针对在测井过程中测量仪器易损坏以及测量不精准的现象,结合声波测井法,并且根据收缩膨胀式原理设计一种带有减振、防撞机构的测井仪器,它由地上设备和地下设备两部分构成。从设计原理着手,对其结构组成模块进行详细论述,再通过三维建模软件,建立其三维虚拟样机结构模型,最后运用有限元分析方法,对主要的易损构建进行静力学分析,以此对该结构做进一步优化设计。通过实践及分析结果表明:该装置结构简洁、便于携带并且节约成本,自动化程度高,测量更加准确,使用寿命长,符合简洁型和经济型的现代化设计理念,为今后实际油气井的开采工程将提供一定的参考价值。

In view of the phenomenon that the measuring instrument is easy to be damaged and the measurement is inaccurate in the logging process,combined with the acoustic logging method and according to the contraction expansion principle,a logging instrument with vibration damping and anti-collision mechanism was designed,which was composed of aboveground equipment and underground equipment.Starting from the design principle,the structure composition module was discussed in detail,then the three-dimensional virtual prototype structure model was established through three-dimensional modeling software,and finally the finite element analysis method was used to carry out static analysis on the main vulnerable construction,so as to further optimize the design of the structure.The practice and analysis results show that the designed device has the advantages of simple structure,easy to carry,cost saving,high degree of automation,more accurate measurement and long service life.It conforms to the modern design concept of simplicity and economy,and provides a certain reference value for the actual oil and gas well production project in the future.
