摘　　要：随着我国海洋油气资源开发的不断深入,浅层气发育区、海底地层薄弱区、海底地形复杂区等影响自升式钻井船插桩就位的风险也逐渐暴露,甚至影响油田整体开发方案,自升式钻井船就位前的风险识别非常重要。为提前对钻井船就位风险判断,辅助油田安全开发,风险识别取得了一系列的技术突破,高分辨率二维/三维地震探测井场调查技术、CPT钻孔测试工程地质调查技术、海上声纳扫描精细海底地貌调查技术等应运而生,形成了一套针对自升式钻井平台安全就位的风险识别技术。在我国海洋油气田勘探开发过程中,极大避免了钻井船倾斜、倾覆等风险,取得了很好的效果。自升式钻井船就位前风险识别为类似区域钻井船安全就位提供了技术支持,积累了经验。With the deepening of China's offshore oil and gas development,the risks that affect the pile insertion of jack-up drilling ves⁃sels in shallow gas development areas,weak seabed strata,complex seabed terrain and other areas are gradually exposed,and even af⁃fect the overall development plan of the oilfield.The risk identification before the jack up drilling vessels are in place is very important.In order to judge the risk of drilling vessel positioning in advance and assist the safe development of oil field,a series of technical breakthroughs have been made in risk identification.High resolution 2D/3D seismic exploration well site survey technology,CPT bore⁃hole test engineering geological survey technology,offshore sonar scanning fine seabed landform survey technology and other technolo⁃gies have emerged,forming a set of risk identification technology for the safe positioning of jack up drilling platforms.In the process of exploration and development of offshore oil and gas fields in China,the risks of inclination and overturning of drilling ships have been greatly avoided,and good results have been achieved.The risk identification before the jack up drilling vessel is in place has provided technical support for the safe positioning of drilling vessels in similar areas and rich experience is accumulated.
