- W2373744144 abstract "At present, the maturing fields in the Henan east have entered a high water - cut stage. The main problems consisting in water plugging are that oil intervals alternated with water intervals in a zone. When continuous perforating in this zone, the oil and water intervals can't be separated. The existing packers can't meet the demands of water plugging in the inter - zone and thin interbeds. In order to solve these problems, a packer for plugging perforation was developed. This packer mainly consists of setting part, sealing part, and releasing part. It has the features of opening by fixed pressure, assisting release by elasticity, good sealing property and longer sealing period. This packer has been used in 10 wells with technical success ratio of 97% and efficient rate of 86. 6 % ." @default.
