摘　　要：以电缆式地层测试器接头螺纹为研究对象,利用ABAQUS软件建立了地层测试器接头螺纹有限元模型,分析了不同工况、不同尺寸的接头螺纹等效应力分布规律,并进行了室内试验验证。数值仿真和试验结果表明,接头螺纹的承载性能能够满足实际需求。Taking formation tester EFDT joint thread as a study example and using ABAQUS soft- ware,the finite element model of formation tester EFDT joint thread was established. The equiva- lent stress distribution under several different working conditions and different sizes were ob- tained with the help of ABAQUS software. And indoor tests of EFDT joint thread were also con- ducted. The research results showed that the bearing properties of joint thread can satisfy the practical requirements.
