摘要
随着我国经济的飞速发展,石油工业在国民经济发展过程中占据地位越来越重要,钻井质量会直接影响石油的出油效率,一口满足要求的好井,为后续石油开采奠定了良好的基础,大大提高石油出油效率,降低后续石油开采工作的困难程度和采油成本。陀螺减震工具作为新型钻井用提速工具,目前没有文献阐明陀螺参数对减震效果的影响。利用动态仿真软件对钻具进行动力学分析,之后构建陀螺减震效果试验装置来实际验证陀螺参数对减震效果的影响。将理论分析、动态仿真模拟分析、现场实验三者相互结合,验证当陀螺减震工具受到脉冲力矩时可以有效的降低震动振幅,将高频大幅度的震动降低为低频率小幅度的震动,减小外力对钻井效果的影响,随着陀螺转速的增加,陀螺减震工具达到稳定的时间越快。实验结果提供了陀螺仪应用于陀螺减震钻具的可行性及可靠性,这对目前石油钻井领域存在的技术难题具有重要的现实指导意义。
With the rapid development of economy in China,the petroleum industry plays an increasingly important role in the development of national economy.Drilling quality will directly affect the oil extraction efficiency of oil.A good well meeting the requirements lays a good foundation for subsequent oil exploration,greatly improves the oil extraction efficiency,and reduces the difficulty and cost of subsequent oil extraction.As a new speed-up tool for drilling,there is no literature to clarify the influence of gyroscopic parameters on the damping effect.The dynamic simulation software is used to analyze the drilling tool,and a gyroscope damping effect test device is built to verify the influence of gyroscope parameters on the damping effect.Combine theoretical analysis,dynamic simulation analysis and field experiment to verify that the vibration amplitude can be effectively reduced when the vibration damper of gyroscope is subjected to pulse moment,reduce the high-frequency and large-amplitude vibration to lowfrequency and small-amplitude vibration,and reduce the influence of external force on drilling effect.With the increase of gyroscope speed,the stabilization time of the vibration damper of gyroscope will be faster.The experimental results provide the feasibility and reliability of the gyroscope used in the gyroscope vibration-reducing drilling tool,which has important practical guiding significance to the technical problems existing in the field of oil drilling at present.
