Drill bits for oil rigs

Rotary drilling bits are usually classified as drag bits or rolling cutter bits according to their design. All drag bits consist of fixed cutter blades that are integral to the body of the bit and rotate as a unit with the drill string. This type of drilling bits dates back to the introduction of the rotary drilling process in the 19th century.. . Dull bit grading is a standard method to grade the bit, and it will also help personnel to understand bit performance better. However, it is sometimes very difficult to understand the. . The drill-off test for any oilfield drilling bits determines the optimum weight on bit and overall bit performance. A given amount of weight is put on the bit, and the draw works brakeis. . The penetration rate that can be achieved by a bit has an inverse effect on the drilling cost per foot. The main factors that affect the penetration rate are 1. bit type 2. formation properties 3. drilling fluid properties 4. bit weight and rotary speed 5. bit hydraulics [pdf]

Rotary bits drill the formation using primarily two principles: 1. Rock removal by exceeding its shear strength and 2. Removal by exceeding the compressive strength. The broken rock is removed by rotary scraping or hydraulic cleaning. Either process can also contribute to the initial breakage. Most drilling. . Diamonds embedded in a matrix have been used since the early Chinese dynasties; however, modern usage for mineral exploration. [pdf]
