Optimization Application of Self-elevating Rig Positioning Design in Oilfield Development Process
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 positio-ning design optimization technologies,such as geological hazard condition identification technology,single pile PCPT bearing ca-pacity prediction technology,self-elevating platform coverage optimization and avoidance technology,self-elevating platform an-chor 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 opti-mization content of position design runs through the entire process of oilfield development design,providing design basis and tech-nical guidance for the safe and efficient development of offshore oilfields.
