复合材料水下防护结构在海洋油气开发的应用

Application of composite materials protector in the subsea of offshore oil

随着海洋油气开发的快速发展,水下生产设施越来越多,与此同时,海洋渔业捕捞方式及捕捞设备发展迅速,渔业活动对这些水下设施的影响也越发明显,被拖网、落锚损伤和破坏事故时有发生。为了保证海上油气安全生产,需对水下设施进行保护。纤维增强复合材料具有重量轻、强度高、耐腐蚀、不易生长海生物等特点,在制作海洋油气开发水下设施防护结构方面应用前景广阔。本文主要对此类复合材料防护结构的应用情况进行概述,并与钢结构、水泥压块防护结构进行对比分析。

With the rapid development of offshore oil and gas development,there are more and more underwater production facilities.At the same time,marine fishery fishing methods and fishing equipment are developing rapidly.The impact of fishing activities on these underwater facilities is becoming more and more obvious,and they are damaged by trawling and anchoring.And destruction accidents happen from time to time.In order to ensure the safe production of offshore oil and gas,underwater facilities need to be protected.Fiber-reinforced composite materials have the advantages of light weight,high strength,corrosion resistance,and difficulty in growing marine organisms.Therefore,the application of protective structures for marine oil and gas development underwater facilities has broad application prospects.This article mainly summarizes the application of this type of composite material protection structure,and compares and analyzes it with steel structure and cement briquette protection structure.
