The number of drilling machines and drilling equipments

 Drilling machine is a kind of equipment which is used to drill in the earth surface. It includes some large-scale Engineering Drilling Rigs which are used to drill water nicely, oil well, and nature gas nicely. In the same time, additionally, it consists of some small size equipments which may be moved by a single person, and they're known as twist drill or hand drilling machines. Drilling machine can attain the sampling of underground mineral or install underground product equipments. It could be faxed on some moving devices like 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 nations, such as America, France, Canada and Germany, all developed numerous oil drilling rigs on and off to meet all kind requirements of oil and gas reservoir at various 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 technology. It is a comprehensive cross technologies which involved motor theory, automatic control theory, the circuit topology theory, energy electronics, micro-electronics and pc technologies. It is an organic combination of contemporary high technologies and oil drilling machinery, and has powerful vitality. It is the development trend of modern petroleum drilling rigs.

2. Laser drilling rig. Compared with conventional drilling machines, laser drilling rigs don?¡¥t require drilling fluid, drilling bits, drill rods, oil tube and casing pipe, these traits would decrease the costing greatly. Meanwhile, laser drilling rigs have many other possible advantages, such as light-weight, little floor space, fast speed, and could via various kinds of rocks. The most important advantage of laser drilling rig is the fact that it is a clean break and may drill, melt and evaporate rocks. Because of this, there's no cutting back towards the ground and have a smaller impact on the atmosphere.

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 components. Its motion mode is converted effortlessly. It has little volume and light weight. It would be used in some circumstances which have a high requirement of drilling rig volume and quality when the reliability of hydraulic components may be enhanced within the future.

four. 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 reach to 7620 meters. The advantage of this drilling technology is mainly embodied in low cost, short drilling time. It could achieve synchronization between measure and drilling and be utilized in re-drilling old wells, deepen the borehole and sidetracking.

Meanwhile, additionally, it may be utilized in underbalanced drilling operation to ensure operation safety. Continuous soft tube of oil drilling rig is extremely suit to drill little hole nicely and the development of offshore platform and the marginal oil field, for it has little floor space, little soft tube size and its equipments can be installed, tear downed and carried convenient. However the application of continuous soft tube technologies was limited by some elements and only can be utilized in nicely drilling. Around the other side, its service life is shorter than other equipments.

5. Casing drilling rig. This really is a brand new industry technology of well drilling. Instead of 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 via the sleeve. Then this power will drive the drilling bit which is installed on the bottom from the torque to drill rotary. This structure is extremely easy to alter the drilling bit and also the operation is very convenient and fast.

Because the rapidly development of economy, The research and manufacturing level of oil exploration gear in our country has made great progress. There are more and much more professional drilling gear manufacturers in China. Such as, there are a great deal of producers create diamond bits which is used in borehole drilling machine at present China. You will find also a great deal of drill rods producers and water well drilling gear surppliers, you can discover each type and model you want online.
