基于ANSYS的随钻声波测井隔声体强度分析

Numerical Analysis the Isolator's Strength of Acoustic Logging while Drilling Based on ANSYS

利用ANSYS对周期性非轴对称凹槽结构随钻声波测井隔声体上最大等效应力进行了数值计算。建立了凹槽参数与最大等效应力之间关系。数值计算结果表明:凹槽深度、过渡弧半径以及凹槽圆心角大小对随钻声波测井隔声体上最大等效应力影响较大。相关研究结果对设计随钻声波测井隔声体有重要参考价值。

The maximum equivalent stress on sound insulator with non-axisymmetry groove structure of acoustic logging while drilling was calculated using ANSYS,also the relationship between the maximum equivalent stress and the groove parameters were established.Numerical results show that the maximum equivalent stress on sound isolator of acoustic logging while drilling were influenced bigger by the transition arc radius、groove depth and central angle of groove,all these research results are very important for designing the sound isolator of acoustic logging while drilling.
