摘要
深水油气田资源区地质环境与工程地质条件复杂,潜在及可能诱发的地质灾害类型多且危害严重,工程勘察的技术含量高、施工难度大、周期长、费用高。科学规划工程勘察阶段和各阶段任务,对实施具体深水油气田工程勘察有事半功倍的作用。通过分析深水油气田资源区的地质环境和工程地质条件的复杂性,以及勘察内容与技术手段的适用性等,阐述深水油气田工程勘察科学规划和分阶段实施的必要性,以及参照相关领域工程勘察的阶段划分,提出深水油气田开发工程勘察的阶段划分概念,给出了分阶段实施方案和流程。
Deep-water oil and gas field resource areas have complex geological environments and engineering geological conditions,which will result in serious geological disasters,prolong engineering survey time and increase its costs. Thus,scientific and reasonable planning plays a positive role for implementing specific deep-water oil and gas field geotechnical investigation and survey. Analyzed are geological and engineering environment complexity of deep-water oil and gas resource areas and applicability of investigation content and technical means and expounded is the necessity of scientific planning and phased implementation on deepwater oil and gas geotechnical investigation and survey. By referring phase division of relevant engineering areas,proposed are phase division concept of deepwater oil and gas filed geotechnical investigation and survey and suggested are the phased implementation plans and procedures.
