| Abstract: | Oilwater-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 oilwater-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 oilwater-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. |
