The number of drilling machines and drilling equipments

Drilling machine can be a type of gear which is utilized to drill in the earth surface. It consists of some large-scale Engineering Drilling Rigs that are utilised to drill water well, oil nicely, and nature gas nicely. Within the same time, in addition, it includes some modest size equipments which may be moved by a single individual, and they may be called twist drill or hand drilling machines. Drilling machine can accomplish the sampling of underground mineral or set up underground solution equipments. It might be faxed on some moving devices such as truck, trail vehicle and pathway, or be faxed stationary on land and offshore structure, for example drilling platform, or be named as Offshore Oil Rig.

A lot of nations, including America, France, Canada and Germany, all developed different oil drilling rigs on and off to meet all kind needs of oil and gas reservoir at various places. There's the development history of drilling rigs.

1. AC frequency conversion electric drive petroleum drilling machine. The core technologies of this machine is AC variable frequency speed handle technology. It's a complete cross technologies which involved motor theory, automatic handle theory, the circuit topology theory, power electronics, micro-electronics and pc technology. It's an organic combination of contemporary higher technology and oil drilling machinery, and has robust vitality. It is the improvement trend of modern day petroleum drilling rigs.

2. Laser drilling rig. Compared with standard drilling machines, laser drilling rigs don?¡¥t want drilling fluid, drilling bits, drill rods, oil tube and casing pipe, these qualities would minimize the costing drastically. Meanwhile, laser drilling rigs have many other prospective advantages, such as light-weight, little floor space, quickly speed, and could via numerous types of rocks. Essentially the most crucial advantage of laser drilling rig is the fact that it's a clean break and can drill, melt and evaporate rocks. As a result of this, there is no cutting back to the ground and possess a smaller sized influence on the atmosphere.

three. 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 best drive device, hydraulic technique and a few other parts. Its motion mode is converted effortlessly. It has modest volume and light weight. It could be employed in some situations which possess a higher requirement of drilling rig volume and good quality when the reliability of hydraulic elements can be improved within the future.

four. Continuous soft tube of oil drilling rig. Continuous soft tube can be a form of steel tube with higher intensity continuous manufacturing. Nowadays, the continuous length on the tube can reach to 7620 meters. The advantage of this drilling technology is mostly embodied in low price, short drilling time. It can attain synchronization amongst measure and drilling and be utilized in re-drilling old wells, deepen the borehole and sidetracking.

Meanwhile, in addition, it might be utilised in underbalanced drilling operation to make sure operation safety. Continuous soft tube of oil drilling rig is extremely suit to drill modest hole nicely along with the improvement of offshore platform and also the marginal oil field, for it has little floor space, small soft tube size and its equipments can be installed, tear downed and carried practical. However the application of continuous soft tube technologies was limited by some aspects and only can be used in nicely drilling. On the other side, its service life is shorter than other equipments.

5. Casing drilling rig. That is a new industry technologies of well drilling. As opposed to drill rods, it use casing pipe to drill wells. It use top drive device which is drove by electric and hydraulic. Normally, it truly is installed on trial automobile and to transmit the torque through the sleeve. Then this power will drive the drilling bit that is installed on the bottom on the torque to drill rotary. This structure is very simple to alter the drilling bit and also the operation is extremely convenient and rapid.

Because the quickly improvement of economy, The study and manufacturing amount of oil exploration gear in our country has produced fantastic progress. There are more and much more skilled drilling gear manufacturers in China. Such as, you will find a good deal of makers make diamond bits which is used in borehole drilling machine at present China. You can find also a good deal of drill rods producers and water nicely drilling gear surppliers, you can find every sort and model you desire on the web.
