滩海油气管道敷设方法

Pipe Laying Technique for Offshore Oil and Gas Pipelines

介绍了滩海区域油气管道的施工方式,即牵引法、铺管船法和定向钻法,分析了这三种施工方法的分类、特点和施工步骤。指出滩海管道施工方法,应根据不同工程的具体情况,综合考虑滩海的海况和地质状况,以及各种施工方式的效率、经济性和安全性等,选择一种或几种较合适的敷设方法。

This paper introduces a construction technique for offshore oil and gas pipelines, or pipe towing method, laying barge method and horizontal directional drilling method. Classification, features and operating steps of the 3 methods are analyzed. It is pointed out that based on different construction ways for offshore pipelines, one or more pipe laying methods should be used as more effective operating methods,and the efficiency,economy and safety of pipe laying techniques must be fully taken into account in allusion to different sea states and offshore geological conditions.
