The variety of drilling machines and drilling equipments



Drilling machine is a type of gear which is used to drill in the earth surface. It consists of some large-scale Engineering Drilling Rigs which are utilized to drill water nicely, oil nicely, and nature gas nicely. In the exact same time, it also includes some little 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 install underground item equipments. It can be faxed on some moving devices such as truck, trail car and pathway, or be faxed stationary on land and offshore structure, like drilling platform, or be known as as Offshore Oil Rig .
Many countries, like America, France, Canada and Germany, all created numerous oil drilling rigs on and off to meet all type requirements 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 technology of this machine is AC variable frequency speed control technology. It is a complete cross technologies which involved motor theory, automatic control theory, the circuit topology theory, power electronics, micro-electronics and pc technologies. It is an organic mixture of contemporary higher technology and oil drilling machinery, and has strong vitality. It's the improvement trend of modern petroleum drilling rigs.
2. Laser drilling rig. Compared with conventional drilling machines, laser drilling rigs don?¡¥t need drilling fluid, drilling bits, drill rods, oil tube and casing pipe, these traits would reduce the costing significantly. Meanwhile, laser drilling rigs have many other possible benefits, like light-weight, small floor space, fast speed, and could via numerous kinds of rocks. The most important advantage of laser drilling rig is the fact that it's a clean break and may drill, melt and evaporate rocks. Because of this, there is no cutting back to the ground and possess a smaller influence on the environment.
3. New Hydraulic Drilling Rig. This sort of rigs is formed by double acting hydraulic cylinder, moving yoke, lifting rope, balancer assembly, hydraulic cylinder guide frame, the top drive device, hydraulic method and some other parts. Its motion mode is converted effortlessly. It has small volume and light weight. It could be utilized in some circumstances which possess a higher requirement of drilling rig volume and high quality when the reliability of hydraulic elements may be enhanced within the future.
4. Continuous soft tube of oil drilling rig. Continuous soft tube is a kind of steel tube with higher intensity continuous manufacturing. These days, the continuous length of the tube can attain to 7620 meters. The advantage of this drilling technologies is mainly embodied in low price, brief drilling time. It could attain synchronization between measure and drilling and be used in re-drilling old wells, deepen the borehole and sidetracking.
Meanwhile, it also may be used in underbalanced drilling operation to make sure operation safety. Continuous soft tube of oil drilling rig is extremely suit to drill little hole well and also the development of offshore platform and also the marginal oil field, for it has little floor space, small soft tube size and its equipments may be installed, tear downed and carried handy. But the application of continuous soft tube technology was limited by some elements and only may be utilized in well drilling. On the other side, its service life is shorter than other equipments.
5. Casing drilling rig. This really is a new business technologies of well drilling. Rather than drill rods, it use casing pipe to drill wells. It use top drive device that is drove by electric and hydraulic. Usually, it is installed on trial vehicle and to transmit the torque through the sleeve. Then this power will drive the drilling bit that is installed on the bottom of the torque to drill rotary. This structure is extremely simple to change the drilling bit and the operation is very handy and fast.
Because the rapidly development of economy, The research and manufacturing degree of oil exploration equipment in our nation has produced great progress. There are more and much more professional drilling gear producers in China. Like, there are a lot of producers create diamond bits that is utilized in borehole drilling machine at present China. You will find also a great deal of Drill Rods Manufacturers Rock Drilling Equipment Manufacturers
 and water nicely drilling gear surppliers, you can discover each kind and model you want online.
