摘要
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.
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.
