三相固体浮力材料的制备与应用研究

摘要

隔水管系统是海洋石油钻采的重要技术装备,而浮力材料是深水条件下钻井隔水管系统的必备部件.针对以深海石油钻采为重大应用背景的特种固体浮力材料,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,采用真空浇注工艺研发了一系列密度和强度的三相固体浮力材料,其密度为0.29～0.52 g/cm3,压缩强度为8.27～32.35 MPa,耐静水压为10～45 MPa,吸水率＜3％.同时结合海洋石油981平台南海钻采作业要求,系统开展了深海石油钻采隔水管浮力块的设计与制备研究,形成了隔水管浮力材料的国产化产品.%Drilling riser system is a critical component of marine oil drilling,and buoyancy material is an essential for deep-sea drilling riser system.In this paper,three phase epoxy solid buoyancy materials filled with carbon fiber reinforced hollow macrospheres and hollow glass microspheres was prepared by vacuum pour molding.The density of the composite is 0.29-0.52 g/cm3 and the compressive strength is 8.27-32.35 MPa.The water absorption of the composite is less than 3％ and hydrostatic pressure resistance is 10-45 MPa.The industrial production of huge reliable solid buoyancy module for 981 semi-submersibleoil platformis also designed and accomplished.The buoyancy module for deep-sea drilling is comprehensively designed,fabricated and characterized.
