摘　　要：隔水管系统是海洋石油钻采的重要技术装备,而浮力块是深水条件下钻井隔水管系统的必备部件。笔者使用碳纤维增强聚合物中空球,与环氧树脂、空心玻璃微珠以适当比例混合,采用真空浇注工艺制备3组分隔水管浮力材料,并采用有限元软件ANSYS对浮力块在不同的工况下进行强度分析。研究结果表明,浮力材料密度为500kg/m^3,压缩强度为60 MPa;浮力块最大变形发生在其自由端,其值为4.08mm;最大应力发生在与隔水管相邻的结构上,其值为50.02MPa。最大变形值和应力值均很小,所制备的隔水管浮力块强度满足3 000m水深以内钻采作业要求。Drilling riser system is a critical component of marine oil drilling,and buoyancy module is essential for deep-sea drilling riser system.In this paper,three phase epoxy buoyancy materials filled with carbon fiber reinforced hollow macrospheres and hollow glass microspheres was prepared by vacuum pour molding.Strength analysis has been conducted on the buoyancy modules with different load conditions by using ANSYS.The results show that the density of buoyancy material is 500 kg/m^3 and the compressive strength is 60 MPa.The maximum deformation of buoyancy modules occurs in the free end with a value of 4.08 mm.The maximum stress occurs on the structure adjacent to riser with a value of 50.02 MPa,which makes the prepared buoyancy modules meet the drilling requirements of 3 000 m water depth.
