Horizontal well top end steam injection device
The utility model provides a horizontal well top end steam injection device, and relates to a device used for oilfield production. The horizontal well top end steam injection device is provided with an outer tube provided with a steam outlet, a cone-shaped guide head is arranged at the front end of the outer tube, an inner tube is arranged inside the outer tube, a joint is arranged at the outer end of the inner tube, and a support plate is arranged between the outer tube and the inner tube. The horizontal well top end steam injection device can send steam to a far-well zone, and effectively reduces thickened oil viscosity; and good heating can be obtained by a near-well zone and the far-well zone, and exploitation of thickened oil is benefited.
