摘　　要：以南海北部湾某边际油田开发为例,从地基承载力、在位运动响应、钢材用量等3个关键角度,对2种基础型式的可移动采储平台进行对比分析。研究结果表明:沉垫基础对地基表面平整度要求较高,桩靴基础场地适应性更强;当场地存在薄软泥表层时,沉垫基础须增设裙板抗滑;桩靴基础需要对是否会发生穿刺破坏进行评估;沉垫基础平台在位运动性能优于桩靴基础平台;桩靴基础平台用钢量小于沉垫基础平台。在可移动采储平台基础选型设计中,应综合考虑具体油田参数和环境地质条件等因素。Taken the development of a marginal oilfield in Beibu Gulf of the south China sea as an example, contrastive study on two foundation types of the production and storage platform is carried out from the perspectives of foundation bearing capacity, in-place motion response and steel consumption.The results show that: mat foundation is of higher requirement of soil surface smoothness;spud-can foundation is more adaptive to site;when the site has thin soft clay surface, skirt board must be added to mat foundation to prevent sliding;it is necessary to evaluate the possibility of puncture failure for spud-can foundation;in-place motion performance of mat foundation platform is better than that of spud-can foundation platform;the steel consumption of spud-can foundation platform is less than that of mat foundation platform. In the foundation selection design of mobile production and storage platform, oilfield parameters and environmental geological conditions should be considered comprehensively.
