The upper part of the well section generally has loose rock cementation and softness

During the drilling process, we will often encounter bad drilling situations. The drill bit is about 1 meter from the bottom of the well. After drilling, when the drill bit is a single root from the bottom of the well, the pump should be opened to wash the well. When drilling, we should make full use of cutting and pay attention to chip removal; control and use according to the corresponding standard methods , Can show important characteristics and value in different professional fields.

 

Nozzle circlip (the circlip can be flexibly rotated after being inserted into the groove to indicate that it has been locked properly, otherwise it should be re-inserted); the roller bit spins the nozzle into the water hole of the bit before the bit enters the well, carefully analyze the use of the previous bit and In the downhole situation, prepare for the good use of the bit. When loading and unloading him, they are all fasteners that need to be used to avoid direct contact with various metal objects,custom Ship Auger Bit Manufacturers his cutting teeth, and then check the water eye of the drill bit. To load and unload PDC drill bits, use a special upper and lower buckle tool. If there is a phenomenon of skipping drilling downhole, the drill bit should be checked out in time.   

 

The use condition of the tri-cone bit is very important, and it is a prerequisite for a better job. When we are working on this bit, especially when connecting During the unloading process, we should not touch the drill bit to the bit gear in it. In a state of multi-directional compressive stress, the pores of the rock are reduced and the strength is increased. If a drill accident occurs, report it truthfully so that correct handling measures can be taken, and an accident report should be written in accordance with relevant regulations and requirements. Record the use parameters of the drill in detail.

 

When there is a pause or when it is relatively slow, you need to stop and perform related analysis, and then perform related operations. Only in this way can a good drill bit be ensured. The upper part of the well section generally has loose rock cementation and softness. If it is invalid, the drilling will be decisively tripped and changed according to the eye-drawing procedure.

 

It is widely used in drilling, and it can be said to be a not very good choice. At this time, we must adjust the relevant parameters in time to solve the problem. The downhole conditions are normal, the borehole is unobstructed, and the drill bit can go down to the bottom of the well smoothly; the drill bit should be lightly pressed and slowly rotated to touch the bottom of the well.  The bottom of the well is clean and there is no metal falling objects.Tri-cone drill bit, it is a kind of drilling partner, and it has been used for many years. 

It is strictly prohibited to knock the cones and threads

When working in soft rock formations and changing the drill bit in the middle, it is necessary to strictly check whether the alloy teeth on the palm back of the old drill bit and the roller cone fall off custom Ship Auger Bit Manufacturers to the bottom of the hole. After the teeth are crushed and eaten into the rock, they also slip and shear the rock at the same time.

During normal piercing operations, the main air path of the air compressor should not have serious air leakage to ensure sufficient air volume and air pressure to extend the service life of the drill bit. When it is rolling at the bottom of the well, the teeth on it will sequentially impact and press into the formation. The drill bit should be reasonably stored on the drill to prevent dust and other debris from entering the drill bit.

When drilling rigs, follow the principle of matching the three elements of drilling (wind pressure, axial pressure, and speed) with the parameters recommended by the drill bit sample. When the drill bit is in the hole and the air compressor suddenly stops working, the slag can easily enter the drill bit. When the drilling tool is in the hole, it is strictly forbidden to reverse to prevent the drill bit from falling into the well. When the drilling rig is stopped, the drilling tool cannot be parked in the hole with water to prevent slag and water from flowing back into the bearing and damaging the drill bit.

When there are cracks in the rock or rock cracks caused by blasting and the work in the mined-out area, the axial pressure and speed should be reduced to prevent the teeth from breaking. In the process of transportation, it is strictly prohibited to knock the cones and threads.

The remaining rocks in between broke the rocks at the bottom of the well and the well bore was extended. It is strictly forbidden to use curved drill pipes to avoid uneven force on the three palms of the drill bit and accelerate the damage of the drill bit. After the teeth are crushed and eaten into the rock, they also slip and shear the rock at the same time
