摘要:

针对顺北油田苛刻的腐蚀环境和特殊的地形地貌,地面集输管线建设面临沙丘起伏大(落差>10 m)、移动性强(沙暴天气>1个月)等不利因素,开展非金属材料管体和接头的受力分析和结构设计研究。利用有限元分析软件对不同内径的管材在不同外压载荷作用下展开的分析,计算管材在不同载荷下对管材挠度与应力的影响,校对所设计的结构是否能达到使用标准。结果表明,在内压载荷下增强层是主要承压层,增强层损坏意味着管道的失效;外压载荷下的风力载荷对管道影响最小,惯性载荷与沙丘移动均对悬空管道产生较大影响,可以通过应力分析来判断管道连接的可行性。

Abstract:

There is an urgent requirement for treating the harsh corrosive environment and special topography of the Shunbei Oilfield. The construction of ground gathering and transportation pipeline has to face a series of unfavorable factors such as the large dunes (drop > 10 m) and strong mobility (the period of sand storm > 1 month). A study on the force analysis and structural design of metal pipe bodies and joints was carried out in this work. A finite element analysis software was employed to analyze the pipes with different inner diameters under different external pressure loads. The effect of pipe materials on the deflection and stress of the pipes under different loads was calculated. The designed structures were compared to find an optimal result to meet the requirement of use. The results indicated that the reinforcement layer acted as a main pressure-bearing layer under an internal pressure load. The damage of reinforcement layer represented the failure of the pipeline. The wind load under an external pressure load exhibited little influence on the pipeline, and however the inertial load and sand dune movement generated a greater impact on the suspended pipeline. The feasibility of the pipeline connection can be judged by stress analysis.

Key words: desert environment, inertial load, wind load, sand dune movement, pipe connection
