Everyone knows that the role of Tapered Button Bits is mainly mechanical equipment for drilling water wells and completing operations such as downhole pipe and well washing. Including power equipment and drill bits, drill pipes, core pipes, drill stands, etc. Generally, it is divided into three categories: rotary rotary, impact drill and compound rotary. The following water well drilling rig manufacturers briefly introduce the use steps of water well drilling rigs for everyone
1. Lower sleeve
The sleeve design can be said to be the highlight of drilling. During the drilling process, any well often encounters several different geology, depth or emergencies, production and development requirements, etc. Therefore, several layers of casing are needed to protect the well hole in order to successfully drill into the target drilling.
A borehole is drilled from a borehole to a certain stratum depth or level, and then the next layer of casing is drilled with a smaller size drill bit. Take Well No. 141 as an example. In the first phase, after drilling down to 1,500 meters with a 171/2" bit, the 133/8" surface pipe sleeve is first dropped, and then only a 121/4" bit can be used for drilling... etc. .
2. Drilling out and drilling down
In order to replace a blunt bit, or prepare a core sample, repair equipment, or plan to do other work in the well, it is necessary to lift the drill and the bit to the ground, and then remove the blunt old bit and connect the new one. Select the new drill bit and follow the reverse order of the trip, and then go down to the bottom of the original well to start drilling.
The deeper the drilling, the more time it takes to trip and drill, but the actual drilling time is relatively reduced. Therefore, how to choose a good drill bit to increase the drilling progress, reduce the number of trips and shorten the construction period is also the responsibility of the engineer.
3. Mud and drilling
The biggest feature of Drilling Tools Manufacturer's rotary drilling method is the use of mud as the circulating fluid in the well.
