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 I turn on the electric bit?
- There are two kinds of commonly used, a card, a clip, clip to press the drill chuck can pull out the drill, clip with keys to open, can also be used when a round steel chisel, hammer knock loose counterclockwise on the line.
- Q: Do we need drill bit for cast steel drilling?
- The 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: M6 threads need to drill much bottom?
- A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
- Q: What measures can be taken to prevent the bit from breaking?
- In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit. Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.
- Q: What is the maximum available drill bit for an electric drill with a maximum diameter of 10mm?
- Of course, if it is not a cylindrical drill, but a hole opener, it can be as large as 100mm and open a round hole on a low density material such as a large board.
- Q: What drill is best?
- The drill bits are of high speed steel, of which 439365 are cobalt and cobalt is the best
- Q: How can the 1 millimeter drill be worn?
- Less grinding, orifice in three edge or pentagon, look carefully, really half a certain degree of difficulty, teachers see the grinding action, do not blindly grinding, students often have yet to settle on the edge by grinding the start on the wheel, too large angle drill in drilling look, all kinds of grinding defects of twist drill. The students have not mastered the sharpening skills and techniques, according to the methods and skills of practice summed up in simple formulas form explanation and demonstration, students tend to understand, the other main blade drill was destroyed, is less grinding in better control of miss the point, size, angle of the diagram. Look calmly. And after sharpening the edge of the blade.
- Q: I want to be in the stainless steel frame and fixed drill a few screws, with what bit and screw
- However, Hui Shang building materials network reminds you that when drilling, the speed should be lower, the back angle of the drill to be larger, and side grinding, grinding narrow, in order to reduce the side blade and hole wall friction. In addition, when drilling, it is best to add some vinegar to the drill bit, so it will be easier to drill holes.
- Q: How big are the 8 bits that have worked up?
- If 8mm's expansion pipe uses a drill with a diameter of 8mm, if it is a 8mm expansion screw, use a drill with a diameter of 12mm.
- Q: How do you drill a drill?
- 6, after grinding, the drill rotation, simulation, drilling, cutting the status of inspection, to see if there is no wrong place, if there is further grinding;7, grinding the cross edge, that is, symmetrical sharpening drill bit after the blade;The 8 big bits can be sharpened by grinding on the side of the grinding wheel;9, steel bad twist drill, the vertex angle can be properly worn. .
