This paper mainly introduces the structural composition,operating principle,major technical parameters,design features and technical features of the amphibious modulized skid-mounted coiled tubing unit(CTU).It also describes the experimental condition of this unit and its application in Jidong Oilfield.The unit has been successfully operated in Jidong Oilfield 30 well-times.The maximum lifting or snubbing depth is 2,300 m;the velocity is 15 m/min;the manifold pressure is 20 MPa;the maximum deviation angle is 35.8°.It has successfully realized the modularization of the CTU.The whole system uses an explosion-proof design,which achieves the second class of explosion-proof grade in the oilfield operation area,and gets the explosion-proof certificate and certification of the China Classification Society.It also obtains the marine operation qualification.This paper has a certain referential significance for the CTU’s design and research.
