The variety of drilling machines and drilling equipments

Drilling machine can be a kind of equipment that is utilised to drill inside the earth surface. It consists of some large-scale Engineering Drilling Rigs which are utilized to drill water nicely, oil well, and nature gas nicely. In the same time, in addition, it contains some little size equipments which may be moved by a single person, and they may be named twist drill or hand drilling machines. Drilling machine can achieve the sampling of underground mineral or set up underground product 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, for example drilling platform, or be named as Offshore Oil Rig.

A lot of nations, including America, France, Canada and Germany, all created different oil drilling rigs on and off to meet all type demands of oil and gas reservoir at diverse areas. There is certainly the development history of drilling rigs.

1. AC frequency conversion electric drive petroleum drilling machine. The core technology of this machine is AC variable frequency speed manage technology. It is a extensive cross technologies which involved motor theory, automatic control theory, the circuit topology theory, energy electronics, micro-electronics and personal computer technologies. It's an organic mixture of modern 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 decrease the costing drastically. Meanwhile, laser drilling rigs have many other possible positive aspects, like light-weight, modest floor space, fast speed, and could by means of numerous kinds of rocks. The most important advantage of laser drilling rig is that it is a clean break and may drill, melt and evaporate rocks. As a result of this, there's no cutting back to the ground and possess a smaller effect around the atmosphere.

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 best drive device, hydraulic program and a few other parts. Its motion mode is converted effortlessly. It has little volume and light weight. It could be used in some conditions which possess a high requirement of drilling rig volume and quality in the event the reliability of hydraulic components may be improved inside the future.

4. Continuous soft tube of oil drilling rig. Continuous soft tube can be a kind of steel tube with higher intensity continuous manufacturing. These days, the continuous length of the tube can reach to 7620 meters. The benefit of this drilling technology is primarily embodied in low cost, brief drilling time. It might achieve synchronization between measure and drilling and be used in re-drilling old wells, deepen the borehole and sidetracking.

Meanwhile, in addition, it may be employed in underbalanced drilling operation to ensure operation safety. Continuous soft tube of oil drilling rig is extremely suit to drill tiny hole effectively and the improvement of offshore platform along with the marginal oil field, for it has tiny floor space, small soft tube size and its equipments can be installed, tear downed and carried hassle-free. But the application of continuous soft tube technology was limited by some aspects and only can be employed in properly drilling. On the other side, its service life is shorter than other equipments.

5. Casing drilling rig. This can be a new sector technology of effectively drilling. Rather than drill rods, it use casing pipe to drill wells. It use top drive device that is drove by electric and hydraulic. Typically, it is installed on trial vehicle and to transmit the torque by way of the sleeve. Then this energy will drive the drilling bit that is installed on the bottom of the torque to drill rotary. This structure is extremely simple to modify the drilling bit as well as the operation is very practical and speedy.

As the swiftly improvement of economy, The analysis and manufacturing amount of oil exploration equipment in our nation has produced fantastic progress. You'll find more and more specialist drilling equipment manufacturers in China. Such as, you can find a whole lot of makers make diamond bits that is utilised in borehole drilling machine at present China. You'll find also a great deal of drill rods producers and water nicely drilling gear surppliers, you'll be able to discover every type and model you need on the internet.
