摘要
建立了管柱接触非线性问题的间隙元法。用此方法对试油测试射孔管柱的受力状态进行了分析 ,并通过现场应用实例证明了此方法的可靠性和准确性。根据此方法开发的应用软件可为井下管柱的结构设计提供理论依据。
In this paper,the contact problem of tube string anal yz ed by the finite clearance element method is established. The force state of per foration tube string for testing of oil is analyzed with the finite clearance e lement method, and the field applied examples prove its reliability and veracit y. The application software, which is developed with the finite clearance elemen t method, can be provided as theoretical basis for the structural design of down hole tube string.
