![]() ![]() In particular, the bit used in high-grade and horizontal wells requires a reasonable gauge structure. It is gradually realized that the gauge structure also has a great influence on the bit penetration rate and life span of the bit. For a long time, the improvement of the cutting structure mainly focused on the main cutting tooth structure, for example, in the cemented carbide tooth structure, people have invented wedge teeth, spoon-shaped teeth, partial top spoon-shaped teeth, such as wear gear and so on. It is confirmed that the improvement of the drilling rate has a greater impact on reducing the drilling cost than the improvement of the drill bit life, in which the improvement of the drill cutting structure is to improve the drilling machine The most direct method of drilling speed. Increasing the penetration rate and service life of the drill bit is an effective way to reduce the drilling cost. Life expectancy and penetration rate of two performance indicators, they ultimately determine the extent of drilling costs impact drilling. ![]() Significant improvements in bit performance directly reduce drilling costs, especially in the recent decade. ![]() According to the cutting material can be divided into steel teeth (milling teeth) and indented roller cone bit.Īs a tool for drilling rock formations, roller cone bits have been widely used. Tricone bit can adapt to a variety of formations from soft to hard.Īccording to the number of roller cone can be divided into single cone bit, three roller cone bits and assembly of multi-cone bit. The total working length is relatively large, thereby reducing the wear. When the roller bit is working, the cutting teeth alternately contact the bottom of the well, the breaking torque is small, and the contact area between the cutting tooth and the bottom of the hole is small, which is higher than the pressure and easy to eat into the formation. Tricone bit is the most widely used type of drilling bit. The end result? Fewer trips, less downtime, and superior efficiency.API Thread Tricone Roller Drill Bits Used In Oil Drilling And Geological Drilling It’s based on a powerful combination of advanced rock modeling and validation in our fully equipped test rig. Our artificial intelligence-powered, web-based application can build a digital-twin model that identifies the perfect bit to meet specific drilling challenges. With decades of experience in bit design and manufacture, we know drill bits and how they perform in any given situation. Leveraging advanced data-driven modeling and powerful computer simulations, our decision-making process is rooted in extensive domain expertise. Our Bit Selector tool rapidly assesses all three to identify the perfect bit from our comprehensive product range-whatever your field-specific drilling challenge. To reduce non-productive time and manage costs, it’s vital to match your bit to three factors: the formation, your operating envelope, and the bottom-hole assembly. Poor drill-bit selection results in disappointing rate of penetration, sub-par build-rate, and too many trips.
