| description | The utility model relates to a horizontal well leaking and channeling finding pipe column. The horizontal well leaking and channeling finding pipe column is composed of an oil pipe column, a centering guide, a packer, a sliding sleeve switch and a sieve pipe. The centering guide, the packer, the sliding sleeve switch and the sieve pipe are installed on the oil pipe column from top to bottom in sequence. The centering guide and the packer are directly connected together. The sliding sleeve switch is composed of an outer sleeve, a sliding sleeve, a shear pin and O-shaped rings. A pressure releasing hole is formed in the exterior of the outer sleeve, the sliding sleeve is of a solid cylinder structure, and sealing grooves are formed in the parts, near the upper end and the lower end, of the exterior of the sliding sleeve. The O-shaped sealing rings are installed in the sealing grooves, and therefore sealing between the sealing grooves and the outer sleeve is achieved. An annular groove is formed in the lower portion, and the sliding sleeve is fixed into the annular groove and the outer sleeve. The horizontal well leaking and channeling finding pipe column has the advantages that during setting, by means of the centering device and a slip, the horizontal well leaking and channeling finding pipe column can be positioned with the center of a sleeve, a rubber sleeve can conduct releasing evenly along the circumference, and long-term effective setting of a horizontal well section is ensured. |
