Side through electric immersed pump wellhead

The utility model relates to a side penetrating type electric submersible pump well mouth that a cable of the electric submersible pump penetrates from a shoulder of a tubing head. The utility model is characterized in that the cable of a tubing well mouth of the electric submersible pump penetrates from the shoulder of the tubing head; the utility model adopts a cable sealing packing to seal fluid in the well, and thereby, the utility model avoids that the cable is extruded when the well mouth of the electric submersible pump seals a tubing hanger at present to result in damage of a cable insulation layer at position of the tubing hanger. A christmas tree and the tubing hanger of the side penetrating type electric submersible pump well mouth is the same as a self-jetting well, and the utility model can be used in the self-jetting well; after the well is transformed into oil extraction by the electric submersible pump from self jetting, a casing tube gate is transformed into a flange (2), a packing box (3), a sealing packing (4), a sealing packing pad (5), and a packing box pressing cover (6); the utility model can be arranged on the shoulder of the tubing head (1) to convert into the side penetrating type electric submersible pump well mouth.
