The variety of drilling machines and drilling equipments

Drilling machine is really a type of equipment that is used to drill within the earth surface. It includes some large-scale Engineering Drilling Rigs which are utilized to drill water well, oil well, and nature gas well. In the same time, it also consists of some small size equipments which can be moved by a single individual, and they are called twist drill or hand drilling machines. Drilling machine can achieve the sampling of underground mineral or install underground product equipments. It can be faxed on some moving devices like truck, trail vehicle and pathway, or be faxed stationary on land and offshore structure, like drilling platform, or be known as as Offshore Oil Rig .

Numerous countries, like America, France, Canada and Germany, all developed various oil drilling rigs on and off to meet all type needs of oil and gas reservoir at various locations. 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 control technology. It's a complete cross technology which involved motor theory, automatic manage theory, the circuit topology theory, energy electronics, micro-electronics and pc technologies. It is an organic combination of modern higher technologies and oil drilling machinery, and has strong vitality. It's the improvement trend of contemporary 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 characteristics would reduce the costing greatly. Meanwhile, laser drilling rigs have numerous other potential benefits, like light-weight, little floor space, fast speed, and could via numerous types of rocks. Probably the most important benefit of laser drilling rig is that it's a clean break and can drill, melt and evaporate rocks. Because of this, there's no cutting back to the ground and possess a smaller sized impact around 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 top drive device, hydraulic method and some other parts. Its motion mode is converted easily. It has little volume and light weight. It would be used in some circumstances which possess a higher requirement of drilling rig volume and high quality if the reliability of hydraulic elements may be improved within the future.

4. Continuous soft tube of oil drilling rig. Continuous soft tube is really a kind of steel tube with higher intensity continuous manufacturing. Nowadays, the continuous length from the tube can attain to 7620 meters. The advantage of this drilling technologies is mainly embodied in low cost, short drilling time. It could achieve synchronization between measure and drilling and be used in re-drilling old wells, deepen the borehole and sidetracking.

Meanwhile, additionally, it may be used in underbalanced drilling operation to ensure operation security. Continuous soft tube of oil drilling rig is very suit to drill little hole well and also the development 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. However the application of continuous soft tube technologies was restricted by some elements and only can be used in well drilling. On the other side, its service life is shorter than other equipments.

five. Casing drilling rig. This is a brand new industry technologies of nicely drilling. Instead of drill rods, it use casing pipe to drill wells. It use top drive device which 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 which is installed on the bottom from the torque to drill rotary. This structure is extremely simple to alter the drilling bit and also the operation is extremely handy and fast.

Because the quickly development of economy, The study and manufacturing degree of oil exploration gear in our country has produced fantastic progress. You will find more and much more expert drilling equipment producers in China. Like, there are a great deal of manufacturers create diamond bits which is utilized in borehole drilling machine at present China. You will find also a lot of Drill Rods Manufacturers Rock Drilling Equipment Manufacturers

 and water nicely drilling equipment surppliers, you can find every type and model you want on-line.
