The variety of drilling machines and drilling equipments



Drilling machine is really a kind of equipment which is utilized to drill within the earth surface. It consists of some large-scale Engineering Drilling Rigs that are utilized to drill water well, oil well, and nature gas well. In the same time, additionally, it includes some small size equipments which may be moved by a single person, and they are known as twist drill or hand drilling machines. Drilling machine can achieve the sampling of underground mineral or set up underground item equipments. It could be faxed on some moving devices such as truck, trail car and pathway, or be faxed stationary on land and offshore structure, such as drilling platform, or be called as Offshore Oil Rig .
Numerous countries, such as America, France, Canada and Germany, all created numerous oil drilling rigs on and off to meet all kind needs of oil and gas reservoir at different areas. There is the improvement history of drilling rigs.
1. AC frequency conversion electric drive petroleum drilling machine. The core technologies of this machine is AC variable frequency speed control technologies. It is a comprehensive cross technology which involved motor theory, automatic manage theory, the circuit topology theory, energy electronics, micro-electronics and pc technology. It is an organic combination of modern high technologies and oil drilling machinery, and has strong vitality. It's the improvement trend of modern petroleum drilling rigs.
2. Laser drilling rig. Compared with standard drilling machines, laser drilling rigs don?¡¥t require drilling fluid, drilling bits, drill rods, oil tube and casing pipe, these characteristics would decrease the costing greatly. Meanwhile, laser drilling rigs have many other possible benefits, like light-weight, small floor space, quick speed, and could via numerous types of rocks. The most important benefit of laser drilling rig is that it is a clean break and may drill, melt and evaporate rocks. Due to this, there's no cutting back to the ground and have a smaller influence on the environment.
three. New Hydraulic Drilling Rig. This kind of rigs is formed by double acting hydraulic cylinder, moving yoke, lifting rope, balancer assembly, hydraulic cylinder guide frame, the leading drive device, hydraulic system and a few other parts. Its motion mode is converted easily. It has little volume and light weight. It would be used in some circumstances which have a higher requirement of drilling rig volume and quality if the reliability of hydraulic components can be enhanced in the future.
four. Continuous soft tube of oil drilling rig. Continuous soft tube is really a kind of steel tube with high intensity continuous manufacturing. Nowadays, the continuous length from the tube can attain to 7620 meters. The benefit of this drilling technology is primarily embodied in low cost, brief drilling time. It could attain synchronization in between measure and drilling and be utilized in re-drilling old wells, deepen the borehole and sidetracking.
Meanwhile, additionally, it can be used in underbalanced drilling operation to ensure operation safety. Continuous soft tube of oil drilling rig is very suit to drill little hole well and the improvement of offshore platform and the marginal oil field, for it has little floor space, small soft tube size and its equipments can be installed, tear downed and carried convenient. But the application of continuous soft tube technologies was restricted by some factors and only may be utilized in nicely drilling. On the other side, its service life is shorter than other equipments.
5. Casing drilling rig. This really is a new industry technologies of nicely drilling. Instead of drill rods, it use casing pipe to drill wells. It use leading drive device which is drove by electric and hydraulic. Generally, it is installed on trial car and to transmit the torque via the sleeve. Then this power will drive the drilling bit that is installed around the bottom of the torque to drill rotary. This structure is very simple to change the drilling bit and the operation is extremely handy and rapid.
Because the quickly development of economy, The study and manufacturing level of oil exploration equipment in our nation has made fantastic progress. There are much more and more professional drilling gear producers in China. Such as, there are a lot of producers produce diamond bits that is utilized in borehole drilling machine at present China. There are also a great deal of drill rods producers and water nicely drilling equipment surppliers, you are able to find each kind and model you want on-line.
