nserted three-cone bit, 9.5 inches (241.3mm)

Product Description

Product Introduction of 9.*-inch (**1.3mm) Inserted Three-Cone Bit

 

In the exploitation of petroleum, natural gas and other resources, drilling operations are a key link, and the 9.*-inch (**1.3mm) inserted three-cone bit is an indispensable tool in drilling operations. With its unique design and excellent performance, it provides a strong guarantee for efficient drilling.

 

1. Product Overview

 

The 9.*-inch (**1.3mm) inserted three-cone bit has a diameter that precisely meets the needs of various drilling scenarios. Its main structure consists of three cones, cones' claws, bearings, water eyes, and an oil storage seal compensation system. Each cone is inlaid with high-strength and high-toughness cemented carbide teeth, which are the key components for the bit to achieve efficient rock breaking.

 

2. Working Principle

 

During drilling operations, the entire bit rotates clockwise around the bit axis, which is called revolution; while the three cones rotate counterclockwise around their own axes, which is called rotation. Under the dual action of drilling pressure and drill string rotation, the cemented carbide teeth on the cones crush and bite into the rock. At the same time, due to the overhang, compound cone and axis offset structure of the cones, the teeth slide on the bottom of the well, thereby realizing the shear crushing of the rock. When the cones roll on the bottom of the well, they alternately contact the bottom with single teeth and double teeth, causing the bit to produce longitudinal vibration. This vibration is converted into impact force on the formation, which, together with the static indentation force generated by the drilling pressure, realizes efficient crushing of the formation rock and enables the smooth extension of the wellbore.

 

3. Product Advantages

 

1. Excellent Cutting Performance: The inserted three-cone bit adopts high-strength and high-toughness cemented carbide teeth. The optimized design of the number of tooth rows, number of teeth, tooth exposure height and unique alloy tooth shape endow it with excellent wear resistance and cutting ability. It can show good rock-breaking effect whether in soft or hard formations, effectively improving the drilling speed.

2. Reliable Bearing System: A floating bearing structure is adopted. The floating elements are made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and their surfaces are treated with solid lubricants. This not only reduces the relative linear speed of the bearing pair but also reduces the temperature rise of the friction surface, greatly improving the bearing life and reliability under high drilling pressure or high rotating speed drilling process conditions, ensuring the stable operation of the bit under complex working conditions.

3. Good Sealing Performance: High-precision metal sealing is used, with a carefully designed and processed metal sealing ring as the axial dynamic seal of the bearing. Two high-elastic rubber energy supply rings are respectively located in the sealing areas of the cone palm and the cone as static seals. By optimizing the seal compression, it is ensured that the sealing surfaces of the two metal rings always maintain good contact, effectively preventing impurities such as drilling fluid from entering and protecting the bearing system and lubrication system.

4. Excellent Lubrication Guarantee: It is equipped with a full rubber oil storage bladder that can limit the pressure difference and prevent drilling fluid from entering the lubrication system, providing stable and good lubrication guarantee for the bearing system. At the same time, a new type of lubricating grease that can resist high temperature up to **0°C and is wear-resistant is used, adapting to harsh drilling environments such as high temperature and high pressure, and prolonging the service life of the bit.

5. Wide Application Range: It is suitable for various fields such as oil drilling and production, water well drilling, coal mine exploration, geological drilling, geothermal well development, and engineering pile foundations. For different formation conditions, the best drilling performance can be exerted by reasonably selecting the tooth shape and bit structure.

 

4. Application Cases

 

In an oil exploitation project, facing the complex formation structure, the 9.*-inch (**1.3mm) inserted three-cone bit was used for drilling operations. In the soft formation part, relying on its sharp cutting teeth and reasonable structural design, the bit achieved rapid drilling, and the mechanical drilling speed was increased by [X]% compared with the past; after entering the medium-hard formation, the cemented carbide teeth and solid structure of the bit withstood the test, stably completed the drilling task, and the wear degree of the bit was within an acceptable range, ensuring the smooth progress of the entire exploitation project, greatly shortening the construction period and reducing the exploitation cost.

 

If you need a reliable, efficient and practical bit in drilling operations, the 9.*-inch (**1.3mm) inserted three-cone bit will be your ideal choice.
