| 中文摘要:可膨胀波纹管技术是通过对圆形管材进行特殊工艺处理，使管径发生变形以便其顺利通过井孔到达问题地层，然后通过液压膨胀复原，达到修井固井的目的。经过多年的技术发展，此技术已在石油工程中得到很多实践应用，但是在口径相对较小的地质勘探孔中，由于受口径以及工艺技术等限制，尚未有相关应用。主要针对材料编号为KP02的φ75 mm小口径梅花状可膨胀波纹管进行研究，通过利用ANSYS有限元软件进行模拟以及实验室实验，得到其膨胀变形参数并对其膨胀过程进行对比分析。 |

| Abstract:Expandable convoluted tube technology is based on a special process on round tubing to make the tubing deformed so as to it can smoothly reach the trouble formation through the borehole; then by hydraulic expansion recovery, workover and cementing are realized. This technology has been used in petroleum engineering a lot after its many years’ development, but due to the confinement of the diameter and technology, it has not been applied in geological prospecting with smaller diameter. This paper presents the study that is mainly based on φ75mm small diameter quincuncial shape expandable convoluted tube being made of KP02 seamless steel tube, expansive transformation parameters are obtained by simulation with ANSYS finite element software and indoor experiments, and the contrast and analysis are made on the expanding process. |
