浙江油田海安油区的大规模开发迫切需要建设工艺管道通过新通扬运河。通过分析新通扬运河的地质情况,地下水分布和地震效应,确定管道通过方案(即采取定向钻穿越新通扬运河)和穿越设计要点(穿越层位选择、入、出土点选择、钻具的选择等)。随后阐述了新通扬运河穿越施工的技术和措施。最后,对穿越设计和施工提了几点建议。
Large-scale development of the Hai’an Oilfield in Zhejiang Oilfield urgently requires the construction of process pipelines through the new Tongyang Canal. Through the analysis of the geological conditions, groundwater distribution and earthquake effects of the new Tongyang Canal, the project of pipeline pass (ie directional drilling through the new Tongyang Canal) and the crossing of design points (crossing the selection of strata, selection of entry and exit points, drilling tools Choice, etc.). Then elaborated the new tongyang canal through construction technology and measures. Finally, we made some suggestions on crossing the design and construction.
