针对现有简易膨胀试验装置存在的膨胀力小、膨胀速度慢、膨胀过程和现场实际不一致等问题,设计了专业的实体膨胀管实物膨胀评价装置。该装置可模拟油田现场井下膨胀情况,对膨胀管进行膨胀检测和评价,且可在单纯的机械拉力或单纯的水压或两者共同作用下对膨胀管进行膨胀试验。利用该装置还可进行钢管膨胀变形规律研究、膨胀管材料选择和开发、膨胀锥优化设计、膨胀工艺研究等,在保证膨胀管产品质量的同时将大力促进实体膨胀管的国产化。
In view of the existing problems such as the small expansion force, the slow expansion speed, the actual expansion process and the actual inconsistency existing in the existing simple expansion test equipment, a practical physical expansion expansion device for physical expansion pipe is designed. The device can simulate the field underground oilfield expansion, expansion of the expansion tube to detect and evaluate, and can be a simple mechanical pull or a simple water pressure or a combination of the expansion of the expansion tube test. The device can also be used to conduct research on the law of expansion and deformation of steel pipe, selection and development of expansion pipe materials, optimization design of expansion cone, and expansion process. While ensuring the quality of expansion pipe products, domestication of physical expansion pipe will be greatly promoted.
