井下钻具耦合振动测量模型及实钻数据分析
Coupling Vibration Model and Real Drilling Data Analysis of Bottom-hole Assembly
摘要
Abstract
In order to monitor the actual vibration of the downhole drill string,adjust drilling parameters to control the vibration charac-teristics of the downhole drill string,optimize drilling,and improve drilling speed,an analytical dynamic model of drill string vibration was established.In order to interpret and characterize different vibration forms of drilling string by measuring acceleration signals,the characteristics of sensor output signals under specific vibration modes were studied,and the relationships between sensor output signals and drill string vibration modes were analyzed.By studying the acceleration signal characteristics corresponding to vibration modes in simulated signals,the vibration information of the drill string is obtained from the analysis of actual drilling data,providing a basis for the quantitative analysis and motion mode interpretation of downhole drill string vibration signals.关键词
