Abstract
A reducer pipe hoop capable of changing an outer line of a solid sucker rod into an inner line of a hollow sucker rod belongs to the technical field of sucker rod pipe hoops. The pipe clamp comprises a pipe clamp body, wherein a lower threaded hole and an upper threaded hole are axially formed in the pipe clamp body, the lower threaded hole and the upper threaded hole are mutually communicated, the aperture of the lower threaded hole is smaller than that of the upper threaded hole, a ring table is formed on the inner wall of the lower threaded hole, and a wire through hole is axially formed in the ring table. The utility model is used for the external wiring of the solid sucker rod, and directly heats the heater, but the lead cannot pass through the oil well sealing device (mainly seals the annular space between the oil casings to prevent the leakage of oil gas) and cannot be connected with the travelling cable. The utility model can lead out the lead through the hollow sucker rod, thereby solving the problem of connection between the lead and the travelling cable and not affecting wellhead packaging.

The utility model aims to solve the problems in the prior art and further provides a reducer pipe hoop with a line outside a solid sucker rod changed into a line inside a hollow sucker rod.
The utility model aims at realizing the following technical scheme:
The utility model provides a change pipe hoop that line was walked outside solid sucker rod becomes to walk line in hollow sucker rod, includes the pipe hoop body, the inside axial of pipe hoop body is opened has lower screw hole and last screw hole, lower screw hole and last screw hole intercommunication each other, and the aperture of lower screw hole is less than the aperture of last screw hole, and the inner wall of lower screw hole forms the ring platform, and the axial of opening on the ring platform has the wire through-hole.
One to twelve wire through holes are formed in the annular table of the pipe hoop body.
Nine wire through holes are formed in the annular table of the pipe hoop body.
The utility model has the beneficial effects that:
The utility model uses the external wiring of the solid sucker rod to directly heat the heater, but the lead cannot pass through the oil well sealing device (mainly sealing the annular space between the oil casings to prevent the leakage of oil gas) and cannot be connected with the travelling cable. The utility model can lead out the lead through the reducer pipe hoop, solves the problem of connection between the lead and the travelling cable, and does not affect wellhead packaging.
