Description

Cutting type reamer

Technical Field

The utility model relates to a enlarger technical field especially relates to a cutting formula enlarger.

Background

Reamers are classified into the following two types:

a hydraulic underreamer: the hydraulic reamer is a tool for expanding or resetting the blades of the reamer by using water pressure to enlarge the diameter of a drilled hole, or is used for partially enlarging the diameter of the drilled hole after the drilled hole is formed. The piston is downwards supported out of two fins arranged in the reamer body under the action of the pumping pressure of slurry, and the drilling tool drives the fins to rotate to scrape the hole wall and enlarge the hole diameter. After the pump pressure is relieved, the flap is retracted into the body under the action of the spring.

A diamond reamer: because the difference between the diameter of the diamond drill bit and the outer diameter of the core tube is very small, the gap between the hole wall and the core tube is reduced, the water passing is blocked, and the drill jamming is easy to cause. The diamond reamer is a short column-shaped pipe body, the upper and lower steel body portions are respectively connected with drill bit and core tube by screw threads, the middle portion is a superhard material matrix covered with diamond, its external diameter is slightly greater than the diameter of diamond drill bit (about 0.5 mm to 2 mm), and on the side surface of matrix a water-passing trough is set, so that the water flow can be passed through. In very hard and abrasive rock formations, it is also known to use two or more reamers, spaced apart from one on top of the drill bit, between the core barrel.

Because friction easily takes place between the drilling rod of current reamer and the last grade pore wall, draw the reaming back to the multistage work in addition for the drilling rod wearing and tearing are serious, change the drilling rod and also increased cycle and construction cost. To this end, a cutting reamer is proposed.
