摘　　要：随着海上油田的进一步开发,海上钻井平台钻探任务不断加重,自升式平台需要在不同油田的井位进行就位作业,为了保障就位作业的顺利进行,需要进行自升式平台在该井位的入泥深度及稳定性分析。在自升式平台作业期间,可能会遭遇恶劣的海况,需要研究分析自升式平台在某井位作业时发生侧滑的可能性,并推算可承受的最大风速。通过建立某自升式平台沉垫入泥深度模型和侧滑移模型,根据QHD32-6平台场址工程地质调查,结合抗滑移软件计算得出该自升式沉垫平台裙板在该井场场址的入泥深度、稳定性和极限环境条件。With the further development of offshore oil field the task of offshore drilling plaOCorm is increasing. Jack-up platform needs to be in place of operation in different oil wells. In order to guarantee in place operation smoothly, it needs＇ to be analyzed the well depth into the mud and the stability of the jack-up plageorm. During the period of operation of the jack-up platform, # may encounter rough sea conditions, which requires study and analysis of the possibility of side slip of the jack-up platform occurring in some wells and requires the calculation of the maximum wind speed that can be withstood. Through the establishment of a jack-up platform mat into the mud depth model and side slip model, according to the site engineering geological survey of the QHD32-6 platform, combined with the software, it is calculated the depth of the anti-slip mat apron in the site into the mud, the stability and the utmost environment conditions of the jack-up platform.
