Installation Method and Risk Control Technology of Surface Conductors

Deep-water surface conductor was the basis for the constructing deepwater wells,the risk of its installation was high,its operation was difficult.In addition,there existed differences between theoretical models and the actual situation,there was a risk of uncertainty.Once the operation was failure,it would induce a vicious or catastrophic accident.Based on the research of latest drilling information,the installation method of surface conductors and the design of key technical parameters are introduced.A risk identification analysis is carried out by using the jetting in deepwater drilling.The corresponding control measures are Put forward,and it provides an important guidance for deepwater drilling.
