摘　　要：随着钻探工作向深部地层发展 ,高温高压深井越来越多。深井测试是继地震勘探、岩屑录井、取心和电测之后唯一能直接测得地层流体特性和地层参数的方法 ,也是提高勘探、开发经济效益的重要途径。根据高温高压深井测试求产工况下测试管柱内外流体流动的实际情况和管柱在井中的受力、变形状况 ,建立了测试管柱求产工况的三维力学分析模型 ,采用数值分析方法得到测试管柱载荷、内力及变形等参数沿管柱轴线的变化规律 ,为深井测试管柱的设计和施工参数的确定提供了理论依据。Along with the development of drilling works to deep reservoirs,more and more deep wells with high temperature and high pressure will be drilled.After seismic exploration,cuttings logging,coring and well logging,the deep well testing is the only method of directly understanding formation fluid character and measuring reservoir parameters and is also an important way of raising economic benefit of exploration and development.According to the actual conditions of fluid flow inside and outside the testing string under the operating mode of testing for production in the deep well with high temperature and high pressure and to the loading and deformation of the string in wellbore,a three dimensional mechanic analysis model of the string under the operating mode of testing for production is established in the paper.The change laws of the parameters,as testing string loading,internal force and deformation,along string axis are detected by use of numerical analysis technique,which provides a theoretical basis for determining the parameters of the design and operation of testing string in deep well.
