- Abstract
The process of pile insertion and pile extraction for jack-up drilling platform is the key link in offshore construction of drilling platform. However, serious accidents may occur during operation of jack-up drilling platform such as pile leg puncture and platform tilt. In this paper, based on the calculation method of jack-up drilling platform pile driving, the penetration risk of jack-up drilling platform pile driving is analyzed comprehensively considering the factors of formation, pile shoe bearing capacity and pile group effect. According to the safety factor relative to puncture, the adaptability of drilling ship to insert pile at the predetermined well position is evaluated to realize the prediction of pile leg into mud in order to avoid the occurrence of complex accidents in the process of drilling and completion, guide the depth of pile leg into mud, improve the speed of offshore construction, reduce the risk of offshore operation and construction cost, and provide a scientific basis for offshore engineering design and construction..
