Development Status and Trends of Jack-up Drilling Platform Pile Penetration and Uplift Technology
This paper systematically reviews the key technologies involved in the pile insertion and uplift for the geotechnical problems faced by jack-up drilling platforms.The geotechnical testing technology,soil failure mechanism,bearing capacity of upper hard and lower soft strata,and pile foot sliding issues met in the pile penetration process are analyzed.The research progress of calculation methods for pile pulling resistance and the methods for reducing pile pulling resistance during the pile uplift process are elaborated.On this basis,the focus of future research on the penetration and uplift technology of jack-up drilling platforms is proposed in accordance with the new challenges faced currently,and the developing trend is put forward.
