摘要
微球聚焦测井仪推靠系统是广泛应用于石油测井领域内一种十分重要的辅助测井设备。随着新时代背景下油田的测井作业要求,对测井推靠系统机构自身的运动及动力性能提出了更严格的要求。为准确掌握微球极板在测井作业过程中的贴壁情况,保证微球聚焦测井的顺利,高效进行。现从推靠系统机构自身运动平稳性,机构初始传动角,极板推靠力等方面出发,应用闭环矢量链法建立了推靠系统的运动及动力学数学模型与物理仿真模型,通过数值计算仿真与虚拟样机仿真,对微球聚焦测井仪推靠系统的运动及动力性能进行研究,揭示推靠系统的运动及动力规律,校验所建立模型的正确性,并为推靠系统结构设计及结构参数优化提供依据。
As an important logging instrument widely used in the oil logging field, with the requirements of logging operation in oilfields in the new era, the pushing system of microsphere focusing logging tool has more stringent requirements are put forward for the movement and dynamic characteristics. In order to accurately master the adherence of microsphere plates in logging operation and ensure the smooth and efficient operation of microsphere focused logging. In this paper, an mathematical model and physical simulation model of the motion and dynamics are established by using the closed-loop vector chain method from the aspects of the motion stability of the pushing mechanism, the initial transmission angle of the mechanism and the pushing force of the polar plate. Through numerical simulation and virtual prototype simulation, the motion and dynamic characteristics of push system of microsphere focused logging tool are studied, revealed the motion and dynamic law of push system, verified the correctness of the model, and the basis is provided for the structural design and structural parameter optimization of push system.
