The variety of drilling machines and drilling equipments


Drilling machine is really a type of equipment which is used to drill within the earth surface. It includes some large-scale Engineering Drilling Rigs which are used to drill water well, oil well, and nature gas nicely. Within the same time, additionally, it consists of some little size equipments which may be moved by a single individual, and they are called twist drill or hand drilling machines. Drilling machine can attain the sampling of underground mineral or set up underground item equipments. It could 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 called 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 different locations. 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 manage technologies. 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 modern higher technology and oil drilling machinery, and has strong vitality. It's the development 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 decrease the costing significantly. Meanwhile, laser drilling rigs have numerous other potential benefits, like light-weight, small floor space, fast speed, and could via various kinds of rocks. Probably the most important advantage of laser drilling rig is 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 around the atmosphere.
3. 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 leading drive device, hydraulic method and a few other parts. Its motion mode is converted effortlessly. It has small volume and light weight. It would be used in some circumstances which possess a higher requirement of drilling rig volume and quality when the reliability of hydraulic components can be enhanced in the future.
four. Continuous soft tube of oil drilling rig. Continuous soft tube is a type of steel tube with high intensity continuous manufacturing. These days, the continuous length of the tube can attain to 7620 meters. The benefit of this drilling technology is primarily embodied in low cost, short drilling time. It could attain synchronization in between measure and drilling and be used in re-drilling old wells, deepen the borehole and sidetracking.
Meanwhile, it also can be utilized in underbalanced drilling operation to make sure operation safety. Continuous soft tube of oil drilling rig is very suit to drill small hole well and also the development of offshore platform and also the marginal oil field, for it has little floor space, little soft tube size and its equipments may be installed, tear downed and carried handy. But the application of continuous soft tube technology was restricted by some factors 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 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 car and to transmit the torque through the sleeve. Then this power will drive the drilling bit that is installed around the bottom of the torque to drill rotary. This structure is extremely easy to change the drilling bit and the operation is extremely handy and fast.
Because the rapidly improvement of economy, The study and manufacturing level of oil exploration equipment in our country has produced great progress. You will find more and much more professional drilling gear manufacturers in China. Such as, there are a lot of manufacturers create diamond bits which is utilized in borehole drilling machine at present China. There are also a lot of drill rods producers and water well drilling equipment surppliers, you are able to find each kind and model you want on-line.
