基于全过程切割的海上油田井筒管柱切削力计算模型
Calculation model for cutting force of wellbore pipe string in offshore oil fields based on the entire process cutting
摘要
Abstract
Currently,hydraulic mechanical cutters are used for cutting production tubing,sand control tubing,and casing in offshore oilfield major repair wells and adjustment wells during sidetracking operations.It is one of the main technologies for wellbore preparation before such operations.The cutting force generated during the cutting process affects the lifespan of the cutter blades and the overall success of the operation.Existing methods for calculating cutting force simplify the comprehensive engagement of the cutting edge,leading to lower accuracy in cutting force calculations.To reveal the dynamic patterns of cutting force during cutting process,based on the principles of metal cutting and the actual cutting process,the cutting edge of the blade is divided into a circular edge that participates in cutting through rotational motion and a radial edge that engages in cutting as the blade continuously expands during the process.By applying milling geometry and kinematics,a cutting force calculation model is established,analyzing the entire cutting process of the circular and radial edges from a microscopic perspective to determine the cutting force magnitude.The impact of various cutting parameters on cutting force is also examined.The results indicate that hydraulic mechanical cutting involves variable cutting forces influenced by multiple factors.During a single cutting,the cutting force fluctuates,with the peak force exerted by the circular edge substantially exceeding that of the radial edge,and these peaks occur at different times.The research findings further reveal the dynamic patterns of cutting forces and the cutting process of hydraulic mechanical cutters.These insights are instrumental in guiding the selection of cutting parameters during on-site operations.关键词
