Problems solved by technology

[0002] The sliding reamer is designed to drill holes during the sliding operation. At present, the common reamer used in the market has a small torque during the reaming process. The pulling force on the device is relatively large and it is easy to cause the drill to be stuck, and the function of the ordinary reamer can only meet the requirements of reaming, and the usage is single, not flexible and convenient

Abstract

The invention discloses a sliding hole winging machine, and relates to the technical field of design and manufacture of a hole winging machine used in an oil field. The sliding hole winging machine comprises a drill column body, and a hole swinging section is arranged on the drill column body; the peripheral face of the hole swinging section is provided with a first spiral band, a second spiral band and a third spiral band; wheel body installation grooves are formed in working faces of the first spiral band, the second spiral band and the third spiral band respectively; tooth wheel components are arranged in the wheel body installation grooves in a detachable mode respectively. A cylinder body of the sliding hole winging machine can be changed rapidly, by replacing with hard tooth wheels, the sliding hole winging machine can serve as a sliding centralizer used for centralizing a drill column and underground drilling tool components, meanwhile the sliding hole winging machine can rotate uniquely, drilling is prevented from being clamped, the hole swinging efficiency is improved, the use is convenient, and the flexibility and multiple purposes are achieved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of reamers used in oil fields. Background technique [0002] The sliding reamer is designed to drill holes during the sliding operation. At present, the common reamer used in the market has a small torque during the reaming process. The pulling force on the reamer is relatively large and it is easy to cause drill sticking, and the function of ordinary reamers can only satisfy reaming, and the usage is single, not flexible and convenient. Contents of the invention [0003] The object of the present invention is to provide a sliding reamer which can avoid drill sticking, improve reaming efficiency, and is convenient, flexible and multi-purpose. [0004] The present invention includes a drill string body, on which a reaming section is arranged, and the reaming section is a cylindrical structure with an enlarged diameter; on the outer peripheral surface of the reaming section, a firs...
