摘要

海洋附着生物对海洋油气生产结构物影响很大,主要危害是增大平台桩腿的体积和表面粗糙度,腐蚀海洋石油平台结构,影响潜水员的水下作业等。通过对位于渤海湾冀东油田人工岛登陆点的700多根海洋钢桩的外观检测,给出了海洋钢桩的海生物附着情况,分析了海生物生长机理及规律,论述了海生物附着对海洋油气生产的危害,介绍了采用涂装防污涂料、电解防污、超声波防污及机械防污等技术抑制和清除海洋钢桩海生物的方法,最后根据油田的现实情况提出了相应的应对措施。
        The main hazards of marine organism attachment to offshore oil and gas production structures include increasing platform pile volume and surface roughness,corroding platform structure,affecting diver operation,and so on. Based on the appearance inspection of more than 700 marine steel piles in the artificial island landing structure in Jidong Oilfield in Bohai Bay, this paper presents the situation of marine organism attachment to those steel piles, analyzes the growth mechanism of marine organism attachment and its hazard to marine oil and gas production, introduces the antifouling methods to inhibit and clean the marine organism attachment, such as using antifouling paint, electrolysis, ultrasonic waves and mechanical means. Finally,according to the actual situation of the oilfield,the corresponding countermeasures are put forward.
