Introduction For Down-The-Hole Drilling Method

图片
A down-the-hole drill, usually called  DTH Drilling Rig , is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer. Considering that the DTH method was initially designed to drill large-diameter holes in surface-drilling software, its title originated in the fact that the percussion mechanism adopted down the bit to the gap. Programs were afterwards discovered for the DTH process underground, in which the management of drilling is usually upwards rather than downwards. DTH didn't need hefty down thrusts or large rotational levels and as such a mild, cheap machine may be utilized to execute the drilling procedure - the system might also be operated by a single individual, whereas other systems demanded two operatives. The advantages that  DTH Well Drilling Rigs  attracted to the sector were so tremendous - for...

What Are the Types of Drilling Rigs?

图片
With the continuous development of   drilling rig machine  production , the use conditions of drilling rigs are becoming more and more diverse, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling methods, drilling depth, borehole size and drilling tool size, drilling area conditions (such as electricity or fuel, transportation, meteorological conditions), etc. The  t ruck mounted drill rig  is the main machine  that completes the drilling construction. It drives the drilling tool and the drill bit to the deep part of the formation and completes the lifting and lowering of the drilling tool and casing, and the extraction of the core through the elevator (winch) on the drilling machine. , Auxiliary work such as replacement of drill bit. The main function of the pump is to deliver flushing fluid into the hole to clean the bottom of the hole, cool the drill bit and lubricate th...

What are the drilling construction steps?

What are the drilling construction steps Due to different factors such as drilling depth, soft and hard geology, pressure, well length and so on, the construction period varies from more than ten days to more than one year. The drilling process is also quite complex, and  Portable Water Well Drilling Rigs Manufacturer  will discuss only the more important ones. 1. Lower the pipe sleeve Casing design is an important part of drilling. Any well will often encounter several different geological, depth or emergency conditions, production and development needs in the process of drilling, so it needs several layers of casing to protect the hole, in order to successfully drilling the target drilling. A perforating well is one that is drilled to a certain depth or stratum and then drilled with a smaller bit. In the case of well 141, the first stage was drilled with 171/2" bit to 1,500 meters, and then with 133/8" surface casing, only 121/4" bit was used... And so on. 2...
