【Abstract】 Coild Turbing Drilling (CTD) has been known as a new method of directional drilling in recent years.It has been used and developed since 1990’s.CTD can drill horizontal well more efficiently than normal drillrigs.It also can drill hole with underbalance drlling technology saftly and with less drilling fluids than rotate drilling operation at same depth.At present,It hasn’t been applied widely in our oilfields.In this paper,the equipment, and the function of all units are introduced and the applications of CTD in the future is elaborated.更多还原
