New Technology of Coiled Tubing Drilling in Slim Hole

YUE Shuhai


Slim hole coiled tubing is a new drilling technology in the current decade. It combines slim hole technology and coiled tubing technology, which has a considerable number of advantages over conventional drilling methods in certain applications, such as reducing drilling cost and risk, increases drilling efficiency and is more environmentally friendly. Its applicability, technical characteristic, equipment, development and prospection at home and abroad are introduced in this paper.
Key words: Slim hole; Coiled tubing; Drilling technology; Technical characteristics; Drilling equipment
