High speed screw drilling rig mud motor for oil drilling
Mud motor is a part of screw drilling tools, which is a volumetric downhole power drilling tool that uses drilling fluid (mud) as a power source to convert liquid pressure energy into mechanical energy. It uses an internal power conversion mechanism to generate power through the flow of mud, thereby driving the drill bit to rotate and achieve drilling operations.
working principle
The working principle of a mud motor can be simply summarized as follows: when the mud pumped out by the mud pump flows through the mud motor, a certain pressure difference is formed at the inlet and outlet of the motor, which drives the rotor inside the motor to rotate around the axis of the stator. The rotor and stator mesh with each other to form a spiral sealed cavity, and energy conversion is achieved through the lead difference between the two. The rotational force of the rotor is transmitted to the drill bit through the universal shaft and transmission shaft, causing the drill bit to rotate and break the rock.
component
The mud motor is mainly composed of stator, rotor, universal joint, bearing assembly and other parts. Among them, the stator is made by injecting rubber lining on the inner wall of the steel pipe, and its inner hole has a specific geometric parameter spiral shape; The rotor is a screw with a hard layer that meshes with the stator.
advantage
High efficiency: Mud motors have high conversion efficiency, which can fully convert the hydraulic pressure of mud into the rotational power of drill bits, improving drilling efficiency.
Strong adaptability: Mud motors are suitable for various formations and drilling conditions, and can maintain good drilling performance in both soft and hard formations.
Compact structure: The structure design of the mud motor is compact, making it easy to install and maintain. At the same time, its internal components have strong wear resistance and corrosion resistance, which can adapt to harsh drilling environments.
- Q: Which is better, a white drill or a black drill?
- Black becomes nitrided and can be used to drill aluminum products, i.e., soft materials, after improved propertiesThere are 3 processes for producing drills, black for rolling and worst for rolling. White for clean edges and ground. Because, unlike rolling, no high temperature oxidation, the steel grain structure is not damaged, used to drill a slightly higher hardness workpiece.The yellowish brown drill, called cobalt cobalt drill in the industry, is the unspoken rule of the drill. Cobalt containing drills were originally white, produced by grinding, and when they were atomized at the later stage, they were made of yellow brown (commonly called amber), which is the best in circulation. M35 (Co 5%)
- Q: How many diamond grinding wheels should be used for an alloy bit?
- If the hard alloy is generally 100 mesh coarse grinding, and then finishing 180, we have foreign customers dedicated to the electroplating grinding wheel are generally parallel to that, the two particle size. Plain drills and cutters use CBN wheels.
- Q: What's the difference between a drill bit and a drill bit?
- The material of the drill is differentAnd the head of the drill is not the same designThe drill used to drill wood will not drill in, or in the course of drilling, the hole will be burned, resulting in drillingThe drill used to drill iron will also fail to drill in, and the drill will be burned during drilling so that it can not be drilled
- Q: How do you determine the speed of the drill? Is there any standard?
- Large hole processing speed is not too fast, too fast, easy to make the head color (coke), resulting in turn annealing, eventually scrapped;Small rotor speed should be fast forward to the amount of slow, fast, easy to break, turn around, pay attention to crumbs.
- Q: Can an electric drill bit a wall?
- Hammer: single wall drilling tool. Compared with the percussive drill, it is much higher than the impact drill;
- Q: Can HSS drill bits be drilled into stainless steel?
- No, we should use alloy drill bit, drill vertex angle to 135 degrees, you can use the drill grinding machine repair grinding, our company is using Dongguan Muller machine drill grinding machine, grinding effect is good.
- Q: How big is the screw hole at the back of the torch chuck? Is it a rebound?
- Screw head, some cross flower, six angle, etc.. Generally, the thread is covered with a lock gum.If you want to remove it, it should turn clockwise.
- Q: What are the main points of drill grinding?
- Make sure that the edge of the blade is symmetrical to the axis and the sides are slowly repaired. When the edge is sharpened and the other side is sharpened, the edge must be in the middle of the axis of the drill bit, and the edges of both sides must be symmetrical. The symmetry of the experienced teacher will look to the light point, slowly grinding. Drill cutting edge angle is 10 DEG -14 DEG, after large angle, the cutting edge is too thin, when drilling vibration badly, orifice in three edge or pentagon, the chip is acicular; small angle, drilling large axial force, easy to cut, the cutting force increases, temperature rise drill, severe fever, or even drilling. For after the angle grinding, the tip of two edged, symmetrical, drilling bit, chip light, no vibration, no enlarged aperture.
- Q: Drill hammer type matching specifications
- Four, five, six pit pit angle shank hammer respectively with four pits, five pits, six angle shank drill.
- Q: Why not hammer drill iron
- Motor protection device: comprehensive in use will inevitably have hard granular access to a machine (especially on the machine to work on drilling, such as drilling on the top wall), if there is no certain motor protection, rotating at high speed can easily be hard break or scratch enameled wire, eventually lead to the motor failure.
