绳类落物堆积卡主要采取钻铣磨解卡方法。提出了一套适合小井眼井解卡打捞的配套工艺和自行研制的打捞工具 ,并给出了现场应用的效果分析
By analyzing the characteristics of encountering cards, jamming and retrieving in the wells of large wellbore (casing specification Φ139 7mm) and slimhole (casing specifications Φ10 1 6mm and Φ114 3mm) Wells in the wells on the handling of the accident, that is: sand cards, salt and mineral crystal cards, plastic cards, packer cards, small pieces of falling cards mainly shock method; for cement coagulation, chemical coagulation , Cables, Rope-like litter accumulation card to take the main drilling and milling solution card method. Put forward a set of matching technology for the well drilling well solution and self-developed fishing tools, and gives the effect analysis of the field application
