The  PDC drill bits  are the abbreviation for the polycrystalline diamond composite bit. It is a drilling tool commonly used in the geological drilling industry. In fact, its evolution has evolved from diamonds. Applicable industry classification 1. The composite drill bit for geological exploration The composite sheet drill, which is mainly used for geological exploration and exploration, is suitable for soft to medium hard rock formations. Now some new composite sheets developed by some manufacturers can be applied to rock layers with ten hardness. 2.  Coal Cutting Drill Bits  using the composite drill bit It is mainly used for coal seam drilling and mining in coal mines. Generally speaking, the rock formation of the coalfield is relatively soft, and the composite drill bit is widely used, such as a bolt drill bit and a three-wing drill bit. 3. The composite drill bit for petroleum exploration Mainly used in oil and gas fields, drills are used. At present, the composit

Drilling work is a work that needs to be carried out with care. Some mistakes may cause the efficiency of the whole construction to drop and the quality is not guaranteed. Therefore, there are many preparations to be done before, and there is no need to be troublesome. Many accidents are caused by inadequate attention to small details. Today, I will introduce you to some things that we have to check before entering the well. The first is different drill bits with different geological requirements. such as  PDC drill bits , DTH bits, It is necessary to check the type and diameter of the drill bit. For the drill itself, it is necessary to check whether the drill is welded and the teeth are intact, as well as the firmness of the nozzle, the smoothness of the water eye, and the bearing. Special attention is paid to the inspection of these aspects of sealing, as this is the previous preparation work. Also, the drilling speed should be slower, so as to avoid hard formation damage to the

The  roller cone bit  has good structural characteristics in use. The following is a brief introduction to the structural characteristics of the cone bit. 1. The cone bit adopts floating bearing structure. The floating element is made of a new material with high strength, high elasticity, high-temperature resistance and high wear resistance. The surface is treated with a solid lubricant. By reducing the relative linear velocity of bearing pair and the temperature rise of friction surface, the bearing life and bearing reliability can be effectively improved under the conditions of high drilling pressure or high rotational speed drilling technology. 2. High strength and toughness cemented carbide teeth are used in the insert bit. The optimized number of teeth, the number of teeth, the height of exposed teeth and the unique shape of alloy teeth are used to give full play to the high wear resistance and the excellent cutting ability of the insert bit. A new wear-resistant material is

DTH drilling tools  storage during downtime is a neglected problem. The preservation of equipment and drill tools is very important for the use of equipment and drilling tools. The preservation of the drill pipe 1. Blowing the air, clean the water inside the drill pipe, and open the solder tail lubrication device. In principle, it is best to see the tail lubricant at the bottom of the drill pipe. 2. The outside of the drill pipe, including the threaded portion, and the main body of the drill pipe, must be wiped clean. At the same time, the male and female joint parts should be covered with the rubber cover to prevent the entry of pollutants. The rubber cover is small and cheap, which can greatly reduce the impactor failure caused by pollution. Short-term preservation of impactors 1. Blowing air to remove moisture from the impactor.  2. Fill 1 liter of tail oil from the upper joint. 3. Opening the air and blow for about 10 seconds. This will fully lubricate the internal p

Let's learn about the storage of  DTH drilling tools  impactors. Short-term storage First, blow away the water in the impactor. Second, add one liter of tail oil from the upper part. Third, open the wind and blow for about 10 seconds, so that the internal parts of the impactor can be fully lubricated. Fourth, It is like the drill pipe, the upper and lower joints are respectively covered with rubber covers. Fifth, placing the impactor horizontally in a dry environment. Long-term preservation First, blowing away the water in the impactor. Second, unscrewing the upper and lower connectors and disassemble the impactor. Third, checking and wipe all internal parts, preferably in clean rooms. Fourth, lubricating all parts properly with the suitable lubricant. Fifth, assembling the impactor and cover the upper and lower joints with rubber cover. Sixth, placing the impactor horizontally in a dry environment. We are  DTH drilling tools wholesaler , welcome to con

The end faces convex type: This kind of drill is divided into two forms, single convex platform and double convex platform, the latter is mainly used for larger diameter DTH bit. The end convex  DTH drill bits  can keep high drilling rate while drilling medium hard and hard abrasive rock, but the drilling flatness is poor, so it is not suitable for drilling engineering with high requirement of blast hole flatness. The End faces flat type: This shape of the drill bit is more durable, it is suitable for drilling hard and extremely hard rock, but also suitable for drilling medium and hard rock and soft rock with low flatness. The concave surface type: This shape has a conical concave part on the end face of the bit. It is a bit of nucleation during the rock drilling process to maintain the alignment performance of the drill bit. The drill hole has a good straight line. This drill bit has good drainage effect and fast drilling speed. It is a DTH drill bit that is used more on the mark

Let's take a look at the features of  roller cone bit . 1. The use of high-strength and high-toughness alloy teeth makes it improve the resistance of the teeth to impact, reduce the chance of broken teeth, and the soft formation is equipped with a spoon-shaped tooth. 2. A layer of the hard alloy is placed on the bearing of the tooth, and the roller bearing is also silver plated so that the bearing has improved the ability to resist seizure and load. 3. The O-ring seal adopts a more wear-resistant high-saturated nitrile rubber, which increases the cross-section of the seal ring, and increases the sealing small boss at the outer end of the seal area to improve the reliability of the seal. 4. the use of steel ball locking cone, can be suitable for relatively high speed. 5. The number of teeth to be optimized and the equipment such as the tooth and the alloy tooth can maximize the cutting and speed of the drill. 6. the use of a new production of grease that can withstand t

Hydraulic hammer drilling has turned out to be an innovative drilling technique to deal with hard and complicated rock formations through numerous developments and practices. A variety of hydraulic  DTH hammer  has shaped a new type of hole-bottom machine and will be more in-depth and greater degree of development. First of all, together with the evolution of high technologies and digital technologies, the theoretical research level of impact rotary drilling will have a fantastic breakthrough, the expressions of their mechanical components of the hammer and the moving portions of the hydraulic hammer with different structure types will likely be improved and enriched, and the structure and parameter layout of the hydraulic hammer will likely be further simplified, optimized and scientific by computer simulation. The evaluation way of the operating parameters of the hydraulic hammer will probably be more precise, intuitive and intelligent, and the new innovative technical detector
