Three cone drill bit for oil drilling tools
The three cone drill bit is an important tool for oil drilling, and its performance will directly affect the quality, efficiency, and cost of drilling
Structure:
Drill body and palm: The upper part of the drill body has threads connected to the drilling tool, and the lower part has three palm parts connected to the roller shaft neck for support.
Roller cone: There are two types of structures: single cone and complex cone. Single cone is suitable for hard and highly abrasive formations, while complex cone is suitable for soft and medium hard formations.
Bearings: There are two types: rolling bearings and sliding bearings. Rolling bearings are equipped with roller bearings and ball bearings, while sliding bearings replace the roller bearings in rolling bearings with sliding sleeves.
Water hole: a channel for drilling fluid. A regular drill bit water hole is drilled at an appropriate position on the drill bit body and equipped with a water hole sleeve. A jet drill bit is equipped with a hard alloy nozzle at the water hole.
Oil storage seal compensation system: prevents drilling fluid from entering the bearing chamber, supplements lubricating grease to the bearing chamber to ensure lubrication of the bearing, and improves the service life of the drill bit bearing.
Working principle:
The three cone drill bit breaks rocks by rotating the cone and alternately contacting the cutting teeth at the bottom of the well, suitable for formations ranging from soft to hard.
Application scenarios:
Three cone drill bits are widely used in oil and gas exploration and extraction, suitable for various geological conditions.
Advantages and disadvantages:
Advantages: Suitable for a wide range of geological formations, high mechanical drilling speed, and relatively wear-resistant.
Disadvantages: Low design accuracy, long cycle, low efficiency.
- Q: How do the drills grind?
- A formula: "edge on the wheel surface." This is the first step between the bit and the grinding wheel, and it is often the students who have not cut the edges of the blade, so they start sharpening on the grinding wheel. It must be hard to wear. The blade here
- Q: How do the new pros and cons drill the drill bit without the key?
- This is the hand chuck chuck, is divided into two parts, the front end is used for elastic, rear end is fixed, you want to unload the drill, left to right back to the front to turn in the opposite direction can be loose, Anhui, Bozhou, great electrical firm opened, welcome patronage. Address is: Wanfu market, B building, No. 76-77, which is the general agent of broad brand. Cost-effective
- Q: What's the difference between full mill and rolling twist drill?
- A word is not clear, the different processing technology, the high production cost of drilling grinding, rolling and drilling cost is relatively low, also has the gap, drill grinding durability is more than fifty percent higher than in the rolling, and workpiece cutting performance, drill to drill a lot, I was the production
- Q: What's the difference between a UC drill and an ST bit?
- The ST drill is easy to operate, easy to control diameter, more grinding times, and its range of use is relatively large. It can be used in general use, which is beneficial to general diameter drilling and double face plate and more than 6 layers of panels.
- Q: What are the tools, drills, and any of the machine tools made of?
- (1) tungsten cobalt carbide, whose code name is YG, consists of CO and wc. Commonly used brand machine tools, bending strong, not afraid of impact, but hardness and heat resistanceIts characteristics are: good toughness, high bending strength, not afraid of impact, but low hardness and heat resistance. Applicable to the processing of cast iron, bronze and other brittle materialsThe commonly used grades are YG3, YG6, YG8 and so on. The latter figures indicate the percentage of cobalt content. The higher the cobalt content, the better the performance of the impact resistance. Therefore, YG8 is often used in rough machining, and YG6 and YG3 are often used in semi finishing and finishing.(2) tungsten titanium carbide, whose code name is YT, consists of WC (tungsten carbide), Tic (Tan Huatai) and CO (cobalt). Commonly used grades are YTl5, YT30 and so on. Its characteristics are: hardness of 89 ~ 93HRA, heat-resistant temperature of 800~1000 degrees; wear resistance and oxidation resistance are higher; but flexural strength and impact toughness are lower. Suitable for processing carbon steel, alloy steel and other plastic materials.Join titanium carbide can increase the wear resistance of the alloy, alloy and plastic materials can improve the bonding temperature, reduce tool wear, can also increase the hardness; but more brittle, poor toughness, performance under impact is also poor, generally used for processing plastic materials. Common brands are YT5, YT15, YT30, digital is behind the percentage content of titanium carbide, titanium carbide content is higher, the red rigid; but the corresponding cobalt content is lower, the worse the more toughness, impact resistance, so YT5 is commonly used in rough machining, YT15 and YT30 are commonly used in semi finishing and finishing processing.
- Q: 14 what big expansion wire does the drill use?
- Different expansion bolts form different drill diameters, and the maximum outer diameter of the bolt can be measured.
- Q: What are the main points of drill grinding?
- The edge of the drill must swing up and down, and the tail of the drill can not stand up. This is a standard bit grinding action. The main cutting edge swings up and down on the grinding wheel, that is, the hand holding the front of the drill must swing the drill bit up and down evenly on the grinding wheel surface. The handle of the hand can not swing, but also to prevent the rear handle to go up, that is, the tail of the drill can not be high above the horizontal center line of the grinding wheel, otherwise it will make the edge of the grinding blunt, unable to cut. This is the most crucial step, the drill is worn well and bad, there is a lot to do with it. At about the same time, start at the edge of the blade and rub it gently in the back, so that the back of the blade is more polished.
- Q: What brand of drill iron?
- A drill for drilling ironThe drill material is usually made of high speed tool steel or carbide, and high speed steel is often used in the factory. When drilling, it will be added coolant according to the different materials and rotating speed.
- Q: How do the front and back angles of the drill change? How does it affect drilling?
- The front angle of the drill is the angle of the spiral groove of the drill. It is generally unchanged. After the drill angle should change according to the situation of the processing hole; for example, when drilling, the drill bit at the outer edge of the general angle generally between 8~14 degrees, if you want to draw it by fossa, orifice chamfering drill, drill angle will be smaller, the cutting edge of the drill will be down, like this helps maintain a steady state of the drill bit, rowed out nest and chamfer to smooth, does not produce the phenomenon of polygon.
- Q: An expansion screw with a diameter of 20. How much impact bit do you need to use?
- The table above is the reference value of the match;2, the specific adaptation, also need to be flexible according to the actual situation, if the fixed place expansion screw is loose, need to be reduced if the fixed impact drill specifications; expansion screws tight place, according to the above table match.
