[Working Principle of Tricone Bit]
When the tricone bit rolls at the bottom of the well, the teeth The teeth on the wheel impact and press into the formation in sequence. This action can crush part of the rock at the bottom of the well. At the same time, the shearing effect caused by the sliding of the cone cuts away the other part of the rock remaining between the teeth, completely crushing the rock at the bottom of the well. The wellbore was extended. _Copy
[Three-cone drill bit types]
, sealing types rubber seal and metal seal.
, bearing types rolling bearings and sliding bearings.
According to the way the teeth are fixed, they are divided into three-cone drill bits with insert teeth and three-cone drill bits with milling teeth.
[Select the drill bit according to the structural properties of the stratum]
1. Rotary drilling bucket with single soil inlet for hard cement.
2. For mud, soil and pebble layers that are not very sticky, double-layer bottom augers are often used for digging.
3. Rotary drill bits with a single bottom layer of clay layer, weathered rock cone core drills and conical auger drills.
4. Combination of a conical auger for strongly weathered rocks, or a household double-bottomed auger. Various situations can be transformed depending on the situation.
5. For frozen soil layers, you can choose a combination of bucket-tooth auger and rotary drilling bucket. If the freezing degree is high, use a conical auger.
The tri-cone drill bit plays a major role. Its function can form shallow pile holes on the surface. Rocks are exposed to wind and sun in nature, and very complex geological crustal changes occur. Our country has diverse terrain and vast land, so the three-cone drill bits work on particularly complex objects.
