Specific implementation mode
The slips expanding deep water packer includes top connection 1, friction commutator segment 2, central tube 3 and slips 4；Central tube 3
Threaded one end is equipped with lower contact 5, and 3 other end screw thread of central tube is equipped with top connection 1；Top connection 1 and lower contact 5 and central tube 3
Between be sealed by O-ring seal.
Slip spider 6 is slidably fitted on central tube 3 between top connection 1 and lower contact 5, slip spider 6 is bullet, slips
The tapering outer surface of seat 6 is provided with pilot hole, and pilot hole is interior to be equipped with supporting rod 8 by support spring 7；On 6 circumference of slip spider
It is evenly equipped with multiple righting balls 15；It is in middle position always to protect the just slips expanding deep water packer at work.
Packing element A10 and packing element B11, pressure ring 9 and slip spider 6 are equipped with by pressure ring 9 on the central tube 3 of 6 side of slip spider
Between fixed by holding screw 13, packing element spacer ring 14 is provided between packing element A10 and packing element B11.
The length of packing element A10 and packing element B11 differ, and the upper and lower end face chamfering of packing element A10 and packing element B11 use different angles
Degree；The position up and down of packing element A10 and packing element B11 is equipped with meshy steel wire skeleton；To can effectively avoid packing element at work
The problem of end face occurs shoulder and leads to poor sealing.
