摘要
详细分析了荔湾3-1气田深水段管线路由区前期的勘察数据,并且结合路由区地形地貌特征、海底浅层土的分布与工程地质特性以及海底土体稳定性等要素对气田管线范围内土层进行了工程地质分区与评价,对在不稳定区的工程设施提出了相应的工程措施。荔湾3-1气田深水段管线路由区地质分区与评价有利于指导该区管线铺设与油气开采设备装配,同时也可为深水项目工程场地评价提供参考。
The engineering geological zoning and e- valuation are performed for the deep water segment of the proposed pipeline route in LW3-1 gasfield by a detailed analysis of the pre-survey data and combi- ning with the features of seafloor topography, shal- low soils distribution, engineering geological chara- teristies and seabed stability. Relevant engineering procedures are suggested for subsea infrastructures in unstable seabed area. This study has provided not only the guidance to the laying of subsea pipelines and the installing of oil N- gas production facilities in the area but also the reference to the evaluation of engineering site for deeDwater Droiects.
