| Abstract: | According
to the old well characteristics,the paper analyses the old well re-entry technology
(sidetracking and deeping)in  139.7 casing in Zhongyuan Oilfield.Through the redrilling
practices of more than ten old wells,the paper introduces directional sidetracking slim
hole technology in 139.7 casing,especially drilling design,oriented window
milling,trajectory control,bit uses,selection of drilling method,hole reaming,downhole
safety precaution and completion technique etc.some drilling technique features.Finally,it
analyses occuring questions and gives some suggestion. |
