Application of Chemical Cutting Technology in Complex Processing of Coiled Tubing
Taking the actual construction well X as an example,this paper analyzed in detail the causes of coiled tubing stuck and the difficulties of unstuck technology,and proposed the scheme of chemical cutting technique for unblocking.Based on the introduction of structure characteristics and working principle of the chemical cutter,the feasibility and effectiveness of the chemical cutting tech-nology were verified by the successful application in X well.The results show that the chemical cutting technology is simple and reli-able,has good cutting effect,good practicability and economy,and provides an important reference for the treatment of similar small diameter tubing stuck accident.
