Three Roller Tricone Drill Bit 8 1/2 Inch for Hard Rock Drilling


Three Roller Tricone Drill Bit 8 1/2 inch for Hard Rock Drilling


Discriptions:


Tricone bit is an important tool for oil drilling, its performance will have a direct impact on drilling quality, drilling efficiency and drilling costs. Tri-cone bit design is based on practical experience, combined with trial and error method, repeated design and calculation, the design accuracy is low, long cycle, it is difficult to improve the design quality, and each calculation can only design a drill, low efficiency.

Precautions for use:

a. Do not touch the roller bit gear when connecting and unloading the bit.

b. to keep the mud clean to prevent blocking bit of water eye, which affects the drill bit.

c. drill speed control to prevent sudden resistance, so that the roller cone drill to play a better effect.

d. Keep both pumps in good condition.

e. keep the bottom of the well clean, from the drill, drill into the mud scraper or cover the wellhead with steel, often check the pliers and pinhole insurance sales tools to prevent wellhead falling objects.

f. pay attention to the drill to prevent slippery drilling, Dun drilling.

g. Encountered a bizarre drilling, drilling time to adjust the drilling parameters.

h. Drill bit drill to the end, the first cycle of about 10 minutes, with 1-2 tons into about 0.5 meters, slowly pressurized to 6-8 tons of drilling. Drill evenly to prevent sudden damage to the vent, drill pressure generally not more than 10 tons. When you encounter slow drilling, to analyze, if it is because of the mezzanine to be patient, do not blindly add drill pressure.


Tri-cone drill bit is one of the most widely used drilling bit, with wide adaptation to the ground, the high penetration rate of the characteristics of the machine. Tricone bit from the cutting structure, bearing structure, locking components, oil seal, nozzle devices, such as more than 20 kinds of components. Tricone bit classification


1. Bearing Type: Rolling and plain bearings

2. Sealing type: rubber seal and metal seal

3. According to the fixed teeth are divided into: Indentation (carbide teeth) Tricone bit and milling gear (steel teeth) Tricone bit


Working principle:

Tricone bit in the weight-pressure and drill string rotation under the action of teeth crushed and eat into the rock, while sliding to produce some shear and rock. When the roller cone in the bottom of the scroll, the teeth on the cone impact in turn, into the formation, this role can be part of the rock bottom crushing, while the role of the roller along with the shearing effect of cutting away the residual teeth between the other Part of the rock, so that the bottom of the rock completely broken, the well can be extended.


Product advantages:

Drill bits are the most widely used in oil drilling and geological drilling. Tricone bits have the effect of rocking, crushing and shearing the formation rock during rotation. Therefore, the roller cone bit can adapt to various soft, medium and hard formations. Especially after the emergence of jet-type roller bits and long-nozzle roller cone bits, the roller bit drilling speed is greatly increased, which is a major revolution in the development of roller cone bits. Tricone bit by tooth type can be divided into milling teeth (steel teeth) roller bit, insert the tooth (carbide roller gear set) roller bit; according to the number of roller can be divided into single cone, double cone , Tricone and multi-roller bit. The most widely used at home and abroad, the most common is the tricone bit.


Rock drill bits are an essential part of the oil, exploration and drilling industries, but roller cone bits are too expensive for some drilling industries, prompting some drilling industries to produce large secondary roller cone bits Interest, its low price and reliable quality (only 1/3 of its lifespan is used in oil drilling) reduce the cost of the drilling industry so that used roller bits have become an important part of some of the drilling industry.

For Example


FJ517G three roller bit


Product category: Drilling, exploration, petroleum, bit, drilling accessories

Product Name: 215.9mm Jianghan metal inlaid three roller cone bit

Product Type: FJ517G


Structural features:


1. Floating bearing structure, the floating element by the high strength, high elasticity, high temperature resistance, high wear resistance characteristics of new materials, the surface of the solid lubricant treatment. Reducing the relative linear velocity of the bearing pair reduces the temperature rise of the friction surface, which can effectively improve the bearing life and bearing reliability under high-pressure or high-speed drilling conditions.

2 using high-precision metal seal. Metal seal consists of a well-designed metal seal ring as the bearing axial dynamic seal, two high-elasticity rubber energizing ring are located in the tooth palm and cone sealing area as a static seal, the optimized seal compression to ensure that two A metal ring sealing surface always maintain good contact.

3. Ball locking cone, to adapt to high speed.

4. With a full rubber reservoir that limits differential pressure and prevents drilling fluid from entering the lubrication system, it provides a good lubrication guarantee for the bearing system.

5. Adopt new grease that is resistant to high temperature of 250 ° C and anti-wear.

6 inserts with high strength and toughness carbide teeth, the optimal design of the number of teeth rows, teeth, tooth height and unique alloy tooth profile, give full play to the high wear resistance and excellent cutting ability of the bit. Steel tooth bit tooth surface welding new wear-resistant materials, while maintaining the high penetration rate of steel bit drilling while improving the bit cutter life.


Rubber seal tricone bit


Product introduction: H series drill is O-shaped rubber sealed sliding bearing bit, which can withstand higher weight-on-bit at normal speed.

Product category: Drilling, exploration, petroleum, bit, drilling accessories


The main structural features:


1. The use of high strength and toughness carbide teeth, improve the impact resistance of teeth to reduce the broken tooth rate;

Optimized design of the number of teeth, the number of teeth, tooth height and unique alloy tooth profile, give full play to the bit cutting ability and cutting speed;

3. Using snap-lock locking cone, can withstand high-pressure drilling;

4 cone weld inlay reduction alloy, improve anti-bite bearing capacity;

5. The use of highly saturated nitrile rubber O-ring, the optimized seal compression increases the bearing seal reliability;

6. Adopting a full rubber oil storage bag that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system, providing good lubrication for the bearing system and ensuring the normal working of "O" ring seal and improving the working life of the drill bit;

7. With 250 ℃ high temperature, low wear and tear of the new grease to improve the drill seal lubrication system high temperature capability.
