Abstract

A drag type of continuous layered fracturing bottom sealed packer has been developed to elevate fracturing efficiency. Adopt mechanical lift and lower the string to implement the sealed and unsealed; the sealing structure is simple, rubber sleeve is short and performance of seal is stable; the anchoring is solid, which is suitable for all kinds of grade of steel casing; set the balancing device in the interior of the packer to balance the upper and lower pressure of the glue tube after work is done; sand control device is specially designed on the packer to prevent sand sticking that may occur during operation. The multiple applications on the scene suggest that the performance of drag type of bottom sealed packer is excellent and partly replaces the similar imported products.
