随着海上边际油田开采年限的增加和产能的递减,越来越多的采油平台进入到弃置阶段。由于生产设施拆除工程复杂、危险,不确定性因素较多,因此它是一项涉及诸多技术领域的系统工程。某边际油田是渤海湾首个整体拆除弃置项目,在管理、技术上无经验可循,故而该项目的实施,对保护海洋环境的可持续发展具有重要的现实意义。 With the increase of the exploitation margin and the decrease of production capacity of offshore marginal oil fields, more and more oil production platforms have entered the disposal phase. As the dismantling of production facilities is complicated, dangerous and has many uncertainties, it is a systematic project involving many technical fields. Some of the marginal oilfields are the first overall dismantling and disposal project in the Bohai Bay and have no management or technical follow-up. Therefore, the implementation of this project is of great realistic significance for the sustainable development of the marine environment.
