在试油试采过程中,油井要进行试油测试射孔的施工作业,要借助由特定组合的管柱串将井下工具或有关的仪器送入到预定位置。然而作业管柱在井下的受力情况十分复杂,影响因素多,工作条件恶劣,因此,为保证井下作业施工的安全顺利进行,对井下作业管柱的受力变形分析和强度评定显得十分重要,它为管柱设计和安全施工提供可靠的理论依据。
In the test-oil production process, the well needs to carry out the oil test to test the perforation construction. The downhole tool or related instrument should be fed to the predetermined position by the string of strings with a specific combination. However, the stress of working pipe string in underground is very complicated, with many influencing factors and poor working conditions. Therefore, it is very important to analyze and evaluate the stress and deformation of downhole work pipe string in order to ensure the safe and smooth operation of downhole work. It provides a reliable theoretical basis for the pipe string design and safe construction.
