目前我国的油田管道施工技术仍停留在原始的手工操作阶段,如人工挖沟,手工焊接,人工回填,人工装卸等。油田建设中的这个薄弱环节或多或少地影响了石油工业的总体发展。本文就管道施工的几道主要工序介绍了国外管道施工的先进方法与设备,具体涉及施工前的选线,管子的运输与存放,挖沟,焊接,管子下沟,回填等,并对比了国内外的施工水平,概括地总结了国外管道施工技术的特点。
At present, China’s oilfield pipeline construction technology still remain in the original stage of manual operation, such as artificial trenching, manual welding, artificial backfill, manual handling and so on. This weakness in oilfield construction has more or less affected the overall development of the oil industry. In this paper, we introduce the advanced methods and equipment of pipeline construction in foreign countries, including the route selection before construction, transportation and storage of pipe, trenching, welding, ditch under pipe, backfill, Outside the construction level, summarizes the characteristics of foreign pipeline construction technology.
