The problem of oil recovery, multiple groups cable bundle passes through.
To achieve the above object, the present invention uses following scheme:
Deepwater wells parallel double tube packer, comprising: top connection drives that there are two holes in the top connection, respectively with it is hydraulic
Washing pipe, the connection of auxiliary pipe screw thread；Wherein, further include packing element, set on packing element there are two tubing string hole, two tubing string holes respectively correspond and are inserted in
Hydraulic washing pipe and auxiliary pipe.
Compared with prior art, the invention has the following beneficial effects:
1, using packing element structure is improved, tubing string internal diameter is maximized, multiple groups cable bundle is able to achieve while passing through, increase simultaneously
Circulation area, to improve the oil production in the unit time.
2, compact-sized using double card tile structure, it can satisfy the complete well needs of deep water long well section, realize that multilayer is two-tube and adopt
Oil, and unsealing conveniently, directly on put on connector deblocking can be realized.
