摘　　要：埕岛油田区部分采油平台到达了设计寿命期,需进行延长寿命评估。为了确定合理的延寿设计准则,针对CB20A平台建立有限元数值模型,采用适应于油田所在海洋环境参数——波高、流速、风速的皮尔逊Ⅲ型分布,应用美国石油协会API标准提出的3种确定设计条件的准则方法进行了考察。研究结果表明:传统单因素方法偏于保守,整体弯矩最大情形与之接近,而最可能情形和联合环境条件设计情形得到的环境重现期极值设计准则使得平台弯矩降低显著,具有更好的延寿效果和推广潜力。More production platforms of Chengdao Oilfield are reaching the designed life,needing lifeextension assessment.In order to determine the reasonable life extension criterion,the finite elementnumerical model is established for the CB20A platform,where Pearson III distribution adapted to offshoreenvironment parameters including wave height,flow velocity and wind speed is adopted,to carry outinvestigations on the3criteria proposed by API standards.The results show that,method of traditionalsingle factor is conservative,and the overall situation of maximum bending moment is close to it.Thedesign criteria for extreme value of environmental return period obtained from most likely situation andcombined environmental conditions design make the bending momentdecrease significantly,indicatingtheir better effect for life extension and promoting potential.
