摘　　要：针对油田开发前期钻井设计中对自升式平台就位考虑不足,导致平台场址位置、槽口布局、管线电缆走向等设置不够合理的问题,从而造成了重复就位、井口覆盖不全、插桩滑移、抛锚风险等就位难题。通过地质灾害条件识别技术、单桩PCPT承载力预测技术、自升式平台覆盖优选和避让技术、自升式平台抛锚优化设计等一系列就位设计优化技术,实现了平台场址优选、插桩安全、覆盖最大化及管缆合理走向,指导油田高质量开发。优化结果表明,就位设计优化内容贯穿油田开发设计的全过程,为海上油田安全高效开发提供设计依据和技术指导。In the early stage of oilfield development drilling design,insufficient consideration was given to the positioning of self-elevating rigs,resulting in unreasonable settings of rig site location,slot layout,pipeline cable routing,etc.,resulting in problems such as repeated positioning,incomplete wellhead coverage,leg sliding,and anchor risk.Through a series of positioning design optimization technologies,such as geological hazard condition identification technology,single pile PCPT bearing capacity prediction technology,self-elevating platform coverage optimization and avoidance technology,self-elevating platform anchor optimization design,etc.,the platform site optimization,pile insertion safety,maximum coverage,and reasonable pipeline and cable routing had been achieved,guiding high-quality oilfield development.The optimization results indicated that the optimization content of position design runs through the entire process of oilfield development design,providing design basis and technical guidance for the safe and efficient development of offshore oilfields.
