摘要
遇油\遇水自膨胀封隔器是一种新型的完井工具。利用自膨胀封隔器代替常规封隔器进行水平井完井,可以提高完井效率,降低完井风险,减少完井费用。介绍了自膨胀封隔器在水平井裸眼分段、固井辅助密封、多分支井完井3个方面的应用,并说明了该完井技术的工艺特点和技术优势。经多次现场试验,遇油\遇水自膨胀封隔器完井技术是成功的,对我国复杂油气藏的有效开采具有重要意义。
Oil/water-swelling packer is a new well completion tool in the oil fields. Compared to traditional packers,it makes horizontal completion simpler,reduce completion risk and cost. The paper focuses on application of oil/water-swelling packer to horizontal well completion:open hole zonal isolation, supplementary seal for cement and multilateral well completion. It describes to the completion process and technological advantages too. The successful applications show that the oil /water-swelling packers have a good performance. It is very important for complex hydrocarbon reservoir development to develop the completion technique in the future in China.
