Abstract
The utility model discloses an electric submersible pump oil production well head device, an electric submersible pump cable of which gets through an adapter flange of a mandrel hanger (3) and a Christmas tree (2) as a whole. The electric submersible pump cable gets through the adapter flange of the mandrel hanger (3) and the Christmas tree (2) as a whole and is sealed with a whole packing set at an outlet of the cable, and the complex structure is changed that the prior electric submersible pump cable on well head separately gets through from three holes on the adapter flange of the mandrel hanger and the Christmas tree and every cable is sealed with separate cable sealing packing set. The Christmas tree and the mandrel hanger of the electric submersible pump oil production well head device is the same as that of a flowing well, if the cable outlet of the adapter flange of the mandrel hanger (3) and the Christmas tree (2) is blanked off with a bull plug, the Christmas tree and the mandrel hanger can be used for the flowing well, moreover, the pressure-proof grade of the Christmas tree and the mandrel hanger conforms to that of the body of electric submersible pump well head device.
Description
The utility model relates to the wellhead assembly of electric submersible pumping well, the whole electric submersible pumping well wellhead assembly that passes that is a kind of electric submersible pump cable from the adapter flange of tubing hanger (3) and production tree (2).
At present, in the electric submersible pumping well, the electric submersible pump cable passes from tubing hanger, production tree adapter flange, and three cables pass separately from three holes, and every cable adopts independent cable seal packing to come the sealed well inner fluid, complex structure, and the engineering time is long.
The purpose of this utility model provides a kind of novel electric submersible pumping well wellhead assembly, to avoid the above-mentioned shortcoming of present electric submersible pump well head device.
The cable of this electric submersible pumping well wellhead assembly integral body from the adapter flange of tubing hanger (3) and production tree (2) passes, adopt whole cable seal packing to come the sealed well inner fluid, form by tubing head (1), production tree (2), tubing hanger (3) and sealed packing pad (4), integral sealing packing (5) and packing box gland (6), it is characterized in that electric submersible pump cable integral body from the adapter flange of tubing hanger (3) and production tree (2) passes integral sealing.
Tubing head (1) is installed on the casing head, and is consistent with conventional tubing head structure, and production tree (2) sits and to be placed on the tubing head (1), and electric submersible pump cable integral body from the adapter flange of tubing hanger (3) and production tree (2) passes; Provide sealing by sealed packing pad (4), integral sealing packing (5) and packing box gland (6), packing box gland (6) adopts bolt to be connected with the adapter flange of tubing hanger (3) and production tree (2), the extruding force that fastening bolt produces makes integral sealing packing (5) distortion, gap between the adapter flange of sealing electric submersible pump cable and tubing hanger (3) and production tree (2), thus reach the purpose of sealed well inner fluid.
Fig. 1 is the general structure schematic diagram of electric submersible pumping well wellhead assembly;
Fig. 2 is the adapter flange structural representation of production tree (2);
Fig. 3 is the structural representation of tubing hanger (3);
Fig. 4 is the structure chart of sealed packing pad (4).
Fig. 5 is the structure chart of integral sealing packing (5);
Fig. 6 is the structure chart of packing box gland (6);
Below in conjunction with Figure of description installation of the present utility model is described further.
Tubing head (1) is installed on the casing head, operation is lowered to the electric submersible pump unit routinely, the electric submersible pump unit is down after the degree of depth of design, connect 1 oil pipe more, connect tubing hanger again, cut off the electric submersible pump cable at the following 1m of tubing hanger place, cable is bundled on the oil pipe, the tubing hanger seat is placed in the tubing head (1) with strain relief clamp.
After tearing blowout preventer open, on carry tubing string, cut off strain relief clamp, unload 1 unnecessary oil pipe, connect tubing hanger, near the cable the tubing hanger is gone measure such as armour skin handle, whole cable is passed tubing hanger, tubing hanger sat be placed in the tubing head (1).
Installation tubing hanger sealing: sealed packing pad (4), integral sealing packing (5) and packing box gland (6) are installed, are finished of the sealing of electric submersible pump cable at the tubing hanger place.
Whole cable is passed the adapter flange of production tree (2), production tree is installed.
The adapter flange sealing of production tree (2) is installed: sealed packing pad (4), integral sealing packing (5) and packing box gland (6) are installed, are finished of the sealing of electric submersible pump cable at the adapter flange place of production tree (2).
The advantage of electric submersible pumping wellhead assembly is that cable integral body from the adapter flange of tubing hanger (3) and production tree (2) passes, and adopts whole cable seal packing to come the sealed well inner fluid, have simple in structure, the characteristics of easy construction.
Claims (3)
1, a kind of wellhead assembly that is used for the electric submersible pumping well, form by tubing head (1), production tree (2), tubing hanger (3) and sealed packing pad (4), integral sealing packing (5) and packing box gland (6), it is characterized in that the electric submersible pump cable passes from the adapter flange of tubing hanger (3) and production tree (2), adopts whole packing_seal at the cable outlet place.
2, electric submersible pumping well wellhead assembly according to claim 1, it is characterized in that the electric submersible pump cable adopts whole packing_seal at the adapter flange place of tubing hanger (3) and production tree (2), come extrusion integral sealed packing (5) by the extruding force of packing box gland (6), the gap between the adapter flange of sealing electric submersible pump cable and tubing hanger (3) and production tree (2).
3, electric submersible pumping well wellhead assembly according to claim 1, it is characterized in that cable outlet is with after extremely blocking on the adapter flange of tubing hanger (3) and production tree (2), can use in flowing well, its voltage withstand class is consistent with the body voltage withstand class of electric submersible pumping well wellhead assembly.
