| Abstract: | Taking use of old well for
orientational sidetracking to reconsent and reevaluate geological configuration can greatly
reduce drilling cost and accelerate exploration and development process. This paper introduced
drill assembly and technological process while suspended sidetracking in Quxie 7 well.Its'
drilling fluid technology and decompressional releasing stuck technique are also described.
Success in this well can not only get remarkable economic benefit but also accumulate
experience for futural old well sidetracking technique. |
